Mercenary Gear Options

General

• Cast Telekinesis on Waypoints to activate them, on Town Portals to get in or out of town, and on Red Portals to go through them. This allows you to travel through the game faster. Telekinesis can also be used to open chests and pop other clickables for loot.
• If you have Harmony equipped on Weapon-Swap, use it to travel faster through town.
• Before starting your Magic Find/Experience run, cast Frozen Armor and Thunder Storm once each. Refresh these buffs as soon as they expire (approx. every 2-3 minutes).
• Use Teleport to travel to your Farming Spot or between Elite Packs. Teleport is also crucial for repositioning.
• Engage enemies with either Lightning or Chain Lightning depending on the situation. Lightning is stronger against isolated, single targets and mobs in single-file lines. Chain Lightning is stronger against groups of spread-out mobs.
• Since both Lightning and Chain Lightning have high Damage ranges (with almost non-existent minimum damage), the number of casts required to kill your target mob(s) may vary drastically.

For Solo Gameplay:

• For maximum Solo-farming efficiency, target and kill Elite Monsters with Lightning and then immediately proceed to the next Elite(s). Don't waste time clearing minions or regular mobs while playing Solo or /Players1 on Single Player.

For High Player Count:

• Mostly use Chain Lightning to clear Elite Packs and high mob density. Use Lightning to finish off high value targets (such as Elites) after multiple Chain Lightning casts.
• Primarily use Lightning against mobs in single-file lines (such as in Arcane Sanctuary).
• When encountering high mob density with high Life (e.g. Baal Waves, High Player Count + any high density), first cast Static Field 1-3 times at close range, and then finish the mobs off with Chain Lightning and/or Lightning.

For Bosses:

• First cast Static Field 3-5 times in range of Act Bosses (such as Baal), Uber Bosses, or Diablo Clone in order to weaken them down to or near the 50% Life cap (in Hell).
• Next, "Telestomp" the Boss and repeatedly cast Charged Bolt in melee range. Stay directly atop the Boss to maximize Charged Bolt's damage. You can also use Lightning for a less consistent, safer approach.

Immunities

• Crack of the Heavens sets all Immune to Lightning monsters to 95% Lightning Resistance, allowing any sources of -x% to Enemy Lightning Resistance to take effect (including Conviction Aura from Infinity at 1/5th effectiveness).
• Break most Lightning Immunes using a Lower Resist Charge Wand on Weapon-Swap before obtaining Crack of the Heavens and/or Infinity or Plagues on your Mercenary.
• For unbreakable Lightning Immunes, "Telestomp" them with your Mercenary to kill them with his Physical Damage Jab attack. Alternatively, you can skip these monsters.
• Always skip Unique monsters that are both highly Lightning and Physical Resistant or Immune.

Late-Game

• Before starting your Magic Find/Experience run, first cast Battle Command 2 times and then Battle Orders once using Call to Arms. Refresh these buffs as soon as they expire (approx. every 2-3 minutes).
• Use Teleport to reposition your Mercenary close to enemies to apply Conviction Aura from his Infinity, reducing their Resistances and breaking Lightning Immunities. This also helps with procing Lower Resist using Plagues.

Optimal Loot/Experience Farming Strategies

• Baal - None of the monsters in Baal Waves are naturally Lightning Immune. A skillful combination of Static Field, Lightning, and Chain Lightning makes short work of Baal and his Waves no matter the Player Count. This build's fast Teleport is also incredible for efficient navigation to the Throne of Destruction.
• Uber Keys - Given her insanely high Teleport speed and the lack of troublesome Lightning Immunes surrounding Uber Key Bosses, the Lightning Sorceress is one of the most if not THE most efficient Uber Key farmer in the game.
• Arcane Sanctuary with 5-8 Players in the Game or /Players7 on Single Player - Having narrow paths and no Lightning Immune mobs, this is an ideal Farming Spot for the Lightning Sorceress. Even a Starter Lightning Sorceress can effectively farm this area (see Build Variants). Use Teleport to gather Specters and travel between Specter packs; use Lightning to accurately "zap" them over the solid platforms. Use Telekinesis to quickly open the Super Chests at the ends. The Specters and Super Chests in this area are highly efficient sources of Runes, Charms, Jewels, Gems, and Jewelry.

Faster Cast Rate (FCR)

Lightning/Chain Lightning

Teleport/Charged Bolt/Static Field

Faster Hit Recovery (FHR)

