Contingency

Source contingency

You can cast this spell on yourself or another willing creature as if the spell had a range of touch. A companion spell placed on another creature must be a spell from you, not from the creature, and affects that creature when triggered. The target can have only one contingency spell upon it at a time unless it also knows mythic contingency. The number of companion spells you can have on yourself is equal to 1 + half your tier.

Augmented (5th): If you expend two uses of mythic power, the casting time changes to 1 full round plus the casting time of the companion spell, but the duration of mythic contingency decreases to 1 hour per level or until discharged.
