Indefinite

Indefinite is a class of duration used in Sorcery. Pg 8's "Maintaining Spells" indicates this means so long as 1 FP per minute is spent.
It's unclear if that means they can't be cancelled earlier.
Minimum Duration of less than 1 hour is worth -0% but seems to be how spells normally operate: they cost 1 FP to prematurely terminate prior to the expiration of a maintenance period.
