I am trying to make a Drunken Brute Unchained Barbarian, and I came across the Combat Trait Accelerated Drinker. It allows you to drink a potion as a move action, presumably still provoking AOO since that ISN'T specified as being changed. I also came across a wonderful wondrous item, Drinking Horn of Bottomless Valor, which allows you to spend 1-3 charges with varying effects based on how many charges you spend. The parts I am focusing on are these:
So long as the horn has at least one charge remaining, it’s owner can command it to fill with mead or a similar alcoholic drink.
1 charge: The drinker gains 1d8 temporary hit points (as if from an aid spell), which last for 1 minute. Using 1 charge is similar to drinking a potion—it takes a standard action and provokes an attack of opportunity (though certain abilities can reduce the action required)
So, would the trait Accelerated Drinker apply to the 1 charge ability? Would it also apply to the mead or similar alcoholic drink?
If not, could anyone propose any way to speed up drinking in combat?
