Rod of Ra

non-magical* melee Sacred weapon

This weapon’s damage is comprised entirely of Sacred.

*Though it may seem odd to describe a weapon that deals Sacred damage as non-magical, per the definition spelled out in the Player’s Handbook, this weapon fits the definition of “non-magical”.

Note: Undead suffer double damage from any source of Sacred energy, but Good-aligned Outsiders take no damage from Sacred power. If an attack with added Sacred damage wounds an Undead creature, only the Sacred portion of the damage is doubled.
