Pathfinder material appears to have some conflicts over how long it takes to drink a potion.
From the PRD page on Potions:
Drinking a potion or using an oil is a standard action. (...) Using a potion or oil provokes attacks of opportunity.
Potion Glutton feat says, however:
Benefit(s): You can drink potions, elixirs, or other potables as a swift action without provoking attacks of opportunity.
Normal: Drinking potions is a move action that provokes attacks of opportunity.
While the Accelerated Drinker trait says:
Benefit: You may drink a potion as a move action instead of a standard action as long as you start your turn with the potion in your hand.
What is correct? Standard or move action?
