While I was skimming it to get the monster mini count, I noticed several things.
1) A few skill challenges. (Locating the Great Warren, activating two portals, one of which is to the Feywild, etc).
2) There are a
lot of encounters here. There are a few I'd personally swap out for others.
3)
4) Barely any traps. Although one of the additional encounters that's in the DM booklet has a cool reflavoring:
Spoiler:
Some shambling mounds and stormrage shambling mounds are hunkered beneath some lightning-enhanced trees. The trees are laced with veins of mythical metal, and are treated as a Fire Jet trap that does lightning damage. Also the trees are mildly magnetic, treated as daggerthorn briar (
DMG 89, 300xp) that only effect heavy-armor wearing characters.
I would like to see more of this reskinning to give a fantastic appearance more often.
