After Clap (EFA - A)

Choose a creature you can see within range. This spell duplicates damage suffered by that creature during the previous round. Damage is precisely duplicated both in type and amount.

For example, in the round previous round an owlbear is hit for 14 slashing damage, 12 fire damage, and 42 piercing damage. When you cast afterclap, the owlbear takes a further 14 slashing damage, 12 fire damage, and 42 piercing damage from your afterclap
