There are a few things to keep in mind when it comes to reactions in D&D. Reaction works as a way of letting players know what is happening on the battlefield, and how their characters might be affecting the situation. It can also be used as a way of giving players an idea of what is going on around them, or giving them something to do while they are waiting for something else to happen. Finally, reactions can also be used as a way of showing off your skills as a DM or game master.
