TL;DR: Shield Stun is the tank's go-to control skill โ€” an instant shield bash that stuns the target for 5 seconds. Every shield tank gets it. Use it to lock down enemy healers and nukers in PvP, and to interrupt dangerous mob skills in PvE.

Overview

Shield Stun is a stun skill delivered with a shield bash, available to every shield-using tank: Paladin, Dark Avenger, Temple Knight and Shillien Knight. The hit stuns the target for 5 seconds, leaving them completely unable to act. It's one of the core crowd-control tools in PvP and a key part of tanking in PvE.

Shield Stun unlocks at level 20 and improves as you enchant it, raising the chance to land. It also generates extra aggro, helping you hold threat.

How to Use

In PvE, Shield Stun helps when pulling mobs โ€” a stunned mob deals no damage, buying time for Hate to build aggro. It's also great for interrupting a mob's dangerous skills. In PvP, Shield Stun is the tank's main weapon: 5 seconds of lockdown lets your allies focus the stunned target. During castle sieges, tanks use Shield Stun to shut down enemy healers and nukers.
