Sage LaTorra about creating new Spells in Game:
Wizard: I’m going to use this place of power to craft a new spell.
GM: Okay, tell me about the spell
Wizard: Well, it’s a bolt of lightning from my fingertips that strikes the creature it hits dead and can never miss.
GM: Hmm, okay, well the best you can manage is a lesser version: a 5th level spell that does damage like a fireball to one creature and stuns them momentarily. Drawing on the place of power gives you the raw energy, but you’ll need a creature of electricity to aid you in the research. An elemental will be best, but even a few lightning-struck villagers will be fine.
