Megabosses

Mega-Bosses
Mega-Bosses are high-teir bosses that occur at the midway point between every 10 bosses. They are unique from other bosses in that they have significantly larger health pools, deal more damage, and come with the unique buff Mega-Boss Immunities or Mega-Boss Resistance. Sometimes both. Mega-Bosses typically also have a buff unique to only them.
