 Teleportation and Sneak Attacks
A character who teleports behind or out of sight of an opponent can make a Hide check opposed by the target’s Spot check. If successful, the character gains a +2 bonus on attack rolls against that target and negates any Dexterity bonus to the opponent’s AC. This also allows the character to make a sneak attack against the target, if using a melee weapon or a missile weapon within 30 feet of the target.
