Two quick feedbacks:
Overall: Good job!
The battlefield shenanigan is super fun!1) SPOILERS: The level design of the minmir coast could use tweaking. The broken bridge at the end is very anticlimatic, has only marble as a reward (poor reward), no boss, and then involves enormous backtracking. It could use a lasso leading to a portal, or something that loops back to the beginning. If no looping, then up the reward (another quality chest) or put a second boss in the area.
2) This extension uses "new" "newish" and "super old" ennemies. While not a problem in terms of challenge (it works well together), the reward side is broken. The super old need to be tweaked to either be simpler, or give more xp. But as it is the old foes are both way more difficult AND give much less xp. It makes for a disappointing challenge <=> reward ratio. So long story short: buff the xp reward of the old dudes (evil wight, specters, evil dead, etc). Or people will never go there beyond the initial discovery pleasure. Fighting undeads is hard for most folks (debuffs, no crits, etc), so the reward should be there
Good job anyhow!
Cheers!
Ps: haven't done the castle yet, will edit when I do.
