The Lord of Storms DLC adds a few fun new twists to the game. In addition to the expanded content (a mostly standalone chunk of puzzle-heavy stuff in a new location in the game), there are also some significant quality-of-life enhancements. Characters can be renamed (a minor but flavorful improvement). The Quick Combat feature has had some bugs fixed, and also has an optional flag to disable player spellcasting in QC (you only choose QC when the enemies are trivial in the first place, so you certainly don't want to waste magic resources on it!). There are a couple of new unique items which fill some itemization holes. But mostly the expansion is about the puzzles. Thunderbolt Keep is TIGHTLY packed with puzzles and secrets! A particularly fun aspect of it is that you might think you've explored the keep quite thoroughly initially, and then later you figure out just how much stuff you missed the first time through. There's a lot to find! Good luck!
