- Casting Time: 1 reaction; Verbal
- Trigger: a spell or magical effect that deals damage is cast within range
- Range: 60 feet
- Target: the triggering effect
You transform the triggering spell into an illusory version of itself. Treat this as a dispel attempt with advantage, except that if the dispel attempt is successful, any creatures that would be damaged by the spell instead take only half as much damage, applied after results from an attack or save. Shadow Siphon is on the Arcane and Occult Spell Lists.
