Whip of Erebos’ Agent

Weapon (whip), artifact (requires attunement by a creature opposed to the undead) Price: 100,000-250,000 gp | high sentimentality

This whip was taken from an agent of Erebos and echoes the properties of Mastix, the whip with endless reach possessed by the god of death himself. It has a leather handle from which hang small ivory carvings of skulls, and the lash twinkles with bleak and sorrowful starlight. With the whip in hand, you sense the presence of undead creatures when they come within 120 feet of you. You gain a +3 bonus to attack and damage rolls made against undead creatures with this magic weapon.

Paid

You gain the following attributes when using the weapon:

Control the Grave. You can use an action to lash the whip against the corpse of a creature that died within the last hour. The creature returns to life for 2 turns with maximum hit points and the stats it had in life. The creature shares your initiative order but takes its turn after yours and is considered a creature under your control. The creature uses its full movement and actions each turn to approach and attack a target you choose on your turn. When the creature drops to 0 hit points or 2 turns pass after the creature’s revival, the creature’s body evaporates into black smoke and its soul passes on to its journey to the Underworld, leaving no corpse behind and becoming unable to be raised from the dead.

Life Link. When you’re hit by an attack, you can use your reaction to distribute the damage you’d take from being hit to up to two creatures you control instead. If the damage exceeds the remaining hit points of the creatures you designate, you suffer the excess damage.

No Escape. If you raise creatures from the dead using any ability except the ones granted by this whip, Erebos conveys his displeasure by causing you to lose attunement to the whip. You can’t attune to the whip again unless you placate Erebos with a suitable sacrificial offering.

Overpaid

Once a day for the first ten days after you attune to the whip, you may cast the commune spell without requiring material components to contact Erebos.

Destroying the Whip of Erebos

You can’t easily unmake a weapon blessed by the gods. There are only two ways to destroy such a weapon: melt it down in Purphoros’ forge, which resides within Mount Velus, or slay the god who blessed the weapon—in this case, Erebos—to transform the weapon into a nonmagical item that is susceptible to all methods of destruction.
