These actions take essentially no time at all, though the GM may restrict how many free actions can be taken to whatever could realistically be accomplished in about 6 seconds.
Delay: You choose not to act on your turn in initiative, forfeiting your original initiative position and waiting until a later time to act. Unlike readying an action, when you delay you cannot respond directly to an opponent’s action, nor interrupt their actions. You must wait until a creature has completed their turn before moving yourself back into the initiative order at your new initiative position. However, also unlike readying an action, once you cease delaying, you can take your full turn rather than only a single readied action.
If you do not establish a new initiative position before the turn order returns to your previous initiative position, you forfeit the previous round’s actions and begin your next turn, though you may delay again. If you are affected by an ongoing effect, that effect occurs at the beginning of your turn, before you have acted. If you then Delay taking your actions until a later initiative count, that ongoing effect does not recur when you take your actions. Once you have acted and reset your initiative count (or if you forfeit your actions and your initiative count does not change), any effects still ongoing recur the next time your initiative count comes up.
You cannot Delay if you are not already in combat.
Drop a Held Item: You drop anything you are wielding or holding in your hand.
Drop Prone: You move from a standing or kneeling position to prone on the ground.
Drop to Your Knees: You move from a standing to a kneeling position.
Let Go: You release your hold on a creature or object, including someone you were grappling. When wielding an item with two hands, you can use this action to let go with one of your hands.
Speak: You can speak short phrases or answer simple questions. You cannot engage in complex discussions or debates as a free action.
Stop an Action: If you are in the midst of performing an action, you can stop that action at any point. You are never obliged to complete an action that has several parts, such as movement or a full attack action.
