Magic Weapon (Greatsword), Very Rare, requires attunement
Magic Weapon. Soulthorn has a +2 to all attack and damage rolls made with it. It deals an additional die of damage on a hit. It adds its +2 bonus to the Graze damage on a miss.
Soulthorn.When you reduce a creature to 0 hp or hit a creature at 0 hp with Soulthorn, it is immediately slain. Soulthorn gains a +1 bonus to damage rolls for every creature it has slain that day, which also applies to the Graze. The bonus resets at dawn.
A creature slain this way can be revived and has a -1 to all checks until the bonus resets.
Curse: Hunger for Death. Soulthorn urges its killer to kill and claim the power of souls for it to grow stronger. If a creature in combat within 60ft is low on health (25% of max health or less), the user must make a DC 17 Wisdom saving throw at the start of their turn or be forced to attack that creature at full force. The DC increases by 1 for every soul partially claimed by this weapon.
