Silent components are rare materials used in the Invention skill. Level 87 Invention is required to discover them at an Inventor's workbench and use them in a gizmo; however, this level is not required to obtain them.
All Death Lotus items give 3 silent components each, meaning that the cheapest items to disassemble for them is either the inferior hood (tradeable, 30 lacquer), superior tekoh or tabi (untradeable, 20 lacquer each), or darts/off-hand darts (untradeable, 2 ancient bones and 50 ascension shards per 50). (A player can craft extra death lotus darts via the Fletching skill cape perk.) Alternatively, level 9+ augmented (superior) Death Lotus chaps (60 lacquer) give 12 silent components when disassembled, at the additional cost of an augmentor and the time (and divine charges) spent levelling them up.
^The quantity of materials increases by 1 per rank.
^There is a 1% chance to obtain a rare material instead of an uncommon one. The rarity boundaries represent an item with Scavenging 1 below level 20 and an item with Scavenging 4 at level 20.
