Anchor Chain

Anchor Chain is one of 's aura s in Xenoblade Chronicles. It gives him immunity to all sorts of knockback, continuously generates 200 permanent aggro per second for the duration, and stops Reyn from losing permanent aggro when taking damage.

Overview
Anchor Chain is much like Rage in that it gives Reyn a way to be useful without having to successfully hit anything - specifically, it gives him permanent aggro for free, as if he is continuously dealing damage to every enemy in the battle. Making him immune to aggro loss via damage is arguably even stronger, as having to fight through hits to keep aggro is one of Reyn's downfalls - if the art runs to completion, Reyn's aggro per enemy is now raised by at least 3000, and he didn't have to do anything. The knockback immunity is more situational but quite useful, especially against the many arts that blast the party away from each other, allowing Reyn to ignore the knockback and run around to help everyone if they are now dazed.
