Wardens law does not appear to properly work using the new seasonal mods for handcannons or atleast the barrier mod. Ive tested it against all the known enemies it works against. It will break through hob goblins invulnerability when healing but not with hydras shields, cabals shield or the actual barrier champions( will do no damage whatsoever until unshielded). For the unstoppable mod i haven't used with other weapons but for wardens it does work but deals only half its damage whether intended or not im not sure.
