Description Giant rats inhabiting the central sewers of Yharnam in large colonies. While not too dangerous on their own, they are never encountered alone and can become a serious problem in groups if you don't have a few Molotovs handy. Labyrinth Rats use basic claw swipes, forward lunges and a bite combo; their attacks have enough windup for you to quickstep out of the way and counterattack, but it's still a good idea not to let them get too close. They're not quite as agile as Rabid Dogs, but they move quickly and will keep up the pressure by constantly running toward you if you try to back off. They will also sometimes leap sideways immediately after striking in an attempt to avoid your counterattack. Although Labyrinth Rats cannot be staggered or interrupted, you can knock them out of their attacks by shooting them. Strategy In many spots where groups of Labyrinth Rats are visible below you, you can hit several at once with a single Molotov from a safe vantage point - just be careful not to stand too close to the edge, or risk falling into the lower area and being swarmed. If you have no choice but to face them on even ground, try to avoid being seen by several at once - fighting a group leaves very few safe openings for you to attack, though thrust attacks from weapons like the Saw Spear in transformed mode will stop them in their tracks at a safe distance. If you do end up fighting several at once, back away from them and wait for a chance to use a sweeping horizontal attack to hit all of them at the same time - if you can keep up the combo long enough to kill one or two of them, you can buy yourself enough breathing room to mop up any that remain. Variants Basic variant found throughout Yharnam. Variant with eyes glow, found in Recovery Room before Research Hall. Variant with pustules, found in various Chalice Dungeons. Inflicts rapid poisoning. Notes Preset Chalice Dungeons: Pthumerian Labyrinth, Central Pthumerian Labyrinth, Hintertomb, Lower Hintertomb, Lower Pthumerian Labyrinth, Cursed Pthumerian Defilement, Ailing Loran, Lower Loran, Isz Gravestone, Pthumeru Ihyll In Chalice Dungeons variants with purple aura have different drop pool and rates from regular version. Also variant with Rapid Poison status has the same stat (HP, Echoes, Defences, Multipliers & Bonuses) and drop (pool & rates).

Ritual Materials: Drop Pools

For the most part, items dropped by enemies are decided simply by a random per cent chance from that enemy's own list of potential items. When an enemy appears in a dungeon, it sometimes has one or more of its drops determined by the dungeon's Depth, in order to give better rewards for more challenging dungeons. Such items are selected from a pool of similar items, and these pools are shown here. The upshot of this is that an enemy might drop a Tomb Mold (1) in the Depth 1 Pthumerian Root Labyrinth, but would drop a Tomb Mold (5) instead in a Depth 5 Isz Gravestone dungeon.

Pool Name	Depth 1		Depth 2		Depth 3		Depth 4		Depth 5
Tomb Mold Pool		Tomb Mold (1) Depth 1		Tomb Mold (2) Depth 2		Tomb Mold (3) Depth 3		Tomb Mold (4) Depth 4		Tomb Mold (5) Depth 5

Base Level: Blood Echoes, HP, Damage and Def. Multipliers

For enemies that also appear (or exclusively appear) in dungeons, their stats will be shown at the base level, because their exact stats at any given point are calculated from these base values. The basic formula is: Total Value = Base x A x B x C x D. Multipliers written down below were datamined directly from the game files. Multiplier A represents depth (1 - 5) of the chalice dungeon; multiplier B is layer (1 - 4) of the specific chalice dungeon; multiplier C is used when dungeon is Pthumeru Ihyll; multiplier D is for calculating blood echoes when additional curse rite is used.
