I’m a bit confused. Started fresh Sentinel, at lvl 15 took Dreamthorn, at lvl 19 started using Void Cleave with fire conversion (Riftflame/Hellish chasm nodes) Intention was later to move to fire damage and buff forged weapons/manifest armor.
After reaching mastery I decided to swap Dreamthorn to proper fire rare and suddenly realised that my damage halved. At first I thought the reason is added void dmg and penetration from unnique, but then… It should not be the point, cause all base damage was converted from void to fire.
Did a bit more testing. Equipped Dreamthorn again, it’s an only source of flat void damage and then removed both Hellish Chasm and Riftflame and DPS on tooltip dropped by only a fraction (and it was the loss of guaranteed ignite from Riftflame), as though none damage was fire at first place. I thought that going back from fire to void base damage will noticeably increase damage, but never happened.
Even with huge part of flat damage is void (40) the base weapon damage is 30 and it doesn’t have a specific element, so I assumed it should be same as base element of a skill.
Is this some kind of a bug or I missed something with mechanics?
