Stone Hammer

The Stone Hammer gives the Defender an AoE knockback slam that triggers every 8 hits. The slam sends nearby enemies flying backward along their path, interrupting their forward momentum and temporarily removing them from melee range. It's a useful early-game crowd control item that buys extra time for your Archers and Healers to operate — but the 8-hit cooldown means its actual impact depends heavily on your Defender's attack speed.

How the Slam Mechanic Works

The Defender tracks a hidden hit counter while the Stone Hammer is equipped. On the 8th consecutive hit, the counter resets to zero and a ground slam triggers centered on the Defender's current target. The slam deals bonus physical damage to all enemies within approximately 2 tiles of the slam location, and knocks them backward along their path.

Key slam mechanics:

Knockback Double-Edge
Knockback has a hidden downside: enemies knocked back must re-travel the path to reach your Defender again. This extends their time on the map — which can be a problem if it allows enemies to survive longer and deal more damage to other parts of your defenses. Use Stone Hammer intentionally; random knockbacks can sometimes work against you on tight timing maps.

Attack Speed and Slam Frequency

The more frequently your Defender attacks, the more frequently the slam triggers. A Defender with a standard attack speed will slam approximately every 8–12 seconds in normal gameplay. If you've invested in the attack speed skill tree nodes or equipped a Swift Helm, the slam can trigger every 4–6 seconds — nearly doubling its crowd control effectiveness.

This means the Stone Hammer scales with attack speed investment in a way that the Ban Hammer's 15% proc chance does not. If your build focuses on fast-attacking Defenders, the Stone Hammer's effective slam rate becomes genuinely competitive.

Synergy With Ban Hammer

Equipping both the Ban Hammer and Stone Hammer on the same Defender creates a powerful dual-CC kit:

This combination is one of the more durable Defender setups for Round 20–60 in Endless Mode — the consistent CC chain keeps your Defender alive even as enemy HP scales up.

Item FAQ

Does knockback affect bosses?

Yes, bosses can be knocked back by the Stone Hammer slam, but the knockback distance on bosses is reduced (approximately 0.5 tiles vs. 2 tiles for regular enemies). It's a brief interruption rather than a meaningful repositioning. For boss fights, the Ban Hammer's stun is generally more impactful than the Stone Hammer's knockback.

Does the hit counter reset when switching items?

Yes. Equipping or unequipping the Stone Hammer resets the hit counter to zero. Avoid swapping items mid-wave if you're close to triggering the slam.

Does the slam damage scale with Defender level?

The slam's AoE damage scales with the Defender's base attack damage, which is improved by the skill tree. Investing in the Defender damage skill tree nodes improves both regular hits and slam damage simultaneously.
