Wand of Watoomb

The Wand of Watoomb is a nigh-unbeatable magical wand.

Passive Abilities
Charging: This artifact has a certain amount of charges that must then be recharged according to the specifications listed below. Legendary Magic: Gives the user 5 extra Sorcerer points so long as they wear the artifact.
 * 20 Charges, must recharge through a ritual with the Crystal of Kadavus or through Absorb.

God-Slayer: This weapon ignores all immunities and resistances when dealing damage.

Magic Conduit: Magic may be cast through the artifact instead of a normal focus.

Power Immune: The artifact is immune to all effects and powers not cast by the wielder. This doesn't extend immunity to the wielder. It cannot be broken, transported (seperately from the wielder), or altered by an opponent.

Active Abilities
Empower Wand: As an action, you may empower the Wand of Watoomb with an aspect of its power, granting it 7d8 + Wisdom modifier in Radiant damage, along with one of these effects. Empower lasts for 1 minute and costs 5 charges per hit. Absorb: When hit by a magical weapon or spell, you may make a DC 20 Charisma save as a reaction. On a success, the artifact absorbs the magical damage dealt, recharging it. Should the damage exceed the maximum amount of charges or overcharge the Wand, you must use this energy to either heal yourself, redirect it as a 120 foot long, 2 foot wide beam, dealing equivalent damage; or form a magical barrier with a radius of 5 feet, an AC of 18, and hitpoints equal to the damage absorbed. On a fail, you take the damage as normal. This requires at least 5 charges to be present in the Wand.
