Candle Wolf Black Metal

Candle Wolf Black Metal is a Tier-3 Faction Metal for developing and upgrading weapons and armor at Chokufunsha.

Locations
Candle Wolf Black Metals may drop from GOTO-9 on 23F ECHIZEN-JIMA. The boss room will always be right next to the elevator, so farming this metal is fairly simple. His only other drops are Candle Wolf equipment or Kill Coins.

Faction Metals may appear in Trap Room chests on certain floors. A Trap Room is a room containing a single Golden Chest, which, when opened, will seal the entrance to the room and spawn enemies that must be killed before the room can be unlocked again. The chest will always contain either a Faction Metal of that Area's tier or one tier below, or Kill Coins. The first four color tiers are Blue, Green, Black and Red. For example, Max's Area (1-10F) is a Tier 1 Area, so Trap Rooms there will only drop Blue Metals. However, Jackson's Area (11F-20F) is a Tier 2 Area, so Trap Rooms there may drop Green or Blue Metals. Certain Faction Metals can only naturally be found this way, as there is no Mid-Boss for certain Factions in some Areas. COEN on 3F TAMATA (Max's Area) can drop D.O.D. ARMS Blue Metals, but you cannot farm D.O.D. ARMS Green Metals in this way, as there is no COEN in Jackson's Area. Certain Trap Rooms may not always appear, based on tower rotation. See this spreadsheet.

Following an update,  Haters  may now drop Golden Chests which have drops like a Trap Room within that Area, making them a new source of Faction Metals.

May also be obtained at Gyaku-Funsha shops, as a reward from Lost Bags, appear in the daily Hernia lineup, purchased for R-Points, or from Uncle Prime. Some Quests will reward this metal.
