Basic Magic guidelines for New Spells

[alphabetagamadelta]

I was looking at the Inventing New Spells guidelines in M14-15 and noticed there is nothing about increasing the concentration time required to cast. Should I just reduce the energy cost by 1 per extra second needed or is there other method you guys would recommend?

Not this. Reduced casting cost is potent and even 2 seconds is making the spell dubious in combat. You'd end up with inflated versions of non-combat spells lie a Ressurection variant that took 300 seconds more to cast.

I'm not sure I'd give anything for extra time to cast.
