Looks like CARE has some odd PERCEIVE messaging. I would expect it to tell me how much mana I need to provide for it.

You sense the Manifest Force spell surrounding you, which will last for about a roisan or until it has endured six more blows.
You feel a superficial manifestation of Redeemer's Pride upon you, which should last for about three roisaen.
You sense the Drums of the Snake spell upon you, which will last for about seven roisaen.
