Hydrahedron Runemaster Guide
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.
Use any Skill to generate Lightning and Fire Runes based on the order of your Skills on the Action Bar, then use 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 a multitude of Buffs.
This setup doesn't require any Unique to function. However, it is centered around the powerful Reowyn's Fortress, which rewards you from scaling Ward, Armor and Dodge equally. Fundamental Criterion, Telf'un's Mirage, and Box of Hydrae bolsters the builds power, while Red Ring of Atlaria and Omnis are great to increase survivavility.
Overall the Hydrahedron Runemaster is a great build that performs well in the endgame. If you are looking for the classic Fire turret playstyle, this build is perfect for you!
This build benefits from Attribute swapping Oerden's Watch Woven Echo. It is the only way to get Attunement on a Mage specific non-Unique item.
This build guide assumes you have a Level 70 Character.

Skills
Runic Invocation
Combine Lightning, Fire, Fire (L,F,F) Runes before casting Runic Invocation to conjure Hydrahedron, your main Damage Skill. In this setup, it is automatically cast from Flame Rush thanks to Epilogue. Immutable Order locks in the order of runes you gain, following the order of your skills on the Action Bar from left to right. To generate the correct sequence, place Flame Ward, Flame Rush, then Frost Wall in that order.
- Runic Invocation: Enigma is used to get double value from Nimbus Walk. You will gain Ward from Runic Invocation and Flame Rush since both skills have the Traversal Tag.
Frost Wall: The Damage buffs from Aspirant's Arrival when passing through Frost Wall doesn't expire as it should on your next cast of Runic Invocation. As long as you don’t manually use Runic Invocation or pass through another Frost Wall, the Damage Multiplier persists.
Using this bug is not needed for this build to excel, and is subject to being fixed during the current Season. The Tier Lists do not take into account this bug.
