Pierre

You hijack your target's senses so as to supply false sensory input to them. You may switch between the five senses round to round. Each round you may falsify one aspect of the victim's perception at a time: make salt taste like sugar; a thief appear as a priest; a scream sound like a whisper; or a burning sensation feel like cool water (as examples).

You heal 1 HP per MP spent, split among as many targets in the area of effect as desired. Any status effects caused by minor perils on the target(s) are cured. This spell does not heal wounds or targets on death's door. (If an Undead creature is affected by this spell, they are entitled to a spell check and receive 1 HP damage per MP spent, bypassing soak.)

You call upon the aid of a magical patron to bestow a curse upon your target. They are not entitled to a spell check. The target gains disadvantage on the next roll of your choosing (initiative, a specific weapon attack roll, a specific skill, but not attributes in general). This effect is not ongoing, and ends after the roll is made. You may cast this spell as a reaction once during the round, in addition to any other action you take.

For the duration of the spell, you may make an opposed check against any target aware of your existence in the area of effect. If you succeed, they lose awareness of your existence and you are considered stealthed with your spell check serving as the stealth score. You are still very real, however; any direct interaction with the target will immediately reveal you.

You utter a magic word at your targets. If they can hear it, they are wracked with crippling pain for the duration of the spell. Such victims are stunned and their movement rate becomes 0. This spell lasts as long as you concentrate, otherwise their pain ends.
