Warhammer Fantasy

You touch a willing character and they fall into a hibernation state. This state persists for many months, until the solstice or equinox after the next (that is, the remainder of the current season, plus the full season after that). During this period of slumber, the character need not eat or drink. Any diseases, poisons, or other similar afflictions the character endures are interrupted for the duration. No further damage or symptoms accrue from them, though any penalties or other maladies already in effect continue while the character hibernates. (A progressive poison would not continue to get worse.) Natural healing, however, does occur. The recipient of this spell cannot be woken by normal means; the caster must will a premature awakening. They may also cast this spell on themselves. In the event that they do, they may -- at their option -- designate one other individual, who must be present when casting the spell, who may wake them before the spell's natural duration.
