Tested as thoroughly as possible, even going so far as to bring a second swordsman to make sure it wasn’t just the Stun duration running out.
Mind you, the stun should last 2 seconds at least, as it is right now, even if it worked, it’s impossible to make use of it with Thrust or Pommel Beat as the stun is over before they connect when trying to do so on your own.
Restrain does NOT let other skills make use of the Stun effect for bonuses right now. Will add to the post later demonstrating other stun sources triggering Pommel Beat and Thrust’s bleeding just fine.
@GM_Erick Decided to make a new thread because of the additional testing I’ll be doing. And since this glitch has been around for quite some time (though most people thought it was Thrust, which it isnt), I posted it in Unresolved.
