Not a feature but a diff class
Ninja class would be cool
Like you get a katana as a starter weapon,
Passives are:2x speed like vampire, as a draw back you have 75 hp instead of 100,

Higher jump

Armor makes you slower

The more you are covered in blood the faster you go, capping at 2.9x speed
Price 75 or 100,im buying it either way even if its 300
