Part of the trouble is that mana doesn't scale as much as other things... But that's probably why these glyphs aren't canon, anyway:
Burninate - Applies one Burn stack. (Cost: 2?)
Burninator - Set all visible monsters to maximum burn stacks. (Cost: 10? 12? Unbalanceable?)
Corrode - Applies one level of Corrosion. (Cost: 8?)
Weaken - Applies one level of Weakness. (Cost: 3-4?)
Mana Burn - Magical Strike enemy does 50% damage and the damage is physical. Lasts for one hit. (Cost: 5?)
Curse - Applies a stack of Curse to an enemy. A Cursed enemy has half of its usual resistances, lasting for one hit per Curse stack. (Cost: 6?)
Study - +1 XP. (Cost: 5?)
Pray - +1 Piety (Cost: 3?)
Convert the Aether - +5 CP (Cost: 10?)
