Teleporter

Teleporting is a returning boss modifier from Diablo II.

This modifier allows the boss to teleport after a certain interval, which appears to coincide with the cooldown on the Wizard's teleport spell (which is roughly six seconds). Unlike Diablo II, however, bosses with teleport do not appear to replenish health upon teleportation. When added with a modifier such as vampirific, it would be incredibly unfair to the player, but perhaps poetic justice served after years of being pummeled by characters loaded to the gills with life leech.
