Welcome to the Ice-Fire Fusion Gemma Leveling Guide. Gemma's Ice-Fire Fusion Trait specializes in combining damage types from multiple elements, Frostfire Strength applies Fire damage bonuses to Cold damage and vice versa. This makes her an excellent choice for mixing and matching Elemental Skills of almost any type because you apply all your damage bonuses to any of them.

The leveling guide is intended to take your character to Level 90.
This is the last level with unlimited free respec points.
Be sure to check the final section of the guide for recommendations on how to transition into the Endgame!

Check out the Complete Story Walkthrough for tips on how to complete the Campaign.

Treasure Troves

Treasure Troves are a way to super-charge your leveling experience. They give vastly more experience than regular zones and yield exclusive Legendary items. You need to complete each of them once for a Talent Point. For an easier leveling experience, you repeat the Treasure Trove until you're 8-10 levels above the zone, then rush through the next few areas. Follow your side quest to find the Treasure Trove locations.

Keep an eye out for the following Legendary items as you clear Treasure Troves.

  • New Ear Hills (L7): Look out for Pentagram Astrolabe, Lonesome and Glorious Journey.
  • Nectar Valley (L16): Look out for Omniscient Prototype.
  • Dawn Avenue (L27): Look out for Omniscient Prototype.
  • Sanctuary of Solitude (L35): Look out for Lonesome and Pentagram Astrolabe.
  • Silver Sands' End (L44): Look out for Howling Wind, Surging Inspiration - Prototype and Marksman Bracers.
  • Hall of Grandiosity (L54): Here you should farm to level 60 to reach your next Hero Trait before completing the campaign.

Leveling Tips and Tricks

  • Your first active skill slot (top left in the Skills menu) is your "Main Skill," this matters because many items and Hero Traits have effects that only apply to the Main Skill.
  • If you're ever in doubt of where to go, click the campaign quest on the left of your screen and a golden path shows you the way.
  • This guide assumes you get most of your levels through Treasure Troves and rush to the objectives in other zones for maximum efficiency.
  • When allocating Pact Points, prioritize Elemental Resistance first, then select Damage nodes until you fill the section. If you have leftover points, put them into Drop nodes as you begin farming the Netherrealm.
  • Complete all 10 Levels of the Hero Forge to unlock all of your Hero Trait abilities and gain 6 additional Talent Points.
  • All support gems become available from the Skill Shop at level 55. At this stage cross reference with the embeds to make sure you're set up for the Netherrealm.
  • In Chapter 3 gear you find comes with varying amounts of Energy, after changing your gear, be sure to go to the Energy Menu under Skills to reassign missing Energy.

Equipment & Stat Priorities

Main stats to be looking for while progressing the campaign

Look for these Offensive stats on weapons:

  • Intelligence
  • Fire damage added to Spells
  • Cast Speed
  • % Elemental Damage
  • % Spell Damage
  • % Projectile Damage
  • % Projectile Speed

Look for these Defensive stats on armor:

Core Skill

  • Build stacks of Fusion Energy by using skills tagged with Fire or Cold to use Frostfire Rampage; Gemma's signature ability that causes you to deal significantly more Elemental damage.
  • Split Firebolt is a projectile skill that splits and explodes upon hitting an enemy, it also gains massive power from Spell Burst. Use it when you are waiting for your Terra Charges to recharge.
  • Flame Jet is a Terra skill meaning it has 0 cast time. Use it when you have 3 Terra Charges to efficiently kill packs of enemies whilst on the move.
  • Mana Boil is an empower skill that provides a passive bonus granting additional Spell Damage by draining 5% of your mana per second. With enough levels in Magical Source you should have almost permanent up time on this buff.
  • Spiral Strike is the fastest mobility choice.

The Netherrealm

Racing through your Netherrealm quests as quickly as possible results in you becoming under leveled for the required zones to progress further, stay within 3 levels of the zones you're completing to avoid a harsh experience penalty. Check out our How to Progress the Netherrealm if you're unsure of anything.

Here's a list of things to do while progressing the early stages of the Netherrealm;

  • Level 60, The Trade House is unlocked. Be sure to read and understand our Trade House for Beginners Guide before making any big purchases.
  • Higher item levels of gear come with higher quantities of Energy. Look to improve your current gear with items that have increased energy so that you can use more Support Skills.
  • Utilize Prototype Crafting and Enchanting to greatly increase the power of gear you come across. It costs very low amounts of Flame Sand to lock 1 good affix in place and reroll up to 4 new modifiers. Legendary Gear with Legendary Aptitude allows you to roll mods and craft on those items well.

Transitioning to Endgame


Focus on acquiring either 2 Wands or a Staff with the "Additional damage for Skills cast by Spell Burst " mod;

  • Search Beacons or the Trade House for items with any of the following modifiers on Staffs or Wands.
    • Intelligence
    • Additional Levels to Fire or Spell Skills
    • Additional damage for Skills cast by Spell Burst.
    • Fire Damage
    • Critical Strike Damage
    • Gear Critical Strike Rating
    • Elemental Penetration
    • Cast Speed
  • Craft the items using prototype crafting until you have Spell Burst modifier as well as multiple modifiers listed above.
  • Enchant the item with a 5th modifier.

Legendary Items


  • Spring Resurrection is a great early game weapon for any caster build.
  • Chain of Resistance grants additional damage against Single Targets and Area of Effect whilst clearing groups of monsters.
  • Grace Boots provide Focus Blessing generation as well as additional movement speed, Life and Energy Shield.
  • Elemental Whisper Belt adds flat Elemental damage to spells, but quickly gets outclassed by a well crafted belt.
  • Pentagram Astrolabe provides 5 random elemental modifiers.

Set Items

As you complete the Netherrealm you encounter Chaos Cards that provide a Set Item. These items are very powerful at a base, and provide powerful set bonuses. Be sure to farm the following Voyager's Commemorative Set Items;

  • Voyager's Commemorative Boots
  • Voyager's Commemorative Brooch
  • Voyager's Commemorative Cape
  • Voyager's Commemorative Cufflinks
  • Voyager's Commemorative Goggles
