Chain Contingency

Choose up to 3 spells of 8th level or lower that you can cast, that have a casting time of 1 action, and that can target you or another creature. You cast those spells--called the contingent spells--as part of casting chain contingency, expending spell slots for all spells chosen, but the contingent spells don't come into effect. Instead, they take effect when a certain circumstance occurs. You describe that circumstance when you cast the four spells. For example, a chain 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 spells take effect immediately after the circumstance is met for the first time, whether or not you want them to, and then chain contingency ends. The contingent spells take effect only on you, even if they can normally target others, unless the specified condition involves being attacked by another creature in which case you can choose the target to be the attacking creature instead for up to one of the contingent spells, as long as the attacker is within range of the contingent spell. If more then one contingent spell targets someone other then the original caster for any reason, the material component becomes overloaded as soon as the chosen circumstance occurs and explodes dealing 5d10 piercing damage to the caster, and all contingent spells fail to activate. You can use only one chain contingency spell at a time.

If you cast this spell again, the effect of another chain contingency spell on you ends. Also, chain contingency ends on you if its material component is ever not on your person.

Unlike the 6th level spell contingency, chain contingency will last until it is dispelled or triggered as long as the material component remains on the caster's person.
