This is an unlisted video on my Youtube channel. I have documented a short fresh run using Honor mode and reaching level 5 with all 4 subclasses of Warlock. All 4 have Pact of the Blade at 3, including Hexblade subclass which was noted in the Update 2, requires this level 3 choice to receive the level 5 Extra Attack from Deepened Pact.

This video is just a clip at the end of the streamed/documented playthrough to get to the point:


This is a stream for my members section but the stream itself was setup to casually (and sloppily) get to level 5 with 4 Warlocks on the Honor settings of the game. So that there is a full documentation available to show what steps I took.

Hexblade, and any other version of Pact Weapon's Extra does NOT appear to be working.
I have currently no mods installed or in the directory. I am using a fresh re-downloaded version of the Stress Test copy of the game and I am playing on Steam/PC.

I hope this reaches the development team to help assist with resolving bug errors. I am not used to play testing and have simply tried to just document the consistent issue I have while using the Stress Test version I obtained from a kind viewer on my channel and asked if I would be interested using a bonus code to help give feedback and report issues like this one here. If you believe I have missed a crucial step in using the Pact Weapon Extra Attack feature, or more generally have questions to my testing, I am ready to help out and will check back in here for any responses.

I have a lot more feedback I would like to submit, and more importantly, I would like to see the viewers of a recent video of mine have their feedback in the comments section possibly be considered with some of the changes seen in the Update 2 of the Stress Test. Thanks for your time.
