Vorell’s Spell Siphon

If a creature is casting a 1st level spell or 2nd level spell, you may use your reaction to redirect and siphon the spell. Any material components required for the spell are consumed from the creature casting it and that creature loses a spell slot like normal. If you have siphoned a spell this way, you regain amount of hp equal to a d8 per spell level siphoned.

At Higher Levels. The level of spells that can be siphoned increases by 1 as well as the the amount of d8s healed by 1 if a 5th level slot is used. These increase by 1 for each level slot used above 5th.
