Quick Guide to Boss Materials in Diablo IV
Updated for Season 8: Belial's Return
Similar to my quick guide to mythic uniques (which aged like milk when they made things purple) I have memory problems when it comes to which bosses need which materials, and how many.
Sure, I could look at the items to see where they are supposed to be utilized, but this doesn’t give me any sense of how many I need to summon the (ideally, tormented) boss.
What usually ends up happening is that I’ll run off to the dungeon and check to see if I have enough materials to summon the boss. When I don’t, I’ll go check another dungeon. This cycle will continue until I get bored with not summoning bosses or an epic side quest presents itself!
This gets exacerbated when I say “nope, not enough mats” and the wife asks me how many are needed, and I’ve already run off without paying attention to the actual numbers. Yes, I look at to see if I can summon or not, it’s extremely boolean for how casually I play.
For this quick guide, I’m going to keep this simple. I will not delving into detail on where to farm each of the materials. Just focusing on how many of each material is required for each of the bosses in the rotation.
