[Mad Biomancer] Mimicleaver (Patreon)

Weapon (any), uncommon (requires attunement)

Mimicleavers are biomantically infused weapons that can be momentarily awakened to deliver a surprise bite to your foe. Sometimes their appetite gets the better of them and they can’t be wrested from their quarry until they’re satiated. Wielders of mimicleavers usually carry around spare weapons, just in case.

On a hit, this magic weapon deals an additional 1d4 acid damage to the target.

Surprise! When you miss with a weapon attack using a mimicleaver, you can use your reaction to make a melee attack roll (+5 to hit) as the mimic tries to bite at the target. On a hit, the target takes 1d4 piercing damage and 1d4 acid damage.

The mimicleaver likes to pass judgement on the quality of what it chews. After you use the Surprise! feature, roll a d4; the higher the number, the more the mimicleaver enjoyed the taste.  On a 4, the mimicleaver latches on and tries to chew the creature; make one attack roll (+5 to hit) at the start of each of your turns (“no action required”), dealing 1d4 piercing and 1d4 acid damage on a hit. A creature can remove the mimicleaver by using its action to make a successful DC 13 Strength check, or it naturally detaches after 1 minute. After the mimicleaver detaches, it is satiated and enters in a state of hibernation, you can no longer use Surprise! until the next dawn.

Rare variant. Increase the attack modifier to +7, the acid damage to 1d6, the d4 to a d6, and the Strength check DC to 15. The mimicleaver latches on on a result of 6 instead of 4.

Very rare variant. Increase the attack modifier to +9, the acid damage to 1d8, the d4 to a d8, and the Strength check DC to 17. The mimicleaver latches on on a result of 8, instead of 4.
