Touch

If an effect has a range of touch, you must touch a creature or object to affect your target, which requires you to hit with a melee attack roll (against EAC unless the effect says otherwise) if you are touching an unwilling target. A touch effect that deals damage can score a critical hit just as a weapon can. Some touch effects allow you to touch multiple targets. You can touch up to six willing or unconscious targets as part of the activation of such an effect, but all targets of the effect must be touched in the same round that you finish activating the effect. If the effect allows you to touch targets over multiple rounds, touching up to six creatures is a full action.
