R&D Materials

From Let It Die Wiki
Jump to: navigation, search

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 has settled in.

Material Types and Locating[edit | edit source]

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

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

Tier Floors Iron Aluminum Copper Wood Oil Cloth**
1 1 - 10 Iron Scraps Aluminum Scraps Clump of Copper Scraps Veneer Plank Waste Oil Cotton
2 11-20 Wire Mountain Aluminum Can Piece of Broken Copperware MDF Vegetable Oil Hemp
3 21-30 Mass of Iron Bolts Aluminum Engine Part Copper Wire Mountain Rosewood Crude Oil Leather
4 31-40 Steel Pure Aluminum Pure Copper Walnut Mineral Oil Wool
5 31-40 Ultra-Pure Iron Aluminum Alloy 7075 Oxygen-free Copper Mahogany Chemo-Synthesized Oil Silk
6 41+ Special Steel Aluminum Alloy 9048 Beryllium Copper Snake Wood Biofuel Carbon Fiber
7 51+ Chrome-Moly Aluminum Alloy 9050 Corinthian Bronze Black Coal Tiger Grease Aramid Fiber
8 51+ (Cont.) Tamahagane Aluminum Alloy 9051 Orichalcum Lignum Vitae Fatback Polyarylate Fiber

Material Specific floors[edit | edit source]

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). Material-specific floors are the only way to obtain Tier 5 versions of Iron, Aluminum, Copper, Wood, and Oil.

**Any type of cloth can be found on any Cloth-only floor. These include Cotton, Hemp, Wool, Leather, and Silk. However, Carbon Fiber can only be found in floors 41 and above

Tuber and Faction Metals[edit | edit source]

Tuber Metals[edit | edit source]

Tuber Metals are one of the two types of Rare Metals. They are rarely dropped by correspondingly named Tubers

Tuber Metals
Scratch Metal
Bullet Metal
Bone Metal
Hovering Metal
Reversal Metal

Tuber Metals can also be obtained through certain Quests.

Faction Metals[edit | edit source]

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 and Don corresponds to a faction, and each set of 10 floors corresponds to a color:

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


D.O.D. ARMS White steel
War Ensemble Red Napalm
Candle Wolf Black Thunder
M.I.L.K. Pale Wind
Floor Color D.O.D ARMS War Ensemble Candle Wolf M.I.L.K
1-10 Blue D.O.D. ARMS Blue Metal War Ensemble Blue Metal Candle Wolf Blue Metal M.I.L.K. Blue Metal
11-20 Green D.O.D. ARMS Green Metal War Ensemble Green Metal Candle Wolf Green Metal M.I.L.K. Green Metal
21-30 Black D.O.D. ARMS Black Metal War Ensemble Black Metal Candle Wolf Black Metal M.I.L.K. Black Metal
31-40 Red D.O.D. ARMS Red Metal War Ensemble Red Metal Candle Wolf Red Metal M.I.L.K. Red Metal
41-50 Purple D.O.D. ARMS Purple Metal War Ensemble Purple Metal Candle Wolf Purple Metal M.I.L.K. Purple Metal
51+ Orange D.O.D. ARMS Orange Metal War Ensemble Orange Metal Candle Wolf Orange Metal M.I.L.K. Orange Metal
51+ (Cont.) Platinum D.O.D. ARMS Platinum Metal War Ensemble Platinum Metal Candle Wolf Platinum Metal M.I.L.K. Platinum Metal
Forcemen 44CE D.O.D. ARMS 44CE Rare Metal War Ensemble 44CE Rare Metal Candle Wolf 44CE Rare Metal M.I.L.K. 44CE Rare Metal

This means that, 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.

Note[edit | edit source]

There are Chests which can provide Blueprints and Materials.
