Discordant Ruin (Patreon)

Weapon (warhammer), legendary (requires attunement)

A once grand weapon of a renowned titan slayer now ruined by draconic breath, seeping matching energy from its melted core. You gain a +3 bonus to attack and damage rolls made with this magic weapon. This weapon has 6 charges and regains all charges after a long rest.

Draconic Contamination. The head of this hammer is seared by the essence of a chromatic, gem or metallic dragon's breath. When you hit with an attack roll using this magic weapon, the target takes an extra 1d8 damage of the same type as the breath infused in the head of this hammer.

Echoing Impact. While holding this weapon you can spend a charge as a bonus action to have it begin to reverberate with tremendous force. Until the start of your next turn, when you hit a target with this weapon the target takes an extra 1d8 thunder damage for each size larger than you as shockwaves pulse through it. While this property is active, if you score a critical hit against a creature, it must succeed on a DC 20 Constitution saving throw or become stunned until the start of your next turn.

Contaminant Eruption. As an action you can spend 3 charges to slam this hammer upon the ground to create a 30-foot radius sphere of dragonic energy centered on you. Each other creature in the area must make a DC 17 Dexterity saving throw. A creature takes 6d8 damage on a failed save, or half as much damage on a successful one. The type of damage is the same type listed in the Draconic Contamination property.

The hammer of the Lord Knight Averill, once a national treasure and testament to the might of its owner. Resplendent and beautiful, hammer and wielder together marched forward in service of their people. Capable of felling giants, titans, and mountains alike, this storied weapon paved the way for a nation and a people with Averill himself at the tip of the spear. And now? It is but a morbid trophy, scarred from its bout with the dragon that slew Averill as easily as it had hundreds of challengers before. It sits amidst a mountain of glittering spoils, serving as a cruel monument to the draconic tyrant forever more.
