Hammer of the Ram (Patreon)

Weapon (maul), rare (requires attunement)

This all-silver hammer carries a mighty force behind it with every swing. You gain a +1 bonus to attack and damage rolls made with this magic weapon. If the hammer hits an object that isn't being worn or carried, the hit is a critical hit.

The hammer has 3 charges and regains 1d3 expended charges daily at dawn. When you hit a target with the hammer, you can expend 1 to 3 of its charges to force the target to make a DC 15 Strength saving throw. For each charge expended, the target takes an extra 1d10 force damage and is pushed 5 feet away from you on a failed save. On a successful save, the target takes half as much force damage and isn't pushed.

Ring of the Ram. If you're also attuned to the ring of the ram, your bonus to attack and damage rolls with the hammer increases to +2, and the hammer's every swing creates a projection of the spectral ram from the ring. The ram lurches forward from the head of the hammer, effectively increasing your reach with the weapon by an additional 5 feet. In addition, the hammer and ring share a pool of charges: any charge you have with the ring can be used for the hammer's properties, and vice versa.

When you mess with the herd, you get the horns.
