Legend says this gem was crafted by Zei to torment fleeing enemies. Other legends claim that Zei never existed.
Notes[]
- The bonus is calculated separately for each enemy and each particular hit.
- The stun chance is reduced by Proc Coefficient for every enemy hit.
- This gem does affect the damage done by Pets and Minions.
- Note: Although the in-game description states the damage bonus is for ranged attacks from 10 - 50 yards, in actuality the gem's damage bonus begins at 0 yards (melee attacks) to a maximum 40 yards. Therefore all builds, including melee oriented builds, can benefit from the use of this gem.
Tips[]
- Damage over time effects do grow in power if the enemy flees, or the character ventures far from the target (making the 'hit-and-run' tactics quite efficient).
- A chance to Stun adds some more maneuverability as well.
History[]
- Until patch 2.6.0, the distance was calculated from the enemy to that Pet or Minion not to the Player, but this was changed to player-monster distance in 2.6.0.
