Crown of the Sunken King

The Crown of the Sunken King is a helm that grants one point to each of these stats: Endurance, Strength, Dexterity, Intelligence, and Faith. However, the crown lowers one point from each of Vigor and Vitality. The Crown can be collected after defeating Sinh.

Cave of the Dead

Brightbug x 2 at Cave of the Dead, Dark Souls 2: SotFS

Start from the Priestess' Chamber bonfire. Drop down and enter the Cave of the Dead. Collect Brightbug x 2 in the area filled with statues that spit a substance causing your petrify metre to build up. Equip the Ash Knuckle Ring to boost your petrification resistance.

Graverobber, Varg, and Cerah

SL1 Graverobber, Varg, and Cerah, Dark Souls 2: SotFS

A gank boss where you fight a trio of NPCs. Buff your weapon with lightning. Your priority should be to get rid of Cerah as quickly as possible, i.e. the NPC who shoots with a great bow. The running two-handed R1 of the Greatsword is useful for dealing with Cerah. Each of the remaining two NPCs can be handled similarly or you might prefer to use the two-handed R2 of the Old Knight Mace. There's a ledge behind a patch of stalagmite. Standing on this ledge would allow you to cheese two of the NPCs. Use the two-handed R1 of the Greatsword to cheese the NPCs. Ensure that Cerah is already defeated, otherwise Cerah would snipe you with great arrows.

Defeat the trio and exit the arena to collect the Flower Skirt. The skirt raises your Vigor by two points and Endurance by one point.

Dragon's Rest

Start from the Sanctum Walk bonfire and cross the bridge that was activated by the Dragon Stone. Drop down to an area where a Drakeblood Knight is found in a room with Crystal Lizard x 4. The lizards drop a Titanite Slab and Titanite Chunk x 3, among other upgrade materials. Locate the Sanctum Interior bonfire, which is hidden behind an illusory wall.

Elana, the Squalid Queen

SL1 Elana, the Squalid Queen, Dark Souls 2: SotFS

Use a fast weapon and buff it with Aromatic Ooze. You want Elana to summon a bunch of skeletons because the skeletons are easily killed. Use the Mace to get rid of all skeletons, then focus on Elana. You must defeat Elana to unlock the fight against Sinh.

Sinh, the Slumbering Dragon

SL1 Sinh, the Slumbering Dragon, Dark Souls 2: SotFS

This boss is weak against lightning. Bring plenty of Repair Powder. Aim to hit the head and neck of the boss. Hitting any other part of Sinh's body would drastically degrade your weapon. Don't equip the Bracing Knuckle Ring+2 because you're better off equipping a ring that boosts your stamina recovery or damage output. Have some Poison Moss ready in case you get poisoned. Position your character in front of the boss, stand some distance from the head, bait the fire breath, and run in to hit the head or neck.

Defeat Sinh and collect the Crown of the Sunken King.
