What Clockwork Heart does

+20% Sentry attack speed. Max +100%.

Clockwork Heart is a legendary chest item that raises Sentry Fire Rate for Sentry 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 Clockwork Heart

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 legendary 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 Clockwork Heart.

Skill

Clockwork Heart and Sentry

Sentry

Summons a crossbow sentry. Watchman’s Sigil adds another, up to five.

Without Sentry in your build this item does nothing, so take the skill first and wish for the item once the skill is upgraded.
