Most of the special, random modifiers found on bosses in Diablo 3 are reminiscent of {{iw|Monster_modifier#Unique_Monster_Bonuses those seen in Diablo 2}}, but there are some new ones mixed in. All of the bosses seen (on normal difficulty) in the Blizzcon 2008 and 2009 demos had at least one modifier, but quite a few had two. It's not known if the bosses with two mods were [[SuperUniques]] sporting their own innate mod + a random one, or if some bosses can just spawn with multiple modifiers on normal difficulty.
