Soulcraft Realms

Realm 2 - THE KINGDOM OF KNIVES
A world completely made of metal and sharp objects, even the very air itself tastes metallic. Blood is shed like money, as everything is unphased by bleeding wounds, and paintings are commonly made with blood instead of traditional paint. Giant steel spires pierce into the very sky itself, and the ground is covered in giant metal spikes. A merchant's stand, covered in golden and white feathers, stood off to the side of them, blood soaking the ground in front of it.
-New Laws-
Reinforced Bodies
Every single creature in the Kingdom of Knives is resistant to piercing and slashing damage.
Blood Tolls
A creature can use its action to slice itself on itself, dealing 1d4 damage to itself and gaining an amount of blood points equal to the damage dealt. Blood points last until a creature's next short or long rest and can be expended when dealing damage from a spell or attack to add the amount spent as damage. Additionally, some magic items, creatures, or objects in the Kingdom of Knives require blood points to perform specific tasks.
