Mara

You couple one or more spells to cast simultaneously at a later time. For each spell you couple in this way, this spell adds a cumulative cost in MP to cast: coupling two spells costs 2 MP plus the cost of the spells involved; coupling 3 spells costs an additional 5 MP; coupling four costs an additional 9 MP. The spells cast in contingency have duration, targets, and area of effect equal to MP cost at which they were coupled. This spell cannot be coupled in this way.

Through sheer force of will, you disbelieve the existence of a real, mundane object, rendering it incapable of affecting you. For each object in the area of effect you choose to disbelieve, its wielder (if any) must make an opposed spell check against you to affect you. If you fail, the object affects you normally. This check must be made each time the disbelieved object interacts with you.

You conjure into existence a pair of manacles for each MP spent. The manacles must be shackled to a victim manually to have effect (the victim is not entitled to a spell check if the manacles are successfully attached); afterwards, the victim cannot remove them, no matter their strength. The manacles are invulnerable to all forms of mundane damage, and will adjust their shape to match the limbs of the victim to which they are affixed. You can undo the shackles with a command word.

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.
