Benefit(s): As long as you have at least 1 point in your ki pool and have a hand free, you are considered armed for the purpose of threatening attacks of opportunity. If a creature provokes an attack of opportunity from you, you can spend 1 point from your ki pool to enhance your attack of opportunity as though you had the Arcane Strike feat (treating your character level as your caster level, even if you are not able to cast arcane spells.
Alternatively, when a creature provokes an attack of opportunity from you, as an immediate action you can target that creature with a harmful 1st-level spell-like ability that you possess, including any harmful bloodline ability, domain power, witch hex, or wizard school power that you gained at 1st level by spending 1 point from your ki pool. This ability affects only the targeted creature, even if it normally affects more than one creature or affects an area. Using this ability does not provoke an attack of opportunity from your target, though it may provoke attacks of opportunity from other creatures that threaten you.
Normal: Attacks of opportunity must be performed with weapons.
