Hydrabox Runemaster Endgame Build
Last Updated: Jan 14, 2026 by Aaron ActionRPG
About
This an updated version to our Hydrabox Runemaster. The newest version is capable of clearing all pinnacle content and comfortably farms 800+ corruption.
This build has been automated to an extent, so as you cast your skills you will generate the runes necessary to trigger the Hydra sub-skill either by activating Runic Invocation or Flame Rush. Hydra can also trigger on kill with a fire skill thanks to our unique relic. Casting Frost Wall and then dashing through it with Flame Rush also gives us a boost in power for our next cast - which is usually Runic Invocation because it is partially automated through the use of Flame Rush. Flame Ward is used for survivability and Runebolt is our spam skills to generate runes for Hydra.
Please Note : Your skills have to be in the order on your skill bar as shown in the build guide to ensure Hydra box is being triggered properly.
