Slicing - Weapon
While this weapon may not deal much damage on a particular hit, the wounds it inflicts are instead meant to slowly bleed the enemy dry. This weapon deals -1 damage on damage rolls, but creatures damaged by it begin bleeding. A bleeding creature is dealt 1 damage at the start of their turn for each time they are damaged by this weapon. All bleeding is stopped by a creature using their action to perform a successful DC10 Wis (Medicine) check or by receiving magical healing. Undead, elementals and constructs are immune to this effect.
Versatile - Weapon
You may use this weapon either one-handed or two-handed. If you choose to use it two-handed, use the damage die in parentheses when calculating damage.
