Sometimes aiming is pretty hard.
- When you cast a cantrip that deals damage, you can select multiple targets and make a spell attack roll against each. You can target a number of creatures equal to the number of damage dice the cantrip deals, and split your damage dice up amongst your targets, to a minimum of 1 die of damage per target.
For example, if a cantrip deals 3d10 damage. You can choose to target three creatures and deal 1d10 damage to each creature, or you can target two creatures, dealing 1d10 damage to one creature and 2d10 damage to the other creature, or you can target one creature for 3d10 damage.
