As of Patch This information is reliable as of patch 2.0.201.64.

Bits are components used for Tinkering. Bits can be denoted by either colored dots or by letters and numbers. On the wiki, letters and numbers will be used. 0 bits on game start will be a random choice between <A>, <B>, <C>, and <D> bits. The wiki uses <0> for ease of use. Also, during world generation, there is small chance for each of tinkering recipes to replace one or more of their advanced bits with two bits of previous tiers. These "altered" recipes remain the same for the entire game.

Bits can be acquired by disassembling an item that is able to be disassembled using the relevant skill; the most obvious such source is Scrap, which is useless on their own. Alphabet bits are very common and are used for base material, while numbered bits are rare - generally, the higher the number, the rarer.

General Sources

  • Scrap can be found lying around on the ground, by scavenging, or in the inventory of legendary Barathrumites or tinkers
  • Inside various containers or looted from killed creatures.
  • Destroyed & Dismembered mechanical creatures, such as turrets and robots, might also leave some random scrap behind, in the same manner as other creatures leave corpses.
  • Traders dealing with technical items, such as Argyve in Joppa, usually have a selection of scrap for sale, as well.
  • Most bits are obtained by disassembling pieces of scrap or various technological artifacts
    • Note that when disassembling something, you are guaranteed to always receive its most valuable bit(the rightmost one); you then have a 50% chance of getting each remaining bit; the percentage chance for additional bits can be improved with either a Basic toolkit or an Advanced toolkit (their bonuses do not stack).

Reliable Sources for Specific Bits

Because on occasion items will have their most valuable bit changes to two of a lower bit, another method of getting a bit can include disassembling that item that usually has a higher bit.

For a full query of every item of that bit, use the link in the table or visit /Items by bits.

Bits Sources Table Link
<A><B><C><D> These bits are from an source that gives <0>, but what kind will depend on the run. The most common source of these are scrap and mk I and mk II grenades. Most items contain a <0> bit at the very least, so there is usually a 50% chance of obtaining a <0> bit when disassembling something.

Can also be farmed by defusing and disassembling mines laid by  miner Mk I bots and its higher-level equivalents.

Another farming method is to kill  boosterbots, which drop a large number  empty injectors that will disassemble into two 0 bits.

/Items by bits#A, B, C, D
<1> Gained by deconstructing  fidget cells,  lead-acid cells, and regular  chem cells often dropped by defeated robots. One spot with low level robots that drop chem cells is upper and lower  Grit Gate- go there without a  droid scrambler to also gain experience. The stun rods that they will drop also disassemble into a <1> bit.

More advanced grenades also have <1> bits. If you're lucky, you can encounter a miner Mk I or above whose mines contain this bit.

/Items by bits#1
<2> Extracted from  muskets,  Issachar rifles, and similar guns. Issachar rifles are always carried by  goatfolk yurtwardens in the  jungles and  Issachari riflers in the  salt dunes. /Items by bits#2
<3> Extracted from recoilers,  pump shotguns and  semi-automatic pistols.  Mafeo will always sell Grit Gate recoilers that can be used as a source for this.

Semi-automatic pistols can be obtained in unlimited quantity by disarming the  microturrets created by  spring-turret grenades, effectively allowing the <2> bits used to make such grenades to be upgraded to <3> bits.

/Items by bits#3
<4> Extracted from high-level guns, such as a  carbine or a  chaingun, but these tend to be expensive.

One way to get them is to disarm  chaingun turrets (They will only drop them if disarmed, not if killed.)

/Items by bits#4
<5> Extracted from  sphynx salt injectors and  ubernostrum injectors, which are often sold by Mafeo and similar merchants. Weapons like  nullray pistols or  vibro blades that may be useless for the current character can also be disassembled.

Much rarer than <6> bits, contrary to its order.

/Items by bits#5
<6> Extracted from  Templar phylacteries and  nuclear cells. /Items by bits#6
<7> Can be reliably salvaged from  leering stalkers, specifically its head and weapon, if it can be killed.

One guaranteed <7> AI Microcontroller from the  small sphere of negative weight can be found in the  waterlogged tunnel under  Joppa. <7> bits can also be disassembled from several high tier ranged weapons.

/Items by bits#7
<8> Lower levels of caves often spawn  dynamic turret tinkers and  phase cannon tinkers, which place  phase cannon turrets that can be disarmed for the weapon, and often also spawn with  antimatter cells. /Items by bits#8
