When you sees a creature within 30 feet drop to 0 hit points, you can use your reaction to channel the expended life essence and targets another creature it can see within 30 feet of itself. The target must succeed on a Constitution (DC = 13 or Spell casting save DC) saving throw or become poisoned for 1 minute. While poisoned in this way, the target takes 1d8 poison damage at the start of each of its turns and reduced speed by 5. The target can repeat the save at the end of each of its turns, ending the effect on itself on a success.

At Higher levels:1d8 poison damage and reduce movement speed by 5 ft per Spell slot level beyond level 1

NOTE: A poisoned creature has disadvantage on attack rolls and ability checks.

*Modifications of generic school mage stat blocks ability in Strixhaven for the 5 schools, can be added to NPC sheets to replace generic monster stat blocks suggested.
