Just a small charm suggestion is to add homenum revelio, a spell most known for its use by Hermione in the deathly hallows at grimmauld place. The charm reavels nearby people and my idea is to add it to potterworld. How i believe this would work is that you cast the spell and it puts a spectral effect on every nearby players, mobs and npc, or just one or two of them. Maybe have it upgraded in a spell tree to last longer and over a bigger area. Idk I think it would be a fun and usefull spell.
