What Whetstone does
Blade Sweep and Shadow Dagger reach 10% farther. Max +40%.
Whetstone is a common chest item that raises Melee Reach for Shadow Dagger only. It lasts for the rest of the run. The item text names how far it stacks; every copy past that point is wasted, so reroll it or wish for something else.

How to get Whetstone
Chest items drop from treasure chests out in the wilds — spend gold to open one, and each chest costs more than the last. Rarer items are rarer drops, so Luck (from Fortune or the Censer) makes a common pull more likely. On every floor’s plaza the Wishing Well grants the exact item you name once per floor: the surest way to complete a build around Whetstone.
Skill
Whetstone and Shadow Dagger
Shadow Dagger
Blades orbit you, striking anything they pass through.
Without Shadow Dagger in your build this item does nothing, so take the skill first and wish for the item once the skill is upgraded.
