Molten Penny is a trinket added in the initial release of Fiend Folio.

Effects

• Picking up a Penny has a 2% chance to activate the Smelter effect, destroying Isaac's currently held trinket and applying its effects permanently.
  • Isaac's luck increases the chance to smelt trinkets by 0.5% for each point of luck; at 196 luck, this reaches a guaranteed 100% chance.
  • Different types of coins can grant additional flat bonuses to the chance:
    • Lucky Pennies and Nickels add 3%
    • Dimes add 6%
    • All other types of coins will increase the chance based directly on its value.
  • Molten Penny will have a guaranteed chance to smelt a trinket if 30 coins have been picked up without the effect activating. The type of coin doesn't influence this number.

Notes

• Molten Penny needs to be smelted first to be able to smelt other trinkets — unless Isaac is allowed to hold two Trinkets at once, in order to hold one other trinket with Molten Penny.

Interactions

• Trinket Multipliers: The total luck and coin bonus chance is multiplied by 1 + 0.25 × (Trinket Multiplier − 1). The base 2% activation chance is unchanged.
• Belly Button / Mom's Purse: If holding two trinkets, both of them will be smelted at once.
• Azurite Spindown: Using Azurite Spindown on Molten Penny rerolls it into GMO Penny.

Trivia

• The inspiration for Molten Penny's effect came from GMO Penny, based on how GMO Penny has a chance to activate the Gulp! pill effect resulting in gulping itself and thus potentially gulp other trinkets.
