"Isabelle shoots a ray straight from a B-movie that has healing/detox properties. Please do not ask how."
Cost: 5 MP
Source: Ganguro Isabelle - Starting skill.
Regeneration Ray is a spell that heals for an above average amount as well as removing the 
Poisoned status effect from a single ally..
With a low MP cost and it being usable outside battle, this spell will be used quite a bit. With only two enemies in Eric(a)'s Memories that can cause poison (Legion and Mothman), its poison removal aside, this spell will largely be used for its healing property as the only healing skill available in the dungeon. Used in combination with Negative Charge to restore Ganguro Isabelle's MP, this can be used as a free way of healing up while away from the healing points.
