Hello, Thanks again to the development team and their hard work.
I am opting to use this thread to report this issue to help document the issue and hope that is also preferable to those working on the Patch to document tests and neatly organize them here.
Wizard - Bladesinger: Bladesong has an issue where the Bonuses for AC, CON Save Throw, Movement are all not applied. Here is a quick upload demonstrating the issue:
This was discovered last night during a live stream on my channel testing certain changes and experimenting with characters to play through Honor Mode. I am not going to link that Live Stream unless requested out of respect and to stay on focus with this possible mechanical problem with the Patch. Otherwise, I will link if requested and can provide a timestamp when we discover the issue upon testing Monk + Bladesinger and Barbarian + Bladesinger multiclassing. We then discovered the Bonuses do not apply even on a straight forward 12 Levels of Wizard Bladesinger.
It was suggested that there is an issue with the Armor Class recalculating, as equipping armor seemed to have restored bonuses. However, Action Surge on a different character seemed to also restore these bonuses. So, I apologize I cannot personally seem to replicate how or why the Bonuses are restored. I also do not know if this is only happening in Honor Rules, as I reported last Update Pact of the Blade did not grant Extra Attack due to that ruleset having an issue.
I have tested after removing mods, and the issue persists. I will try to make time to starting a new save file with no mods enabled nor installed. I will then play a new save until Bladesong is acquired at level 2 and test and record it and place it here to update.
I did some quick trials, and quickly found it to be pretty consistent.
1: In order to start Bladesong the normal requirements must be filled. 2: To gain the actual benefits, you must have the Bladesong Impeded status.
So start Bladesong, then equip armor or something else that normally prevents Bladesong. A side effect of this is you can use powerful gear with Bladesong that isn't intended to be used with it(such as Balduran's Giantslayer or Armor of Persistence!), provided you've already begun Bladesong.
