Hi there! I just reached Level 10 with my College of Swords Bard, and noticed that Mirror Image was not one of the spells available via the Magical Secrets feature.
In Tasha's Cauldron Of Everything, the new optional rules added Mirror Image to the 5e Bard spell list, and it's the first Level 2 spell I picked up for my College of Swords Bard I'm playing as in my current tabletop D&D campaign (who I recreated in BG3). I wasn't totally surprised that this wasn't included as a base Bard spell in BG3, but was expecting it to be something I could still learn through Magical Secrets, and was disappointed that this turned out to not be the case. I remember seeing in past patch notes that some more spells have been added to the Magical Secrets for Bards since launch, so I assume it's possible to continue to add more.
As Mirror Image is already a Bard spell in 5e's Tasha rules, I'm hoping this is something that could be changed for BG3 Bards in the near future by either adding it to the Bard spell list directly or making it a accessible through Magical Secrets.
