Heal yourself about 50 hit points for about 50 spell points. Not as good as cure light wounds, but vastly better than waiting on natural regeneration.
One of the more self explanatory spells, and primarily used by magical and civilized background character.
The in game help reads:
No saving throw. Casting time: 2 rounds. Type of spell: heal spell. Affecting stats: wis. Cast type: heal. Spell point cost: 50. Not suprisingly, one of the first forms of magic that was perfected was the magic to heal one's own wounds.
