All the problems with deviations from the old lore, I feel BG2 wouldn't be worthy of the name by these standards. It constantly deviated and bent rules and retconned stuff from the first game and from the rule books, because like BG3, it adapts things to serve the story and be a better game, not to be a checklist for rules-lawyering
[quote=DumbleDorf]Irenicus just used his magical powers to do stuff. The only reason he got so far is because he had so much plot armor every faction that managed to subdue him didn't kill him, but let him live and overpower them with MAGIC later.
Irenicus had the best voice acting in the history of video games though. David Warner was a star talent (If you haven't watched his Hornblower episode do it, he's amazing as a villain.) He didn't need a good motive, BG2 was about how you get there not the destination, all he had to do was be menacing and seem powerful and out of reach.
