The Reanimator can heal themselves for 80hp with a level 1 spell slot.

The new Reanimator has come out and while it seems a bit weak it also seems very tough. The reanimated companion can do many things but at level 15 it becomes a level 1 healing spell that heals 80 hp. The ability life transfer allows a reanimator to sacrifice their companion to transfer its hit points to the artificer. Then with a single level 1 spell slot resummon another companion and do it again. Plus if the companion is damaged the Reanimator can heal it with a lightning damage cantrip like lightning lure. Plus the death explosion damages nearby enemies. That is impressive in my opinion.
