[FF] The Gauntlet is a challenge in Fiend Folio, a mod for The Binding of Isaac.
There are no starting items defined for this challenge.
Note: this list does not include characters' default starting items.
Isaac starts with 3¢ and no bombs.
The challenge takes place in a single custom-made stage whose goal is to defeat every single boss and mini-boss added in Fiend Folio, with the exception of Hermit.
The challenge consists of multiple sections with a unique boss, each featuring a hub area that offers items and consumables for purchase.
Stage paths are blocked with Colored Locks, the only way to unlock them being by defeating bosses, which each drop a Colored Puzzle Key corresponding to these locks, in addition to 7 Pennies.
Entering a section causes the previous section's door to be permanently sealed.
