Vaalingrade
Legend
Because of how initiative works, that's not a given or even highly likely. The cleric casts Sad Healing, you get 6HP and get up. The orc goes and deals 10 damage, putting you back down. On your turn, you just get to make a death save and best case you do nothing, or best case, an ill-considered house rule to stop 'pop-up healing' (really a thiny veiled excuse to increase lethality) make it so this is strike 3 and you die.Of course, something has been accomplished, it will have given you one more round to get the killing blow in, or to run away, or even to occupy the boss one more round so that your friends can get away. And that's, for me, more than good enough for a bonus action.
The cleric could have picked their nose for similar effect and might have at least grossed the orc out.
