A GM/player is thinking that the Alchemist Discovery Explosive Missile also allows the character to avoid AoO's when firing in melee. This does not sound right to me, but wanted to run by folks here.
His logic chain is that Discoveries are a Supernatural ability. Supernatural abilities do not provoke AoO's. Explosive Missile says as a standard action the alchemist can infuse a single arrow, bolt, or one-handed firearm bullet with the power of his bomb, load the ammunition, and shoot the ranged weapon.
His belief is that the entire action is done under a Standard action, but since it is the supernatural ability of explosive missile that allows you to do multiple actions under one standard action then the action is treated as only using your supernatural ability, therefore no AoO when firing the ranged weapon in melee.
I am more inclined to think the multiple actions still retain their normal action type and it is simply the supernatural ability that lets you do more than one of them in a single standard action, so the firing of ranged weapon in melee still provokes an AoO.
Anyone want to weigh in?
