About FotF 2e, Magic-User Invocations
Dragonlance 5th Age, Saga System, used a kind of point buy feature to design spells on the fly. It strikes me as similar to what’s proposed on the 2e rules, so I’d like to share this (maybe it shines some light on Jason Lutes design and playtests, but I believe he must be familiar with this anyway).
Spells there have 5 components: invocation time (taking more time uses less points), range, duration, area of effect (including a kind of subtable for groups, physical area, and time for divination purposes), and effect.
The only thing different here is the invocation time, I believe.
