That is rather impressive. I'm quite envious, but at least my main Alicia looks better and has more fashionable armor. Or not?

I usually never play magic classes in any game, so I decided to play as Sorceress in my "second" (played only to lvl 10 in my first) playthrough, now in Honour mode, to have some variety. A short time ago, after hitting 12, I decided to try some stuff, so I respecced her to a Bard/Paladin, a bit similar to your build, to see the raw power of this allegedly uber solo build. It was a desaster, a mean mummy and it's minions ripped her guts out with relative ease, and she wasn't solo but with Shadowheart, Gale and Karlach. Neither were the mighty smites that mighty nor was the AC of 30 (26 + 4) of great use.
I obviously cannot play such a build. I respecced to an easy-peasy class I can at least understand a little bit (Sorceress). When I see what you achieve and how much fun such a playstyle can possibly be, I start to mull over it again. My main mental problem with the build is the reliance on Phalar Aluve (which Alicia had in the fight but did not use effectively, I did not activate the singing), as I do not really want to base a build/playstyle on one item.
