This spell is identical with chill metal except that it makes
metal warm, hot (1d4 points of fire damage), and searing (2d4
points of fire damage) instead of cold, icy, and freezing.
Enchanted metal gets a saving throw to resist. Just as damage
from chill metal negates fire damage, so damage from heat metal
negates cold damage on a one-for-one basis. If cast underwater,
heat metal deals half damage and boils the surrounding water.
Heat metal counters and dispels chill metal.
