Delver's Drill is a Red tool that sends Hornet straight down, dealing damage to enemies in the way in Hollow Knight: Silksong. Check out how to get Delver's Drill, its location, and its effects here!
List of Contents

Players can find the Delver's Drill in a hidden location in the Underworks. This section is blocked upon entry because of the floor, so players will have to clear the first half of the vertical section and activate the right levers.
Players need to hit a lever to release the block that will open up the lower area of the Underworks, then open up the hidden area by hitting another lever. These levers aren't hidden and require little backtracking.
The first lever can be found after clearing the first half of the vertical section. This also provides a shortcut for players to access other areas of the Underworks and Citadel without having to take the original route.
From the first lever, you can drop straight down to avoid enemies. The second lever can be found in the lower section of the Underworks, after you have activated the first lever.
The Delver's Drill is a more powerful version of Hornet's downward slash. This can deal great damage to large enemies and bosses with a well timed activation.