Gear Changes

• Damage Reduction: Equip Stormshield instead of Spirit. The % Damage Reduction and Increased Chance of Blocking granted by Stormshield both drastically improve your survivability. A setup using Stormshield socketed with a Ber Rune and either Enigma or Chains of Honor exceeds the 50% Damage Reduction cap. Crown of Ages and Verdungo's Hearty Cord are also great options for achieving high Damage Reduction on a Hardcore Lightning Sorceress.
• Faster Cast Rate: It can be difficult to achieve the 117% Faster Cast Rate (FCR) Breakpoint while prioritizing Damage Reduction on this build. Magefist and Trang-Oul's Claws are the Gloves that make it possible. Skin of the Vipermagi and Fortitude are the best Body Armor options for shoring up your FCR. Jewelry is also a great source of FCR.
• Stacking Resistances: Stack your Fire/Lightning/Cold Resistances beyond the default maximum values of 75 each (175 total in Hell). Stacking 85 additional Resistances in Hell completely negates the Conviction Aura of any Elite Boss or the Oblivion Knight's Lower Resist Curse. Beware of encountering both at the same time! Consider the primary damage type(s) of the monsters in the area you want to farm. Skin of the Vipermagi, Chains of Honor, and Fortitude are great Body Armor options for stacking Resistances on this build. Crown of Ages is a solid Helmet option. Boots, Jewelry, and Charms are also ideal sources of Resistances.
• Faster Hit Recovery: Aim for at least the 42% Faster Hit Recovery Breakpoint with your Charms, Boots, Helmet, and/or Shael Runes socketed into gear. Faster Hit Recovery is not as important when going for maximum Chance to Block (75%). You mainly rely on the Faster Block Rate Breakpoints attained by Stormshield socketed with a Ber Rune (27%) or Stormshield socketed with a Shael Rune (48%). 
• Lightning Absorb: Equip Thundergod's Vigor when farming or Teleporting through an area where Burning Souls are able to spawn such as Worldstone Keep/Throne of Destruction.

Stat Point Changes

• Allocate enough Stat Points into Strength to wear Stormshield.
• Allocate enough Stat Points into Dexterity to achieve maximum Chance to Block (75%) while having Stormshield equipped.
• Put all remaining Stat Points into Vitality.

Skill Point Changes

• There are no required Skill Point changes for a Hardcore Lightning Sorceress. However, allocating 1 Skill Point into Energy Shield and additional Skill Points into Telekinesis provides you with a decent Energy Shield, which redirects a percentage of the damage you take to your Mana Pool instead of your Life Pool. Energy Shield allows you to absorb high amounts of Physical Damage, such as from Undead Stygian Doll death explosions. It also provides some additional protection against Elemental Damage.
  
  See the "Hardcore" Build Variant below for additional suggestions and visuals.

• Teleport instantly moves you to a selected square on the visible screen in which you can stand. The game tries to to place you within a small radius around your cursor even if it would be impeded normally.
• Teleport is not obstructed by walls or other impediments but can fail if your cursor is not completely passed those impediments when cast. Your Mercenary travels with you.
• You can “extend” the visible screen by opening UI-windows like the Inventory or the Character screen. Continuously cast Teleport and drag your mouse to the edge of your screen.
• The Mana cost of Teleport decreases with additional Skill Levels down to 1 Mana per cast. This can easily be achieved on this build with just 1 Skill Point into Teleport and + to Skills on gear.
• You can use “ESC” to open the menu in single player to pause the game after a Teleport to determine if you are safe.
• Teleport cast speed is affected by the Faster Cast Rate Breakpoint that you achieve with your gear.

• Lightning pierces through monsters, dealing Lightning Damage to all monsters in its path. Line em' up and aim well!
• This Skill frequently one-shots your target(s) with its enormous maximum damage. However, extra casts of this Skill are often needed due to its almost non-existent minimum damage (if rolling low/bad RNG).
• This Skill benefits greatly from Conviction Aura, the Lower Resist Curse, and the -x% to Enemy Lightning Resistance stat on gear.
• Lightning, along with its sister Skill below, uses special Faster Cast Rate (FCR) Breakpoints. Unlike Teleport and most Sorceress Skills which require 105% FCR or 200% FCR, Lightning requires 117% FCR or 194% FCR.

• Chain Lightning arcs to nearby monsters after reaching its initial target. It arcs to a maximum number of monsters based on it's Level before expiring, dealing Lightning Damage to all monsters it passes through. Chain Lightning can seek out new targets or double back on previous ones depending on the number of nearby targets and where they are located.
• This Skill frequently one-shots your targets with its enormous maximum damage. However, extra casts of this Skill are often needed due to its almost non-existent minimum damage (if rolling low/bad RNG).
• This Skill benefits greatly from Conviction Aura, the Lower Resist Curse, and the -x% to Enemy Lightning Resistance stat on gear.
• Chain Lightning, along with its sister Skill above, uses special Faster Cast Rate (FCR) Breakpoints. Unlike Teleport and most Sorceress Skills which require 105% FCR or 200% FCR, Chain Lightning requires 117% FCR or 194% FCR.

• Static Field's range increases with its Level. It is the only thing that increases with its Level. 1 Skill Point and + to Skills from gear are sufficient for an effective Static Field in the late-game.
• In the Nightmare and Hell difficulty you can't reduce a monsters' Life past certain thresholds. For Nightmare this threshold is at 33%, in Hell it is at 50%. You can get a little past this threshold if your enemy has negative Lightning Resistance.
• In Normal difficulty you can bring a monster down to "1 Life". Static Field can't deal the final blow on a monster.
• Static Field works on any monster you encounter that is not Lightning Immune, including all Act Bosses, Uber Bosses, and Diablo Clone.
• Static Field reduces the current (remaining) Life of a monster by 25%. The Lightning Resistances of a monster will reduce its effectiveness.
• Damage calculation: Monster Life = Current Life - ((Current Life * 0.75) * ((100-Lightning Resistance) / 100))
• Unlike Lightning and Chain Lightning, this Skill uses the standard Sorceress Faster Cast Rate Breakpoints (105% and 200%).

