Finger!

Effect

• Spawns a floating finger familiar that can be aimed with the fire buttons in all directions.
  • The finger fires invisible spectral lasers, doing 10% of Isaac's Damage. The lasers fire 10 times per second and is not affected by Isaac's tear rate.
  • The lasers have thickness based on Isaac's Damage, making it easier to inflict damage on higher Damage.
  • While not being aimed with the fire buttons, the finger points in the direction of movement or downwards if standing still.
• (Removed in Repentance) The Finger!'s lasers can apply Isaac's Tear effects, which makes status effects trigger very often.
  • (Added in Repentance) The Finger!'s lasers do not apply Isaac's Tear effects.

Notes

• Finger! will fire in the exact direction it's pointed, meaning it can be fired diagonally, or at any angle, if using a controller - the same effect as Analog Stick.
• The beam can be used to destroy TNT (among other destructible obstacles).
• The Finger! can do damage to enemies through obstacles and other enemies.
• The Finger! does not do contact damage.
