Very Large Ember

The Very Large Ember allows Andre to ascend various weapons from +10 to +11. For example, give the Very Large Ember to Andre and he would be able to ascend your Reinforced Club+10 to a Reinforced Club+11. You require a few Titanite Chunks to upgrade the weapon to +14 and a Titanite Slab to attain the maximum level of +15.

Upper Blighttown

56. Location of Power Within, Dark Souls: Remastered

Generally, this area is not worth exploring save for collecting the pyromancy Power Within. A rule for the current SL1 run is to not use any pyromancy against bosses. This includes Power Within as well. In case you plan on using Power Within in subsequent SL1 runs, e.g. an SL1 run in NG+1 and beyond, now is a good time to grab the pyromancy. Start from the Depths bonfire and use the Blighttown Key to access upper Blighttown. Head on down to the Parasitic Wall Hugger, kill the creature, and grab the shiny underneath.

Anor Londo

57. Anor Londo: Titanite Chunk, Dark Souls: Remastered

Before you have access to unflooded New Londo Ruins, the Royal Sentinel x 2 found in front of the arena of Ornstein and Smough are your best source of Titanite Chunks. You should have farmed these enemies prior to defeating Ornstein and Smough by summoning Solaire to help you farm. It is a nightmare fighting the Royal Sentinel x 2 and the nearby Silver Knight by yourself.

But do not despair. A Titanite Chunk is available to be collected. From the Chamber of the Princess bonfire, find the Giant Blacksmith. From his location, you should see a balcony at the edge of which is a shiny. That is a Titanite Chunk.

Darkroot Garden

Sooner or later you would need access to New Londo Ruins to fight the Four Kings. You require two items to unlock the boss fight:

• Lordvessel. You should already have this item after defeating Ornstein and Smough, and exhausting the dialogue of Gwynevere.
• Covenant of Artorias. This ring is dropped by Sif, a boss at Darkroot Garden.

Let's grab the second item.

Great Grey Wolf Sif

58. SL1 Great Grey Wolf Sif, Dark Souls: Remastered

Sif is weak against fire. Two-hand your Fire Reinforced Club+10. If you have a Chaos Reinforced Club+4, use that instead and have at least 10 soft Humanities. Enter the arena and interact with the massive sword in front of a gravestone to initiate the fight. Position your character underneath the boss to avoid its horizontal swipes. R1 or R2 a hind leg. Sif tends to jump away from you. Expect much of the fight to be chasing it.

Defeat Sif and be rewarded with the Covenant of Artorias.

New Londo Ruins

59. New Londo Ruins flooded: Key to the Seal, Transient Curse x 6, Rare Ring of Sacrifice

Start from Firelink Shrine and visit the Undead Female Merchant to purchase all Transient Curses from her. Head down to New Londo Ruins. Your objective is to rendezvous with Ingward, who would gift you the Key to the Seal. You require this item to open the flood gates of New Londo Ruins and unlock the lower portion of the area. Use a Transient Curse to allow you to fight the ghosts scattered throughout New Londo Ruins. The ghosts drop Transient Curse. Farm the ghosts if you need more Transient Curses, but farming is not necessary because you can purchase the item from Ingward. On your way to Ingward, you should be able to collect Transient Curse x 6 and a Rare Ring of Sacrifice. Ingward stands on the roof of a building. Reach him by climbing an iron ladder and exhaust his dialogue to receive the Key to the Seal. Use the key to unlock the gate to a lever and turn the lever to release the flood gates, hence unlocking the lower portion of New Londo Ruins. Here are some useful items to collect along the way:

• Large Soul of a Nameless Soldier x 2
• Soul of a Proud Knight
• Cursebite Ring
• Green Titanite Shard
• Humanity

60. New Londo Ruins unflooded: Very Large Ember & Titanite Chunk x 2, Dark Souls: Remastered

The unflooded lower portion of New Londo Ruins has Titanite Chunk x 2 and the Very Large Ember. The area provides the best source of Titanite Chunks, i.e. the Darkwraiths. Other useful items to collect include:

• Large Soul of a Proud Knight x 3
• Humanity
• Soul of a Brave Warrior

Grab the Very Large Ember and hand it over to Andre. You should have enough Titanite Chunks to upgrade the Reinforced Club to at least +12. Farm the Darkwraiths for Titanite Chunks to upgrade the weapon to +14. If you are lucky a Darkwraith might drop a Titanite Slab to allow you to upgrade the weapon to +15.

Four Kings

61. SL1 Four Kings, Dark Souls: Remastered

This gank boss is weak against lightning. Equip the Lightning Reinforced Club+5. Equip the Covenant of Artorias so your character would not fall through the arena and die. Stay close to a king, roll through a horizontal swipe (or a thrust or overhead attack) to position your character behind the enemy, and get in an R1. This fight has a time limit. The longer you drag out the fight, the more enemies would spawn. Kill one enemy at a time and as fast as you can. As an enemy performs its death animation, hit the dying enemy a few times to lower the shared HP bar of the boss. When you see a purplish-blue aura around an enemy, run or roll away because the enemy is charging up its AOE. When you see an enemy raise up an arm to charge a purplish-blue disk, raise up your Grass Crest Shield to block an incoming magic projectile.
