In the wintertide theres a boss called Dalvo's Astral Projection who is immune to Crushing, Slashing, Piercing, Fire, Cold, Poison, Nature, Acid, and Trauma. Which is all my attacks as an Archer/BC. If I have a mod say that puts a fire dot when I use a bomb attack is he also immune to that since he is immune to fire or are mods treated differently? Should I need to skill up 2 alternate skills just for that one boss? Currently working mentalism/priest, but its going pretty slow so Im asking to see if its really necessary or if theres another way.
