As you spend 10 minutes to cast this spell, while holding the statuette, choose a spell using 2 mana or less that you can cast, that has a casting time of two actions, an action, or 1 reaction, and that can target you. 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.
The contingent spell takes effect immediately after the circumstance is met for the first time, whether or not you want it to, 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.
