The necromancer is a powerful hostile mob in Minecraft that can summon undead mobs with his staff, as well as create blue laser balls that cause damage to the player. The necromancer appears as a large skeleton in clothing and a headdress that resembles a golden crown. If the player gets too close, a necromancer runs away to a safe distance and then summons mobs again. The Minecraft cursor and game pointer with Necromancer and Staff!
