Choose a spell of 5th level or lower that you can cast, that has a casting time of 1 action, and that can target you.

You cast that spell—called the contingent spell—as part of casting contingency, expending spell slots 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 water breathing might stipulate that water breathing 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.
• Also, contingency ends on you if its material component is ever not on your person.

Meticulously prepared, a bespoke bone statue of yourself, adorned with meticulously chosen gem eyes, now serves its purpose. While the jeweler once scoffed at the ostentatious creation, it proves invaluable as the embodiment of your foresight and cunning.

I Cast Spell Contingency
In the cryptic tongue of magic, I commune with a costly statue bearing my visage. Twin spells are woven—one upon the likeness, a patient directive: "Wait. Unleash this when my described trigger occurs." The statue, silent yet knowing, ensures the reserved spell unfolds precisely, validating the intricate dialogue's purpose.
