If you have an unpatched version of the game, this glitch still works. The engraved gauntlets give a chance for a normal hit to do the damage of a critical hit, like a backstab or riposte. Keep attacking until you trigger a critical hit from the gauntlets, then take off the gauntlets. Every hit will now become a critical, for a lot of damage. Will only work on PvE because you cannot play online without patching your game.

He is located in the second half of Brightstone Cove Tseldora, immediately after the Prowling Magnus and Congregation. Exit the church, then take a left to find a ladder. Climb it to find him up there.

Felkin is located at the very start of Huntsman's Corpse, before the first bonfire. You will need a base 8 Faith and Intelligence in order to gain access to him. If you have 20 Faith or Intelligence, he will also give you the Hexer Set and Sunset staff.

She is first found in the Tower of Flames after the regular Dragonrider. After exhausting her dialogue, she will move back to Majula at the device that unlocks the Huntsman's corpse on the way to Heide's Tower of Flames.
