Haven build calculator

Pick a melee weapon and enter your bonuses. Bonuses of the same kind add together, and the kinds multiply, which is what both in-game tests and the game data show. Weapon numbers are The Dungeon Fish's measurements at weapon level 101 against one target. Treat the results as a way to compare builds, not exact damage.

Each element bonus only boosts the share of a hit that is that element. Set the shares for your weapon. The Gauntlets default to half lightning and half frost, following DungeonsDB. Lightning Surge waves count as all lightning here.
