Let It Die Wiki

R&D (Research and Development) Materials are items used to develop equipment from Blueprints.

Once a Blueprint has been brought to Choku-Funsha in the Waiting Room, the R&D menu will display the materials required to develop a piece of equipment. Handing over the Materials and SPLithium needed will make the equipment purchasable with Kill Coins, after a waiting period determined by the equipment's tier. Only Materials in your currently active Fighter's Death Bag and the Storage Chest are accessible by Choku-Funsha.

The Wandering Shop, Gyaku-Funsha, sells both common and rare crafting materials. The selection offered varies depending on which floor the shop appears.

Material Types and Locations[]

There are six types of common materials that can be found in a variety of forms throughout the tower: Aluminum, Copper, Iron, Oil, Wood, and Fiber.

In All-material type floors, any type of common material can be found, but only in one "quality tier" according to floor number:

*Any type of fiber (up to 5 Stars) can be found on any Fiber-only floor. These include Cotton, Hemp, Wool, Leather, and Silk.

Material Specific Floors[]

There are also material-specific areas. In these areas, the materials that appear have a chance to be up to two tiers lower or one tier higher than the current floor's tier.

An example of this is Takayama, an Aluminum-only area. Because it's on the 34th floor, normally only Pure Aluminum (Tier 4) would appear, but because this district is material specific, you can also find Aluminum Can (Tier 2), Aluminum Engine Part (Tier 3), and Aluminum Alloy 7075 (Tier 5).

Tuber and Faction Metals[]

Tuber Metals[]

Tuber Metals are one of the two types of Rare Metals. They are rarely dropped by the corresponding Tubers, and can also be obtained through certain Quests.

Faction Metals[]

Faction Metals are the other Rare Metal type, primarily obtained as drops from Mid-Bosses and Dons, and from the gold chests in Trap Rooms.

They can also be obtained through certain Quests, purchased at Gyakufunsha, or rarely found in Uncle Prime boxes or login rewards.

Each Mid-Boss, Don, and Forcemen corresponds to a faction, and each set of 10 floors corresponds to a color:

Tower of Barbs' Factions
Faction Mid-boss Don Forcemen
D.O.D. ARMS COEN Max Sharp White Steel
War Ensemble JIN-DIE Colonel Jackson Red Napalm
Candle Wolf GOTO-9 Crowley Black Thunder
M.I.L.K. U-10 Taro Gunkanyama Pale Wind

For example, the JIN-DIE on 16F Kaga drops War Ensemble Green Metal, while the GOTO-9 on 11F Maka-Tsutsumi drops Candle Wolf Green Metal. Trap Room chests follow the color rules but can always drop metals of any faction.

Certain metals can't be obtained by boss drop because they correspond to boss combinations that don't exist, which means Trap Rooms are the main method of obtaining them. These metals are D.O.D. ARMS Green Metal, Candle Wolf Blue Metal, M.I.L.K. Blue Metal, M.I.L.K Green Metal, and M.I.L.K Black Metal.

Forcemen metals can only be obtained from defeating related Forcemen on Hard or Nightmare modes.
