A long-range delayed stun that is far stronger against airborne targets: the stun lasts longer the higher they are, and their gravity is doubled so they crash back to the ground.
Numbers: 0.5s base stun after a 2s delay, up to +1.5s extra against targets 30m or more in the air; +100% gravity during the stun; 45m cast range, 35s cooldown; +75 Bonus Health
Buy it when
The consensus answer to flying and airborne heroes and to channelled aerial ultimates — buy it whenever an enemy fights from the sky.
Skip it when
The 2s delay makes it easy to pre-empt against grounded targets; it is a poor generic stun.
Gotchas
The mechanics people most often get wrong about this item.
- Gravity effect increased from +50% to +100% on 6 Mar 2026
- The stun from Knockdown is NOT shortened by Debuff Resist (the wiki notes this may be unintended)
- Stun duration keeps extending while the target falls
Problems it answers
- Air mobility — “They fight from above and I cannot touch them.”
- Gap closers and escapes — “They reach me whenever they want and leave when they want.”
- Channelled ultimates — “Their ultimate wins the fight on its own.”
- Long-range poke — “I get chipped down before the fight even starts.”
- Backline assassination — “Their carry deletes my squishies.”
