Fire Enchanted

• Adds fire damage equal to its monster level × 66% to 100%: a level 80 unique adds 52-80.
• +75% fire resistance, under the same immunity rules as Magic Resistant.
• Its minions add fire damage too in Nightmare and Hell (monster level × 33% to 50%), not in Normal.

The death explosion

• Only the unique explodes. Its minions never do, a super unique's included.
• Half physical, half fire damage, worth a share of the life of a normal monster of the unique's level: 11.25-18.75% in Normal, 7.5-12.5% in Nightmare, 1.95-3.25% in Hell.
• Its radius grows from about 2.7 yards in Normal to 4 yards in Hell.
• It only hurts players, not mercenaries or pets. It can be blocked or avoided, and a critical hit doubles it.
• Patch 2.4 lowered the explosion in Nightmare, where it used to be stronger than in Hell.

• Step back before the killing blow, or kill it from range: the explosion only reaches nearby players.
• Fire resistance lowers the fire half of the explosion.

Every modifier a unique monster rolls is drawn from the same pool, so each roll has the chance below of being Fire Enchanted. See how special monsters get their modifiers.

• Its minions add fire damage in Nightmare and Hell, but don't get the fire resistance and don't explode.
