This spell is a part of the Pyro Enchantment spell chain and is found in the Pyro Enchantment rune stone.
With this manipulation, you seek to pass on the burning power of the Sun to the business end of your or your ally's weapon. Whenever you or your ally attacks with their weapon, they would add to the damage the wielder's Runic Power + 1d10. Should the caster roll a natural 20 when casting, the caster will add their Arcana to the weapon as well. Should the caster roll a 1 however, the weapon will actually have a penalty of the wielder's Runic Power + 1d10. If the wielder of the weapon is of the Water element however, the Sun will refuse to attach its burning power to their weapon.
