I've just had an idea so what if Arkamsalem intentionally curses people with different variations or form of them to suite its own agenda at key moments or points so either the curses appears justified say as punishment in Zerefs case towards the tabbo or make it seem that the curse is caused by something else so it seems natural or as a side affect of something else such as Mavis using the spell Law for example.
