Hi! Your game sounds fun! I have a few questions about powers.

My oc's magic feeds off the world's residual magical energy. It does damage the world over time but it would take hundreds of years to do any serious damage. Do I need to nerf this ability or is it ok as is?

Another possible world interfering ability is Altair's ability to shadow jump. In his canon he can use shadows to travel to a magical dimension between worlds. He uses this ability to teleport between shadows. If Altair tried to use his ability to slip between dimensions here what would happen? What would he see? Or would he be instantly pulled back into Andovale?
