Click Rule (Traps)

Whenever someone triggers a trap, I (The DM) say "Click". Before telling the party what the effects of the trap or asking them to make saves, Each member of the party will tell the DM what they are doing. Examples include "I hit the deck", "I throw up my shield", I cast misty step to move 30ft in the opposite direction". Depending what the player says, I (The DM) might offer advantage or disadvantage to the save or a variety of other benefits/penalties.
