Invention training

There are many ways to gain experience for the Invention skill. The first thing to do is start the tutorial by speaking to Doc.

Inspiration
The first thing necessary for Invention is Inspiration, which is gained by levelling Invention or from training other skills. Inspiration is used to discover new items. There is an Inspiration cap for each level beyond which no more inspiration is earned.

Discovering and Manufacturing
Before inventing, you need to discover and manufacture. At level 2 Invention, this is the Augmentor, and at level 4 it's the Divine charge. Discovering requires Inspiration.

Interface when discovering new invention:

Continue building prototypes until the correct 5 components are chosen:

Rearrange the ordering of the components to reduce the amount of inspiration needed:

Poor<Satisfactory<Good<Excellent<Perfect

To discover an item, keep using modules in the boxes until you get the correct 5. Then sort them in the correct order and try use the least amount of inspiration. 'Perfect' is the best option to get.

To manufacture an item, you will need components which are obtained from disassembling items.

Disassembling items
Most alchable items can be disassembled for components. The components given can be checked by using Analyse on the item. The lower tier-ed the item, the higher chance you'll get junk (for example, it is more likely to receive junk by disassembling an adamant platebody than a rune platebody).

Components are used to manufacture items you have discovered. They are also used in gizmos.

Components
There are a wide variety of components that can be obtained from multiple items. Specific items can give specific components, such as a cabbage giving Brassican components. Components are used to manufacture items and can optionally be used in creating perks with a gizmo.

Augmenting weapons
To augment a weapon, players will need an Augmentor. This can be manufactured with divine energy (the amount depends on the tier: 2,000 pale energy or 225 incandescent energy). The augmentor can then be used on any augmentable weapon to make that weapon untradable. The weapon can now be levelled up and gizmos with perks can be added to it.

Perks
Up to 5 types of components can be exchanged for a perk (you can use the same component 5 times if you wish). The perk received is often random, depending on the component, with junk components giving almost-useless perks. A list of what perks gained can be seen when adding components to your gizmo shell. When creating the gizmo, one of those will be selected. Perks can have certain tiers ranging from 1-4.

Gizmos
Gizmos can only be added to augmented weapons. A weapon gizmo shell can be manufactured with 10 blade parts, 5 crafted parts, and 2 strong components. They can then be charged with other components (obtained from disassembling) to create perks.

Creating gizmos gives a good chunk of experience.

Disassembling augmented weapons
Finally, you can disassemble an augmented weapon for components.