• Charged Bolt emits Lightning Bolts in a cone in front of your Sorceress. Each Bolt applies Lightning Damage to an enemy it makes contact with. This Skill can emit a maximum of 24 Bolts per cast based on its Level.
• These Bolts do not pierce; they do not pass through enemies. They deal their damage and disappear upon making contact with an enemy.
• If you Teleport directly on top of a single target ("Telestomp"), you can "shotgun" the target with Charged Bolt, hitting it with every Bolt at once. This is useful for applying consistent damage to Act Bosses, Elite Monsters, Uber Bosses, and Diablo Clone.
• This Skill benefits greatly from Conviction Aura, the Lower Resist Curse, and the -x% to Enemy Lightning Resistance stat on gear.
• Unlike Lightning and Chain Lightning, this Skill uses the standard Sorceress Faster Cast Rate Breakpoints (105% and 200%).

• Thunder Storm is an offensive buff that strikes a random nearby enemy with a bolt of Lightning every couple of seconds. This buff's damage and duration increases with its Level. An Aura effect under your Sorceress indicates that this buff is active.
• Every Bolt deals a consistent amount of Lightning Damage, often putting enemies in Hit Recovery. This mini-stun can be annoying, however, while trying to line up Specters for Lightning in Arcane Sanctuary. Thus, it is not recommended to use this Skill there.
• 1 Skill Point and + to Skills from gear is enough for Thunder Storm to deal decent intermittent single target damage.

• Telekinesis is a Utility Skill that is primarily used for activating Waypoints, going through Town Portals, popping clickables, and picking up certain items from afar. It also knocks back enemies.
• Telekinesis can be used to pick up Scrolls, Potions, Gold, and other consumable items from a distance. It cannot pick up standard equipment like Weapons, Body Armors, and Shields; it also cannot pick up Socketables like Runes, Jewels, or Gems.
• In addition to being able to use Waypoints and Town Portals from afar, this Skill can also be used to enter Red Portals such as the Mephisto Red Portal to Pandemonium Fortress.
• Using Telekinesis is the most efficient way to pop clickables (like chests) for loot. It is also the best way to pop seals in Chaos Sanctuary.
• You can repeatedly cast Telekinesis to "perma-stun" a monster against a wall; this can allow your Mercenary to more easily kill a strong Lightning Immune monster.
• Telekinesis CAN be used to deal Lightning Damage to enemies. However, it deals very little damage even if maxed and can only be applied to a single target.
• Telekinesis uses the standard Sorceress Faster Cast Rate Breakpoints (105% and 200%).

• Frozen Armor applies a Defense buff that scales based on its Level and the Defense stat on your gear. It also temporarily Freezes enemies that strike your Sorceress.
• Frozen Armor only works against melee attacks. It does not work against ranged attacks.
• 1 Skill Point and + to Skills from gear is enough for Frozen Armor to do its job. However, you can choose to put additional Skill Points into Frozen Armor instead of Warmth past Level 94 for an increased Defense bonus.

• Energy Shield is a defensive buff that redirects a percentage of the Damage you take to your Mana Pool instead of your Life Pool. This percentage is based on the Skill's Level. This buff has an especially long duration, which increases with the Skill's Level. A golden sphere above your Sorceress' head indicates that this buff is active.
• Allocating Skill Points into Telekinesis, Energy Shield's Synergy, increases Energy Shield's effectiveness by reducing the amount of Damage taken to your Mana Pool per point of Damage (i.e. With 0 Hard Points into Telekinesis you lose 2 Mana per 1 Point of Damage. With 20 Hard Points into Telekinesis you lose .75 Mana per 1 Point of Damage).
• This Skill can be very hard on your Mana Pool. Keep at least 2 full rows of Mana Potions in your Belt while this Skill is active.
• Energy Shield deactivates if you take damage at 0 Mana. For this reason, Energy Shield is more effective the higher your Mana Pool is. Refresh this buff ASAP to prevent your Life Pool from taking 100% of the damage like normal.
• Energy Shield is most effective against guarding your Life from Physical Damage, but drains your Mana quickly versus Elemental Damage. Additionally, Energy Shield loses significant effectiveness when up against the Unique monster Mana Burn stat or the regular monster Drains Mana stat. In these situations, Energy Shield can even cause your Mana to drain so fast to the point that you cannot cast Teleport and can prove Deadly. Because the Mana Burn/Drains Mana monster stats exist, allocating all (or nearly all) your Stat Points into Energy and solely relying on high Level, high Mana percentage Energy Shield is especially risky.
• Energy Shield does not work against Poison Damage. Poison Damage is always taken by your Life Pool.
• Resistances do not apply to damage taken on Energy Shield.
