Light of Fo
Only a Priest of Fo can cast this spell
Light of Fo is an area of effect spell given to priests of Fo at 33 faith.
It heals 5 wounds for a total of 1/5th of the spell's power, and automatically targets the most severe wounds. A minimum of 6-7 damage per wound will be healed.
Healing spells and enchantments grant the healed player a healing resistance effect. This effect is applied based on how much health is healed, and will reduce all further healing on the target from any healing spells or enchantments. This includes healing spells as well as weapon enchantments that heal the player, such as Life transfer.
The maximum duration of healing resistance is approximately 20 minutes, and the reduction scales linearly from that mark. For example, if you have 10 minutes of healing resistance remaining, you will receive heals at 50% normal effectiveness.
