Hallow Spell

The triggering spell deals no damage and the target of the spell instead regains hit points equal to the damage it would have dealt, ignoring resistances, immunities, and vulnerabilities. This spell cannot affect a spell attack that resulted in a critical hit. This spell only restores hit points to a single target if the original spell deals damage to multiple creatures and does not remove the damage from other creatures. If you cast this spell in response to a spell of 3rd-level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a success, you heal from this spell as normal, but on a failure, this spell fails and has no effect.   At Higher Levels. When you cast this spell using a higher level spell slot, you automatically effect a spell that is a level less than or equal to the level of the spell slot you used.
