Effects

• Spawns a special set of spikes in the Devil Room. They deal 1 full heart of damage per use.

Rewards

Chance	Reward
35%	Nothing
33%	+ 0.5 damage
15%	6 pennies
10%	2 Black Hearts
5%	A random Devil Room item
2%	Transform into Leviathan

Notes

• The spikes will not appear if the current floor's Devil Room was entered before picking up Sanguine Bond.
• The spikes will deal damage to enemies that walk or fly over them, including Krampus.

Synergies

• Goat Head + Scapular: The spikes generated by Sanguine Bond can be farmed infinitely.
  • Quitting and reloading the game will also reset the soul heart regeneration provided by Scapular, thus negating the need for Goat Head
• Keeper / Tainted Keeper / Strawman: The pennies that are spawned when stepping on the spikes can be used to heal Keeper and infinitely farm rewards.
• Placenta: With a lot of time, the spikes can be farmed infinitely.
• Portable Slot: The pennies that are spawned can be gambled to give hearts, allowing more uses.
• The Wafer / Percs: Hearts will last twice as long, allowing more uses. Further uses may be obtained by sacrificing the black hearts given, and any hearts added from devil room items.

Trivia

• This is possibly a reference to the card of the same name from Magic: the Gathering card game.
