As you spend 10 minutes to cast this spell, choose a cantrip that you can cast. You cast that spell—called the contingent spell—as part of casting contingency, expending mana for both, but the contingent spell doesn’t come into effect. Instead, it takes effect when a certain circumstance occurs. You describe that circumstance when you cast the two spells. For example, a contingency cast with aquatic adaptation might stipulate that aquatic adaptation comes into effect when you are engulfed in water or a similar liquid. You must make any decisions for the spell when you cast contingency, such as choosing fins or gills for aquatic adaptation.

The contingent spell takes effect immediately after the circumstance is met for the first time and then contingency ends.

The contingent spell takes effect only on you, even if it can normally target others. You can use only one contingency spell at a time. If you cast this spell again, the effect of another contingency spell on you ends.

Augment

The contingent spell can sue 1 additional mana for each additional mana expended. The contingent spell must have a casting time of two actions, an action, or 1 reaction.
