For example, if the HP multiplier is "x2", the NPC will have twice the health that the player would have if they had identical stats and equipment. The NPC's attack multipliers are applied before the damage is affected by the player's defenses and resistances. Damage received by the NPC is slightly more complicated. When the player does damage to the NPC, the raw damage is put into a formula and computed against the NPC's resistances. These resistances are multiplied by the values in the '''''Physical/Magic/Fire Defense''''' columns before calculation. Afterward, the remaining damage is reduced by resistances, it is then multiplied by the Damage reduction multipliers in the '''''Physical/Magic/Fire Reduction''''' columns. The output damage remaining is the dealt to the NPC.{| class="wikitable" style="text-align: center"|-!rowspan="2"| Enemy !!rowspan="2"|HP !! rowspan="2"|Stamina<br/>Damage !! colspan="3"| Attack !! colspan="3"|Damage Reduction !! colspan="3"|Defense !! colspan="3"| Resistance|-!Physical!!Magic!!Fire!!Physical!!Magic!!Fire!!Physical!!Magic!!Fire!!Poison!!Plague!!Bleed|-|style="text-align: left" |[[Depraved One]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || Immune || - || -|-|style="text-align: left" |[[Giant Depraved One]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || Immune || - || -|-|style="text-align: left" |[[Giant Depraved One]] (Black Phantom) || 3.7 || x1.44 || x2.775 || x2.775 || x2.775 || - || - || - || x2.1 || x2.1 || x2.1 || Immune || - || -|-|style="text-align: left" |[[Phosphorescent Slug]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || Immune || Immune || -|-|style="text-align: left" |[[Poison Jelly]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || Immune || Immune || -|-|style="text-align: left" |[[Giant Mosquito]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || Immune || Immune || -|-|style="text-align: left" |[[Crystal Lizard]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || Immune || Immune || Immune|-|style="text-align: left" |[[Dirty Colossus]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || Immune || Immune || Immune|-|style="text-align: left" |[[Primeval Demon]] || x1.85 || x1.44 || x1.85 || x1.85 || x1.85 || - || - || - || x1.4 || x1.4 || x1.4 || - || - || -

:*Note: The [[Primeval Demon]] shows up one [[World Tendency]] lighter than Pure Black and is likely to drop a [[Colorless Demon's Soul]] when killed.
==Walkthroughand Map==;[[https://web.archive.org/web/20190331003159/http://www.geocities.jp/kouryakubo/ds_en/chart/chart052.html 5-2 Leechmonger Archstone Map]] - numbered sections below correlate to circled numbers on the map
#Your starting point. Most of this level consists of a poison swamp, so bring along equipment that boosts poison resistance and HP regeneration. [[Royal Lotus]]es are also essential when you do get poisoned, as all Healing effects will be halved while you're poisoned. Another tip is to island hop, you only get poisoned when standing in the putrid liquid. So if you see any islands, head for them and use them as healing stations. Regular movement is reduced to a walk, sprints are reduced to a normal run and you cannot roll while in the swamp. All enemies in the level are weak to Fire-based attacks and are unaffected by the movement penalties of the swamp.
#The plank here can be knocked down from the opposite side of the gap for a much appreciated shortcut past most of this level.
#There is a large group of Poison Jellies around here. Killing them is recommended, as they do not respawn and will drop Lotus items.
#A [[Meat Cleaver Black Phantom]] patrols these islands. Capable of rolling in the Swamp.Can be seen on approach in silhouette and by vapour caused by footsteps. [[ Cat's Ring]] and Pure [[Suckerstone]] on islands.
#[[Giant Depraved One]]. Lure the 3 regular [[Depraved OnesOne]] s out with ranged attacks, then rush the island and fight the Giant by outflanking his sides. Alternatively, equip a [[Thief's Ring]] and sneak behind them all, by hugging either wall beside the island.
#You're out of the Swamp for now, so use a [[ Royal Lotus]] to heal up any poison. Also, be ready for the ambush by the [[Giant Mosquito]]es as you pass this point. If you have [[ Fire Spray]] , their weakness to fire will let you kill each quickly for 2-4 MP each. Many players choose to jump off the elevated walkway at the start, and rather walk underneath it, since falling off it could be a bigger risk than another minute in the swamp.
#The alcove in the wall to the left of here has 5 [[Depraved OnesOne]] s in it, who wish to ambush you. If you walk by with the [[Thief's Ring]] equipped they likely won't notice you. Otherwise be prepared. As you drop back down to ground level, feel free to explore the marsh to the left of this position for another [[Thief's Ring]] and a [[Dark Moon Grass]] (full HP and heals status ailments).
#Before you get to this point you might notice all of the slugs hanging out to your left. Note this spot, as the Large Sword of Moonlight will appear here once you knock down their nest. There is a Chunk of [[Suckerstone]] along the far wall if you want it now, but you might want to knock down the slugs on one of the side walls and kill them now so you have an escape path. That done, this Point has two [[Giant Depraved One]]s , and a Shaman. Lure them out one by one with arrows and fight them on the small bit of open ground here. Or use the [[Thief's Ring]] to run away and hit them in the back or use a bow and lots of patience. And don't forget to keep your eye out for [[Giant Mosquito]]es! It's also possible to keep to the right wall of the outside of the village and slowly creepy up to the fog gate, only grabbing the attention of the Shaman. All while wearing the [[Thief's Ring]] of course.
#This lone leech is holding the [[ Dull Gold Armor]] , the same as Selen's, for female characters. Make sure you have some inventory weight available before killing it.
#You can climb the wooden walkway from here towards the Slug Nest. Note the purple spot to the right, this is where the [[Primeval Demon]] appears at Pure Black [[World Tendency]]. As you climb, you will encounter multiple slugs who will attempt to knock you off the walkway.
#Attack the Slug Nest here several times until the whole thing falls to the ground below. It is safer to melee attack the nest from the left hand side (as you approach it ) as there is a barrier to impede your fall. As you follow the path to drop back down safely, grab the Soul in front of you, and the one behind you when you make the first small drop.
#The [[Filthy Woman]] merchant appears just inside the shanty town. She now sells [[Mirdan Scale Mail]] (30,000 souls for the whole set). She also sells a couple of [[Dark Moon Grass]] for 10,000 each! Also, there is a lot of twists and turns to this area, many concealing [[Depraved OnesOne]] s of various types. You can pick up 4 [[Dark Moon Grass]]es under the central raised structure. Explore this whole area very thoroughly.
#This small pathway will lead you to the shortcut at Point 18, letting you skip the Poison Swamp completely. You will also find a [[Crystal Lizard]] along the way, and be able to snipe those 4 [[Giant Depraved One]]s at Point 11.
#The Shaman below you drops the [[ Shaman's Clothes]] set. Be sure to have inventory weight available before killing him.
