Zombie Wizards will replace Wither Skeletons, they are some kind of an evil antipode to Wizards. They are aggressive towards player and Wizards, and will constantly throw fireballs untill you're dead.
Acolyte is a former Skeleton, he won't shoot arrows at you, instead he will set you on fire in melee combat. When Wizard dies, his soul goes to the heaven and his body becomes an Acolyte.
You'll be able to become a magician too, just put on Wizard's Robe (Chainmail Armor) and take a Magic Wand (Bow and still need arrows) to throw lightning bolts on your enemies heads.
