Date & Time: April 13, 2022
Frequency: Always
World name: Tiamat
Character name: Ryuuka Zekken
Class/Level: Paladin / 90
Party or solo: Party / Solo
Area and coordinates: All PvP areas including Wolve's Den Pier

Steps:
1. Use Paladin
2. Use Intervene to target
3. Stun status not applied
*Shield Bash stun status working correctly (3s), however Intervene is not working as written in the tooltips (Additional effect: Stun, Duration: 2s)
This is game breaking because it makes Paladin very weak.
Fix this as soon as possible

Seconding this, tooltip states it has a 2 second stun but it does not apply any stuns, it only give a single stack of Sword Oath.
