Astral Hammer of Celestial Fire

A Celestial Warhammer that fell from the stars, causing glory in its wake.

You gain a +3 bonus to attack rolls and damage rolls made with this magic weapon. The weapon deals an extra 1d8 Radiant and Fire damage to any creature it hits.

The weapon has the following additional properties.

Celestial Forge. You gain a 1d6 bonus to smithing checks made using this weapon. Additionally, when you craft a weapon, it deals an extra 1d10 Radiant Damage. 

If you craft a Armour or shield, it gains resistance to Radiant Damage and Necrotic Damage.

Astral Divine Strike. You can use an Action to strike the Astral hammer to the ground, consuming a charge. Doing so causes a pillar of Flame and Light to appear in 10ft radius with a height of 100ft.

Any creature, aside from you,  inside of the Astral pillar must succeed a DC 20 Dexterity Saving throw or take 5d6 Radiant and 5d6 Fire damage. A creature that succeeds takes half damage. The Astral pillar then Fizzles away.

You regain 1 expended charge at dawn.

Proficiency with a Warhammer allows you to add your proficiency bonus to the attack roll for any attack you make with it.
