This article or section is incomplete and could do with improvement. Reason: Still working on how perk weight works You can discuss this issue on the talk page or edit this page to improve it.

Perks are effects added to weapons, armour, or tools with Invention. They are created by combining materials inside a gizmo shell. The resulting gizmo is attached to an item that has been augmented with an augmentor.

Perks are created within three types of gizmo shells (weapon, armour and tool). Perks can be specific to a gizmo shell type or can be used in two or more gizmo shell types. For example, the Mobile perk is only used in a weapon or armour gizmo shell and not in a tool gizmo shell.

Certain perks such as Efficient (a perk used to affect the drain rates of augmented armour, weapon, or tool items) are used in all gizmo shell types. Each item worn with an Efficient perk is affected individually. Most perks provide a general effect instead of affecting a specific item. These perks do not stack with themselves, and the gizmo with the highest rank will take priority. For example, if a player is wearing an augmented top with Crackling 3 and an augmented bottom with Crackling 2, they will only receive the benefits of Crackling 3.

Creating perks

Adding materials to a gizmo

Creating a perk successfully

Perks are created in gizmo shells using materials from the Bag of materials. Gizmos can hold up to 5 slots of items. Common materials require 5 materials to occupy a slot. All other materials (including junk) take 1 material to occupy a slot.

Each material has a set of perks it can give along with a weighting for each perk. For example, the following table describes the available ranks of Lucky when using Silent components or Fortunate components:

Silent			Fortunate			Mixed
Materials	Rank		Materials	Rank		Materials		Rank
						Silent	Fortunate
1	1		1	1		1	4	2–5
2	2		2	1–2		2	3	2–5
3	3		3	1–3		3	2	3–5
4	4–5		4	1–5		4	1	4–5
5	5		5	1–5

Different perk weights from different materials stack as well. For example, combining 3 Silent components with 1 or 2 Fortunate components gives the possibilities of 3–5 for Lucky. From this example it's evident that a component's perk weighting affects both the minimum and maximum rank, and that the sum total does as well.

It is possible for perk production to fail; this is also dependent on perk weighting. Having more components lowers the chance of failure, with having 2 or 3 component slots generally guaranteeing success. Some materials, however, cannot ever guarantee success by themselves; e.g. 5 Fungal components can still fail. When perk creation fails, no materials are lost nor is the gizmo. After either success or failure, the same materials can be attempted again (assuming enough are owned) or the process can be started from scratch.

When trying to obtain a particular perk, it can improve one's chances to use different materials that all give the same perk. For example, 3 Imbued components plus 2 Magic parts gives a better chance of the Crackling perk than 5 Imbued components, which can be seen in the list of possible perks.

A higher invention level improves the chance of making better non-guaranteed perks such as Precise 4, Equilibrium 2. However this effect does not apply to guaranteed perks such as Precise 5.
