Tracking down a full completion run in Hollow Knight: Silksong can feel mysterious at first. The game does not openly explain what pushes its internal percentage higher, and many players only discover the system after obtaining a particular item. Once the Farsight item is found and placed inside Hornet's Bellhome, the current completion status becomes visible, but the exact requirements for the Completion achievement remain hidden. This guide walks through the categories that matter for a 100% run and clarifies which activities do not contribute.

In the original Hollow Knight, reaching 112% completion required collecting every Mask Shard, Vessel Fragment, Charm, Nail upgrade, equipment piece, and spell. Players also had to defeat progression-related bosses and clear miscellaneous challenges such as the Colosseum of Fools. Silksong follows a similar philosophy, though its own checklist has a few important differences.

As of the current version in 2026, the completion route remains focused on collectible categories rather than raw boss count. To earn 100% in Silksong, players must still find every stat increase item, every Needle upgrade, every ability including all Ancestral Arts and Silk Skills, every Crest, and every Tool in the game. Upgraded versions of base Tools are not counted separately, so acquiring the base Tool is enough.

The main difference from the original Hollow Knight is significant. Silksong does not require players to defeat every boss, nor does it require completing every Wish. The only bosses and Wish quests that matter for completion are those connected to one of the items on the checklist.

For example, the Broodfeast quest must be finished because it rewards the Longnail. The quest itself adds no percentage, but the Longnail does, so the quest becomes mandatory for a true 100% run. A similar rule applies to many side activities. Individual Fleas do not count toward completion, but finding 25 Fleas is one of the requirements to enter Act 3.

Progression goals follow the same logic. Players will not earn percentage for acquiring each piece of the Threefold Melody, nor does each collected Map provide any direct progress. However, because these objectives are required to reach Act 3, they are technically unavoidable on the road to 100% completion. In short, some tasks are mandatory because they unlock required items, even if the task itself does not move the percentage.

The table below summarizes what counts and what does not.

Players looking to 100% Silksong should therefore focus on collecting every permanent upgrade and Tool rather than trying to clear every boss or complete every Wish. Keeping track of the Farsight display can help confirm whether a missing percentage is tied to a stat item, an ability, a Crest, or a Tool. The system rewards thorough exploration, but it does not punish players who leave optional bosses or side Wishes unfinished unless those activities guard a completion item.

A full completion journey still requires careful attention. The list of required collectibles is broad, but the distinction between direct percentage and mandatory progression is useful. By locating the Farsight item early and placing it in Hornet's Bellhome, players can monitor their status and plan routes through Act 3 more effectively. The path to 100% is not simply a boss rush. It is a scavenger hunt through every upgrade category, with a few progression roadblocks that must be cleared along the way.

For players who find this kind of meticulous completion tracking satisfying, the hunt doesn't have to end with Silksong. Many similar action-platformers reward the same level of thorough exploration, and building a library of such games can quickly add up.

After you've finally hit that 100% mark in Hornet's journey, having a few more games lined up at a budget-friendly price keeps the momentum going. Whether it's revisiting other metroidvanias or tackling entirely different completion challenges, saving on the games themselves just makes the next 100% run even sweeter.
