+1 We should get a (low-DC) Dexterity Saving Throw to avoid any splash damage and/or a missed attack roll should result in the projectile hitting an off-target area on the ground. Perhaps 1 foot x (the difference in attack roll and AC) in a random direction.
Please allow us to use concentration spells effectively. I would actually use Bless if I knew that SH wouldn't lose it a turn from now due to unavoidable splash damage.
