I play a fighter who has the feat Quick Draw. After making the Str check to set a bear trap, there's no limit to the length of time the bear trap remains set. Dropping an item is a free action. Could my fighter dump, like, a dozen already-set bear traps from his inventory in one round using only a free action for each bear trap?
Much to sorrow of those aspiring to cartoon coyotehood, the feat Quick Draw is disappointingly specific:
You can draw a weapon as a free action instead of as a move action. You can draw a hidden weapon (see the Sleight of Hand skill) as a move action.
A character who has selected this feat may throw weapons at his full normal rate of attacks (much like a character with a bow).
Alchemical items, potions, scrolls, and wands cannot be drawn quickly using this feat.
Assuming a house rule hasn't added to Weapons the bear trap, it typically takes a move action that provokes an attack of opportunity to retrieve a stored item such as a bear trap, which usually limits a creature to dropping, during its turn, any number bear traps held in hand plus two.
To overcome this unfortunate limitation on the feat Quick Draw, take the third-party feat Organized Inventory.
Possibly, but you should ask your DM.
Free actions don't take any time at all, though there may be limits to the number of free actions you can perform in a turn. Free actions rarely incur attacks of opportunity. Some common free actions are described below.
