This spell allows the shukenja to harden another against the pains and discomforts of heat, cold, fatigue, and hunger. Upon receiving the spell, the recipient is unaffected by normal heat or cold. One less point of damage per die is taken from magical fires and magical cold (ice, cold rays, and so on). Fatigue is banished as if
the character had slept for one hour for every level of the caster, although this does not allow spellcasters to regain spells. The effects of hunger and starvation are delayed until the spell has expired.
The material components of this spell are a piece of rice cake or dumpling, a scrap of cloth, a drop of water, and an owl's feather.
Notes: Common for oriental priests; otherwise, very rare.
