Grants a razor familiar that orbits Isaac. Enemies that touch the razor take damage equal to 20% of Isaac's tear damage per tick or 300% of Isaac's damage per second ( 150% of Isaac's damage per second) and start to bleed.
Bleeding enemies take damage equal to 10% of their maximum health every 5 seconds. Bosses cannot bleed and won't take any damage from the razor.
Bleeding enemies repeatedly take 2.8 + (floor * 0.3) damage based on how quickly they move; the faster the enemy, the more damage they take. While moving, a bleeding enemy leaves behind red creep that can damage other enemies.
The razor does not block enemy shots.

Notes
