I like those suggestions but would also settle for longer durations on garrote, rupture and SnD. You’re constantly having to refresh one of the three and leaves little opportunity to really get a bunch of envenoms in.
Id say Exsanguinate refreshes duration on garrote and rupture to max with the normal effect it has now. Creeping venom stacks an absorb heal effect. Bring master assassin talent up to 100% to make legendary diversity.
Toxic Blade is literally already baseline. With how many people there are that don’t seem to realize this, I wonder if that’s the reason Sin looks so bad in logs? lmao
