The Invention master cape is the cape awarded for achieving True skill mastery by reaching level 120 Invention. Its appearance is different from regular skillcapes, and has a separate, unique emote from their level 99 skillcape counterpart. The cape is sold by Doc for 120,000 coins.

It can be stored in a cape rack of a player-owned house.

Perk

The Invention master cape inherits the perk of the base cape: it provides a 2% charge drain reduction, which stacks multiplicatively with other reductions.

The Invention master cape gains a new perk that increases the chance of receiving uncommon and rare components when disassembling by 20%.

Up to three perks of the capes of accomplishment can be added to the max cape, the completionist cape, and the trimmed completionist cape and up to two perks of the capes of accomplishment of a specific skill type can be added to the respective expert cape of accomplishment. This can be done by using a cape of accomplishment with the desired perk on one of the capes. The cape of accomplishment is then lost in the process. To make space for other perks, it is possible to later remove the added perks, but with no reimbursement. All of the added perks are shared among max cape, completionist cape, and trimmed completionist cape, thus it is not possible to have different configurations of perks on the different capes.

Details

Charge drain

The charge drain reduction is simply a 0.98 multiplier on top of any and all other reductions currently in effect - see charge pack for more details.

Disassembly chances

This section or article is incomplete and could do with improvement. Reason: need a large amount of disassembly data to fully confirm this - it may adjust weights without scaling back the total weight - see Disassemble#Invention master cape You can discuss this issue on the talk page or edit this page to improve it.

The disassembly chance increase applies to rare and uncommon materials, at the expense of the chance of getting common materials. The after-junk chance of getting a rare/uncommon material is increased by 20%, and the increase is removed proportionally from the common materials. The cape does not change junk chance. This is better understood with some worked examples, as well as understanding how materials are rolled when disassembling (see Disassemble#Material distribution).

The chance increase only applies when disassembling items by hand with the Disassemble action or the Breakdown perk - the mk. I and mk. II machines do not benefit from this.

Example 1 - logs

The basic disassembly information for logs is:

• Simple parts - 99%
• Living components - 1%
• 1 material per log
• Junk chance:
  • Maple logs: 50.5% base, 40.5% with maximum reduction
  • Elder logs: 0%

While wearing a master cape, the chance of the uncommon material, living components, is multiplied by 1.2 to get 1.2%. The additional chance is removed from the common material, simple parts, giving $99-0.2=98.8\%$.

Thus when disassembling elder logs you should expect to get 9880 simple parts and 120 living components instead of 9900 and 100 without the cape, per 10,000 logs. Junk applies before material distribution, so when disassembling maple logs, you should expect 4050 junk and 5950 non-junk per 10,000 logs, which then is distributed into 5878.6 simple parts and 71.4 living components with the cape, and 5890.5 and 59.5 without the cape.

Example 2 - jewellery

The basic disassembly information for jewellery is:

• Delicate parts - 35%
• Connector parts - 30%
• Smooth parts - 30%
• Precious components - 3%
• Enhancing components - 2%
• 5 materials per item
• Junk chance:
  • Ring of slaying: 4.2% base, 3.4% with maximum reduction

The two uncommon materials are multiplied by 1.2 to give them a 3.6% and 2.4% chance respectively - the sum of uncommon chances is increased from 5% to 6%. The common material chances are then reduced by multiplying each by a scaling factor - $(100-sum\ of\ new\ uncommon\ chances)/(sum\ of\ original\ common\ chances)$; which in this case is $(100-6)/(35+30+30)=94/95$. This then modifies the common chances into 34.632% and 29.684%.

Thus, for 10,000 rings of slaying disassembled, you should expect:

Material	Without cape	With cape
Delicate	16,905	16,727.1
Connector/Smooth	14,490	14,337.5
Precious	1,449	1,738.8
Enhancing	966	1159.2
Junk	1,700
