Chained Leash is an active skill that can be taught to lancers at level 60 and cannot be ranked.
It's also known as "Giga Leash" or simply "Giga" in PVP.
Chained Leash can be preformed with a lance by the lancer within 15m. This skill pulls up to five enemies in front of the lancer, stunning them and giving control against the enemy. In comparison Leash and Master's Leash, it's ability of chaining multiple enemies makes it the most powerful of 3 leashing abilities that the lancer will unlock.
If cast after Challenging Shout skill changes slightly. It pulls targets to front of lancer, not around enemy targeted with leash.
This skill has been nerfed twice. It's cooldown is now 1min 10sec from original 1 minute.
Since August 2018 patch it only pulls 5 targets (previously 6, or 30 after Challenging Shout).
