Survival of the Fittest

*Mundane tier (Advanced Fusion), primary material: Tin*

**Weapons: longsword, scimitar**

Requires Attuning

Infused with the primal might of apex predators, this weapon bestows its wielder with savagery and power rivaling that of even the most feared monsters. When this weapon is used to make an attack, it grants a +2 bonus to hit and a +5 bonus to damage. On a hit, it deals an extra 6d10 slashing damage and another 5d8 bludgeoning or piercing weapon, as chosen by the attuned wielder. Regardless of which type of damage this weapon deals, the target is always vulnerable to that damage, ignoring whatever resistance or immunities the creature might normally have.

When this weapon lowers a living (non-undead, non-construct, non-elemental) creature to 0HP, that creature is killed instantly and the attuned wielder is granted a rush of power similar to that felt by an apex predator who had just devoured a fresh kill. This ability, named **Victorious Feast**, buffs the wielder for a number of rounds equal to the slain creature's CR (minimum of 1 round), allowing the attuned wielder to enjoy the following benefits:

* Recover 1 Hit Die of HP at the start of each turn
* Gain immunity against necrotic damage
* Gain a +3 bonus to attack rolls and a +2 bonus to damage rolls
* Cannot suffer disadvantage on attack rolls
* Can make one additional attack per Attack action, and
* Gain advantage on all saving throws

The attuned creature cannot benefit from this condition more than once per 24 hours. The attuned creature can choose whether or not to activate this ability upon a kill, unless they have been "starved" for a kill, as detailed below.

Despite the multitude of benefits bestowed upon the wielder, this weapon unfortunately also comes with a slew of problematic penalties. Namely, the laziness that is typical among apex predators. After benefiting from the effects of Victorious Feast, the wielder becomes "satiated" for 4 hours, during which time they are effectively afflicted with the effects of the Slow spell for the duration, and this weapon becomes incapable of dealing damage for the duration. This penalty cannot be reduced or removed by any other means other than waiting for it to wear off. The attuned creature is also afflicted with a curse-like effect that causes them to lust after bloodshed. If the attuned creature spends over 5 days without killing another creature, they become "starved" for kills and will starts to lose 1 point of Wisdom each day during midnight. Should this effect reduce the attuned creature's Wisdom to 0, it will be seized by a bout of bloodlust-driven madness that forces them to viciously attack the closest living creature, regardless of alignment, until it is killed. The Wisdom score reduced this way are restored once the attuned creature scores a kill, but otherwise cannot be restored via any other method except the Wish spell. Should the attuned creature score a kill after it had started to lose Wisdom score, the Victorious Feast ability will be automatically activated after the first kill it scores, and once the ability's benefits wore off, the attuned creature will immediately fall unconscious for a number of hours equaling twice the killed creature's CR (minimum of 1 hour), during which they cannot be roused by any means short of a Wish spell.
