The Black Gulch
Head into the Black Gulch and enter the cave to the left. Light the bonfire and prepare yourself: there are many poisonous enemies ahead.
Leave the bonfire cave and head to the left. There are plenty of poison statues and black holes ahead. Destroy the statues as you come across them to prevent their poison spit from affecting you. Be careful, though, as some of them will still attempt to poison you as you destroy them. You can use Common Fruit to slow the effect of poison, and Poison Moss to heal it.
When you reach the first set of black holes, carefully approach them. If you have Firebombs, toss them into the middle and right holes. This ignites the holes and damages the enemies hiding within. Both enemies will come after you, so be ready to fight if the Firebombs don't kill them.
Head to the left of the first three black holes to find a cave. Take out the poison statue near the entrance, then open the coffer at the end to obtain a Shotel and a Great Magic Weapon. Coming out of the cave, only the first black hole to the left has an enemy hiding inside, so deal with it accordingly. Be careful moving forward because there are several poison statues along the upper ridge to the left that are difficult to destroy without proper ranged weaponry, however.
The cave to the left, just beyond the overhead statues, contains a worm-like monster different from what's normally found in the black holes. If you approach it, it lunges out of the cave. Back away slightly, just out of its attack range. It will attempt to attack and miss. As soon as it misses, move in to quickly strike, then dart back outside of its attack range. Repeat this process until you get the best of it.
Destroy the pottery next to the cave to find the Soul of a Nameless Solider, Scraps of Life, and a Torch. Another worm creature attacks from the hole ahead on the left wall, so deal with it the same way as before. After that, the next black hole on the ground is empty, but there are three holes behind it. The two holes on the right house creatures. Firebomb both, or get close, then back away to lure it out if you don't have any Firebombs. Another creature awaits in the middle hole in the next row.
The pottery here contains a Radiant Lifegem. Pick up the item, defeat the creatures, then head into the cave to the left. Destroy the statues, including the statue behind the chest at the end, then open the chest to find a Divine Blessing. Head back out of the cave to find another creature in the black hole across the room. This is the last creature in the room. Ahead is the mist entrance to the boss battle against the Rotten.
Boss Battle: The Rotten
The battle against the Rotten is more about the environment than the enemy. Beware the fire pits scattered throughout the battleground: if you touch any of them, you'll take considerable damage. If you continue to linger in the pits, you will certainly die a horrible, fiery death.
Most of the battle is spent locked on to the Rotten, which means you may have difficulty determining when a fire pit is behind you. To avoid backing into a fire pit, circle strafe around the fire pit in the center of the battleground. If you stay close to the center pit, you'll have plenty of room to avoid the others.
The Rotten only uses a handful of attacks. If you have a shield that absorbs 100 per cent damage, this is a much easier fight. However, even if this is the case, many of the Rotten's attacks drain your stamina bar completely, or at least very close to it. Your best course of action is to dodge the attacks with specific timing so you don't take any damage, then strike once or twice depending on the speed of your weapon. If you wish to take a more careful approach, only dodge the linear attacks and block the horizontal sweeping attacks. It's much easier to dodge the linear attacks, but you'll have fewer opportunities to counter attack, which will draw out the fight.
When the Rotten is close to you, it uses a single, horizontal sweeping attack that drains your stamina bar almost completely if it's blocked, so dodge it if at all possible. It also uses a single, linear chop, and three chops in rapid succession. The single chop is easily dodged to the left or right, while it's best to block the first two chops, then dodge the third one. You can actually dodge all three, but the timing is pretty strict.
If you back away from the Rotten, it uses a variation of the single, linear chop, but it has deceptive range. Also be ready to block or dodge when you see the Rotten pull its weapon back over its head. It's very difficult to get far enough away to avoid this attack completely. In almost all cases you must either block the attack or dodge it. If you block, it drains your stamina bar almost entirely. If you see the Rotten begin to regurgitate, back away to avoid two dark spits that happen back to back. As soon as the spits conclude, rush back in to counter attack.
Once the Rotten reaches approximately 50 per cent health, it adds two attacks to its arsenal. The first is a variation of the long-range chop. This time a dark fog emits from its weapon and extends outward rapidly. This is a linear attack, but it's difficult to dodge without precise timing. You must dodge to the left or right. If you dodge back, it will still hit. However, if you hug the Rotten, the attack misses completely. This can be risky if your timing is off though.
The other new attack the Rotten uses is a burst of dark mist that emits from its body. This happens when the Rotten makes a motion similar to the regurgitation animation. Simply back away from the Rotten to avoid this attack, since it doesn't have much range.
With the Rotten down, quickly move through the fire on the side of the arena where an item can be seen. Pick up the item to find a Fire Seed. This concludes your time in the Black Gulch.
