Heal: Only applies to out-of-game injuries. Allows the Cats to heal any minor injuries that characters obtain, or slow bleeding enough to get a quest for larger ones.
Time: Slow, Haste, and Stop! Wears off after anywhere between thirty seconds and five minutes.
Space: Mid-range teleportation. Only one person (themselves or another) can be moved at any one time. The Cat doesn't have to be able to see the area they’re teleporting to, but they do have to be able to picture it clearly.
Paralysis: Paralysis lasts between thirty seconds and five minutes, and can affect anything from individual limbs or digits to the whole body. Organs cannot be paralyzed.
Sleep: Can knock the target into a light doze, or render them so unconscious a foghorn wouldn't wake them. Can theoretically last for up to two hours.
Shield: Shields can last up to ten minutes. The larger and stronger they are, the less time they'll last.
MP Drain: Pulls the plug on the target's own magical reserves. Each cast can deplete a maximum of 50%, and takes about twenty seconds.

Cats can only use one spell at a time, but can swap between the different abilities by concentrating hard for at least one IC minute. If something happens to break that concentration, the swap will fail. There is a limit of ten casts per day. The tenth cast will be exhausting, and trying to exceed this limit will both fail and result in the Cat knocking themselves out. Switching to a new power won't cost anything, but it also won't grant them additional casts.
