Boss weaknesses, one table.

Damage types run on a combat triangle, so bringing the wrong weapon to a boss is the slowest way to learn its resistances. This is every charted boss with what it is weak to, what it shrugs off and what simply does not stick. Each name opens the full bestiary entry with drops, attacks and locations.

Reading the table

Weak to means bonus damage: lead with that type. Resists means reduced damage, and immune means the effect does not apply at all, so an immune-to-poison boss makes poison weapons dead weight. Elemental weaknesses (Air, Fire, Water, Earth) apply to spells, where the element comes from the rune you cast rather than the weapon. To check a specific loadout against a specific boss, pick pieces in the gear comparison and set the boss as the target.
