Arch Magi's Contingency

Choose two spells of 9th level or lower that you can cast, that have a casting time of 1 action, and that can target you. You cast the two spells--called the contingent spells--as part of casting Arch Magi's contingency, expending only one 9th level spell slot and two spell slots of your choosing between levels 7th and 8th, 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 spells.

The contingent spells take effect immediately after the circumstance is met for the first time, whether or not you want it to, and then Arch Magi's contingency ends.

The contingent spells take effect on all whom the spell designates as a viable target, as long as one of the targets is yourself.  You can use only one Arch Magi's contingency spell at a time.

If you cast this spell again, the effect of another Arch Magi's contingency spell on you ends. Also, Arch Magi's contingency does not end on you if its material component is ever not on your person, instead the spell only ends if the contingent requirement is fulfilled or the material component is destroyed.
