You don’t need to ready an action in order to make an opportunity attack. You can make an opportunity attack when a hostile creature that you can see moves out of your reach. To make the opportunity attack, you use your reaction to make one melee attack against the provoking creature.
Can you change a held action 5e?
Yes, you can. It is an action just like any other, and is taken on your turn. Secondly when the trigger goes off do you have to wait for your turn or do you in effect get a bonus turn?
Can you prepare move and attack as a readied action?
You can’t prepare move and attack as a readied action, you have to pick one. Also, you only get one attack even if you would normally get more than that. RAW implies that it can only be an action, so you can’t ready movement. You could, however, ready the ‘Dash’ action, which is pretty close.
What can you do with the ready action?
The ready action cannot be used to postpone your entire turn, you can either move or use an action (decided when readied) such as attack (one attack, no extra attack), cast a spell (the slot is consumed when it is readied and it takes concentration), interact with objects, or perform some other action.
How does the readied action work in DND?
It takes up your reaction, so you can’t perform the readied action and an opportunity attack in the same combat round. The readied action happens when the trigger occurs, but any movement has to be done on your turn—unless your reaction is to move.
When to use ” I ready my bow attack “?
In your example, “I ready my bow attack for when I can see an enemy” so if they open the door and see an enemy, they can use their reaction to shoot the bow. As others have said, you can’t ready your action so you can move and attack, it has to be “I ready my sword attack for when an enemy comes within range”.
