Ritual Material

In-Game Description

    Special material used in a Holy Chalice rite.

    Special body parts collected by the Healing Church.
    What was this gruesome bait used to lure?

    The additional rite Rotted Offering beckons ungodly forces,
    normally terrifying things, but also worthy prey for a special
    hunt.
Note: The same in-game description in US & UK versions. ✓

Overview

  • Conducting a ritual to create a Chalice Dungeon is fairly straightforward; when you've got a Chalice and the required ritual materials, approach a Chalice altar and select the Chalice Ritual option. In the Chalice Ritual menu you'll see the list of all your collected chalices in the large window on the left of your screen. Along the top of this window are four tabs, one for each class of Chalice, which affects the area that labyrinth will be set in. The central window shows the details of the ritual, including the Depth of the created dungeon, which is essentially the difficulty level, with 1 being the lowest and 5 being the maximum.

    The depth affects the required level for certain Basic and Rite Materials. For example, Depth 2 labyrinths will require Ritual Blood (2) and Tomb Mold (2), which can be acquired from the corresponding depth labyrinths or from certain chests and enemies from the previous Depth. The cost in Blood Echoes is also shown, along with the required materials, both for the ritual and any possible Additional Rites. If you have all of the required materials and are certain you want to use them, select the Conduct Ritual option to create the dungeon.
  • Basic and Rite crafting materials can be found mainly in the Chalice Labyrinths from loot chests or enemy drops, with the rarer ones required to craft specific labyrinths also found in the main quest. Progressing though the game, acquiring Hunter Badges, defeating bosses and clearing labyrinths will also unlock certain Basic Materials in both Bath Messenger Blood Echoes and Insight shops in the Hunter's Dream. Ritual Blood and Tomb Mold basic materials have a numerical value in brackets next to them. These correspond to the depth/difficulty of a labyrinth, and can also be found on the same depth or one depth below. The highest level of both of these items (5), can be purchased from the Bath Messengers since Patch v1.07 (available on NG+).
  • When using a Root Chalice to create randomly generated dungeons you'll usually have the possibility to conduct Additional Rites, at the cost of more materials. These rites add effects that can drastically change the conditions within each dungeon, usually making them much more challenging. They do carry some reward, however, usually in the form of increased item drops and Blood Echoes. There are four possible Additional Rites: Fetid Offering, Rotted Offering, Curse & Sinister Bell.

Effects

  • Yellow Backbone is used to create additional rite "Rotted offering" for depth 5 root chalice dungeons. This rite triggers one of, or a combination of, the following difficulty-increasing effects: The Eye Collector appears and summons Mad Ones. Tomb Prospector Hunters often appear as enemies. The Labyrinth Ritekeeper appears. It will patrol large rooms, gather other enemies around it and then strengthen them. Even when the Ritekeeper is killed, the enemies will retain their powered-up status. It also increases the chance of getting very powerful Blood Gem effects, but this comes at the cost of strong negative effects.

Yellow Backbone: 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.
