The new (for me) duergar stronghold, with orcs battling the duergar forces. Getting to see conflict like that among the NPC's was very exciting. Loved it!
The new cloaker spiral and the lore implications of alliances therein? Also pretty dope!
The new loot matrix, as well, has been pretty rad. New poisons? New armor for shadowdancers and assassins? Fackin' rad!
Can't wait to explore the rest of it
Kudos to all the dev's and code contributors. Ya'll rock.
