Wandering (or roaming) bosses can be rarely found in Depth 4 and 5 dungeons. They are mob versions of bosses with less HP that act like strong enemies on your way through the layer. The main defining feature of true wandering bosses is that they don’t respawn once killed, and they always drop a gem. There are only 5 true wandering bosses: Abhorrent Beast, Blood-starved Beast, Pthumerian Descendant, Pthumerian Elder, Watchdog of the Old Lords Wandering bosses can be most frequently found on Layer 2 - 4, but in very rare cases on Layer 1 as well. The only wandering bosses that can be encountered on Layer 1 are Abhorrent Beast and Pthumerian Elder. Rarity of wandering bosses ► Pthumerian Descendant is the most common wandering boss. Occasionally, you can even encounter a double Descendant spawn in garden area, or find multiple wandering Descendants in different parts of the dungeon layer. It’s the only wandering boss that can be encountered in Sinister Isz. Areas: Pthumerian Defilement, Pthumeru Ihyll, Sinister Pthumeru Ihyll, Sinister Isz Count: 24 ► Pthumerian Elder is a close second. In rare cases you can find wandering Pthumerian Elder and Pthumerian Descendant on the same dungeon layer. Areas: Pthumerian Defilement, Pthumeru Ihyll, Sinister Pthumeru Ihyll Count: 18

► Abhorrent Beast is the most common wandering boss in Loran dungeons, with one unique instance in Sinister Ihyll. Areas: Ailing Loran, Lower Ailing Loran, Sinister Lower Loran, Sinister Pthumeru Ihyll Count: 12 ► Blood-starved Beast is a surprisingly rare wandering boss found exclusively in Loran swamps. Areas: Ailing Loran, Lower Ailing Loran Count: 3 ► Watchdog of the Old Lords while equally rare as wandering Blood-starved Beast, is much more significant encounter due to him being exclusive to Pthumeru Ihyll, and most of them being on Layer 4. Since there’s only 20% chance Layer 4 will be opened for the player when creating the chalice, it lowers the chance players will discover this wandering boss. Areas: Pthumeru Ihyll Count: 3

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.
