Dark Souls II: Scholar of the First Sin

Shoot him with one of the Ballista set-pieces in his arena. Although aiming will be difficult, a single shot will take out almost all his health.

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.

Straid of Olaphis is located in Lost Bastille after the Ruin Sentinels near the bridge to Sinner's Rise. Initially he is petrified, surrounded by five rupturing hollows that deal physical damage. Straid will be at the opened jail cell. A Fragrant Branch of Yore is required to cure him. One can be obtained at the bottom of The Gutter, immediately before the fog gate to Black Gulch. After you cure him, he will sell the spells as well as offer you trading Boss soul services.

At Shrine of Amana, go to the last hut before the entrance to the last bonfire. At Rhoy's Resting Place, exit the back door and look down to your right for a stone. Stand in front of the stone with the opening to Rhoy's cave over the back of your left shoulder. Walk straight ahead with some type of light to find the chest containing the Fire Tempest Pyromancy.

There's a coffin in Things Betwix in the sand circle where the fat big guy stand. If you enter in that coffin your character will swap its gender with the major facial details.
