The Tempest Domain cleric's Thunderbolt Strike feature (PHB, p. 62) says:
At 6th level, when you deal lightning damage to a Large or smaller creature, you can also push it up to 10 feet away from you.
I envision the Thunderbolt Strike as throwing the target creature away from it, not gently pushing it away. I mean, lightning is an instantaneous thing, and 10 feet is more than just losing your balance.
The Thunderbolt Strike feature of a Tempest cleric leaves me with many questions. For instance, if a monster is able to make a multiattack consisting of 2 claw attacks and then a bite, and it hits me with its first attack, I can use Wrath of Storm as a reaction to deal lightning damage to it, and thereby blast the creature back 10 feet using Thunderbolt Strike.
If the monster does not have 10 feet of movement left after being pushed, does it lose its other 2 attacks against me (if no other targets are in range of it)? Or does it get to make all 3 attacks before it is blasted away from me?
