When a creature makes an attack against the phantom's master, the phantom gains a +2 bonus on attack rolls against that target, and deals damage against that target as if the phantom were one size category larger. For the purposes of this ability, an attack includes any harmful spell targeting the spiritualist master of whose area or effect includes the spiritualist master. Dutiful strike lasts for 1 minute, until another creature attacks the phantom's spiritualist master (at which point this effect transfers to the new attacker), or until the attacking creature is reduced to fewer than 0 hit points, whichever occurs first.
