Resist Fire

This spell makes the caster, or any living creature the caster touches, completely immune to normal heat or fire. The spell also gives protection against magical or otherwise superior heat or fire such as the breath of a Mountain Dragon or the fireball spell. Specifically, the spell gives the protected creature a bonus of +3 on all saving throws against such effects, and reduces any damage suffered by half (so that for example a successful save vs. the fireball spell would reduce damage to just one-fourth normal, and even if the saving throw fails the protected creature only takes half damage).
