Rom, the Vacuous Spider — Bloodborne
Rom, the Vacuous Spider — Bosses, Bloodborne. Moonside Lake · Lower Pthumeru · Root Chalices

Location and loot
| Location | Condition |
|---|---|
| Old Hunter Henryk Confederate : On the second floor, between two couches near the treasure chest. | He will not appear unless you have defeated him at the Tomb of Oedon ( also Eileen has to survive the fight as part of her quest line ) and are wearing the " Impurity " rune. |
| Younger Madaras Twin : Right next to the Byrgenwerth lamp. Walk off the little ledge, and it’ll be on that plateu with you, nestled between two trees. | You cannot summon him if you have already killed him outside the Small Windmill or are not wearing the " Impurity " rune. |
| Mensis Scholar Damian : In plain view outside the boss room. | Bear in mind that summoning him will prevent you from being able to summon Henryk or the Younger Madaras Twin in Byrgenwerth , but his habit of spamming the Choir Bell makes him well worth the tradeoff. |
With patch v1.07 you are able to summon NPCs to come to your aid, just like cooperative play, including inside Chalice Dungeons. To do so, first you will need to acquire the “ Old Hunter Bell ” from the messengers in the Hunter’s Dream. In some areas you may be able to summon up to two NPC Hunters.

Strike the flanks
Rom and her small spiders strongly resist hits to the head. Circle around to strike the side or back; Bolt is useful.
Clear the first wave
At first, Rom does not attack: eliminate the small spiders while avoiding multiple engagements. Replenish stamina before a series of hits on Rom.
- Chalices do not follow the NG cycle. Root base values must be multiplied according to depth, layer and rites; they do not describe a specific fight.
- Solo HP and echoes without runes. The displayed defenses are for NG; their NG+ scaling is not quantified here.
- A defense is a calculation value, not a damage reduction percentage. A Poison resistance of 999 does not imply immunity.
