Tooth and Nail
Effects
- Every 6 seconds, Isaac turns to stone and sprouts spikes for 1 second. While Isaac is in this state, he is immune to damage and deals 40 contact damage.
- Isaac flashes white four times before turning to stone on the fourth flash. The first three flashes are accompanied by a "ticking" sound, the final one with the spike extension sound of a mimic chest.
- Unlike Gnawed Leaf, Isaac can still move and shoot tears.
Notes
Synergies
- Contact damage items work great with Tooth and Nail, such as Aries / Mom's Heels / The Virus for extra damage, Serpent's Kiss for Black Heart generation, Midas' Touch for coin generation etc.
- Damocles: As Isaac is invincible 1/6th of the time, with some luck, Tooth and Nail may save him from the falling sword.
- Kamikaze!: Allows usage without taking damage during invincibility.
- (The Lost) The Lost can use this item to prevent additional damage from occurring after losing the Holy Mantle (for example, exiting a (Curse Room) Curse Room after being hit), and it does not use up the Holy Mantle's 1-hit protection if it has not been lost.
