Welcome to the Hydrahedron Runemaster Guide. Fill the battlefield with fiery octahedrons that spew a deadly rain of Fire Projectiles that incinerate everything in the area! Combine Lightning, Fire, Fire (L,F,F) Runes to conjure Hydrahedron, a powerful Runic Invocation unique to the Runemaster that turns foes into ashes.
Generate Lightning Runes with Runebolt and Fire Runes with Flame Rush, a powerful dash that casts Runic Invocation on use and grants great defensive buffs. Flame Ward is an incredible Defensive Skill with tons of Damage Reduction that can save the Runemaster even from the most dangerous attacks. Frost Wall provides additional DPS and grants Flame Ward on ally pass through.
This setup doesn't require any Unique to function. However Items like Box of Hydrae and Fundamental Criterion have the potential to enhance the build's power tremendously, especially with Legendary Potential.
Overall the Hydrahedron Runemaster is a great build suited for all the content in the game, even in Hardcore. If you are looking for the classic Fire turret playstyle, this build is perfect for you!

Gear
Gearing in Last Epoch revolves around finding Items and then using the powerful Crafting System to enhance them. As long as an Item has Forging Potential left, players can upgrade or modify their Affixes up to Tier 5. However, the powerful Exalted Tier Affixes are drop only and can't be modified by players.
Using the correct Item Bases allows you to make use of their amazing Implicits, this is fundamental for gearing efficiently. Combine Implicits, Passives, Idols and Blessings to cap your Resistances and other defensive layers, while fitting as much Health related Affixes, Ward or Endurance Threshold into your gear as possible. Plan ahead for your next upgrades and consider the final Empowered Blessings of your build while gearing. Finish up by farming Uniques with Legendary Potential and Sealing Affixes into Exalted Items to unleash all of your build's power!
Here are the Stat Goals for this build:
- Capped Resistances
- Capped Critical Strike Avoidance
- 3000 - 10000+ Ward (while in combat)
- 400+ Ward Retention
- 45% - 65%+ Armour
- 40 - 65+ Attunement
- 50 - 80+ Intelligence
- 300+ Mana
- 300%+ Spell Critical Strike Multiplier
- 40% - 90%+ Movement Speed
Gear Progression
Milestone 1
Aim for good Item Bases with two valuable T5 Affixes. The Defensive rolls on T5 Suffixes are very important at this stage as they can easily cap all your Resistances when combined with Item Implicits, Idols, Blessings or Passives. Get a Weapon with double T5 offensive Prefixes as soon as possible.
Milestone 2
Make sure your Reduced Damage Taken from Critical Strikes is capped. Remember that Woven Flesh is always an option early on. It can be farmed by killing the Abomination in the Fall of the Outcast Monolith Timeline.
Milestone 3
Get as much Increased Cooldown Recovery Speed as possible to be able to spam Flame Rush more often.
Milestone 4
Aim for T5 Level of Runic Invocation on your Helmet to further invest into its Tree. T5 Penetration with Fire Invocations is also a great upgrade.
Milestone 5
While you look for this basic set of gear, start farming your Empowered Blessings and look for any Idols that can help you cap all your Resistances momentarily or increase your Damage output. Make sure you have at least 300 Mana if you find Idols with Increased Fire Damage (Doubled If You Have Over 300 Max Mana) to increase your DPS.

Cruelty of the Meruna - Survival of Might

Other useful Idol Affixes

Build Scaling

- Critical Strike Multiplier: Increases the Damage your Crits deal. Build as much as you can on your gear.
- Frost Wall: Has built in Fire Resistance Shred thanks to this Node. Since the build attacks so fast and has many hits, it is extremely easy to apply the maximum 10 stacks to your targets, increasing the Fire Damage enemies take by 50% (20% for Bosses).
- Chance To Shred Armour on Hit: Each stack of this Ailment reduces enemy Armour by 100 for 4 seconds and stacks infinitely. Enemies have 0 Armour by default and it can go into the negatives.

Recommended End Game Activities
Last Epoch has multiple end game activities with completely different roles and rewards. All the builds in Maxroll.gg have been tested and are designed to complete all available content. However, not all builds excel at doing the same activities. Make sure you are familiar with the end game strengths and weaknesses of your character.
The Monolith of Fate is the main end game system. Most of your character gear upgrades are found here. Once you get all of your desired Empowered Blessings, you can start pushing Corruption to increase your chances at finding incredible Exalted Items. The Monolith of Fate rewards speedy builds that are able to target farm Echo Reward Nodes or stack Timeline Stability as fast as possible.
This Runemaster is a great Monolith of Fate farmer. It's very safe and has great range. While it's not the fastest build for rushing objectives, it's a balanced setup that can do it all.
Monolith Goals

Your goals in the Monolith of Fate will differ greatly depending on what build you play and what stage your character progression is at. Here are the objectives you should aim at when playing this build:
- Reach Empowered Monolith as fast as possible.
- Farm your Combat Empowered Blessings. Prioritize gaining Timeline Stability and fight the Timeline Bosses as often as possible. Once you are done with one Timeline, move to the next one. Reach 200 Corruption to farm your desired Blessings faster, as it unlocks a 5th option to choose from after you defeat a Timeline Boss. Defeat the Shade of Orobyss to gain and transfer Corruption between Timelines.
- Farm your first Drop Rate Empowered Blessing in The Stolen Lance Empowered Monolith Timeline. Here you should also farm Throne of Ambition until you get it.
- Finish up the rest of your Drop Rate Empowered Blessings.
- Farm for key Uniques.
- As you farm for Uniques, stack Corruption as high as your gear can handle. The higher Corruption you do, the more Items you find. Get your character ready for the other end game activities.
Monolith Modifiers
Every time you choose an Echo a Modifier comes attached with it, adding difficulty and changing how enemies behave. These Modifiers stay active for a maximum of 6 Echoes and stack with each other. Some Modifiers can handicap your build immensely while others can almost be ignored. Monolith Modifiers scale with Corruption and increase the Item Rarity of Echoes. Ideally you want to do the hardest content possible, without delaying your clear times. Keep up Item Rarity as high as you can without it slowing you down.
Easy Modifiers
- Enemy Critical Strike Chance (Once you have 100% Critical Strike Avoidance).
- Enemies heal if they have not been damaged recently.
- Rare enemies have high speed and crit chance until approached.
- Rare enemies regenerate health.
