I'm an elemental magic user, and I've capped devitalize's mana. I'm ~1050 sorcery, and it's only a matter of time before devitalize stops training. I got Echoes of Aether and COTW, but once COTW is on a mob, subsequent casts don't train. There are no other non-signature tm/debil life magic scrolls. Almost every debil I cast keeps training with subsequent casts, but not COTW.

What do I do now? I can cast intermediate life mana aug/ward/util spells at full mana, but they don't train and backlash anyway even without using a symb! Is there just no option outside of research? If so, that is super dumb.
