HackMaster 4.0: A Day in The Life and Level Advancement

[Kersus]

Sames as I got on the Kenzerco forums, except that one said as long as one recast the spell, before it expires every day, one can keep it up.  

And can it be maintained by a Permanency spell?

I'd probably say the spell would have to expire before it was recast however while level limits serve a great purpose, I believe the original thought was that there would always be exceptions like Hobbit Bards (1e) and such generally requiring great quests for items of power that would allow such exceptional characters. If a player wants to put in the work, I'd let them take on an exception although I'd generally also require a quirk to come into play. Anyone who spends so much time trying to be 'different' will also be quirky.

One could also maintain a balance where such creatures become the target of new enemies. Archmage who comes for those who defy natural laws.
