Light or Dark magic.

I agree – therefore, for the Necropolis, give them darkness, and for Haven, give them light; besides, light has the ability – Eternal Light, which works against darkness…. And as for the confrontation between Haven and Necropolis, it’s serious… there, the heroes, you could say, don’t let each other cast blessings on themselves or curses on the enemy…
P.S.: And no one forbids taking both light and darkness at the same time!
