Very fun adventure with a variety of enemies. I woudl say that the three dwarves that accompany the party make the encounters a little too easy (provided that they all survive). I would recommend avoiding them as combatants when possible (excluding the orc battle of course), especially during the encounter in the shrine. The shrine encounter in particular can be easy for a party (I ran this with a party of four) with all the NPCs that can jump in. Granted, a good hit from the spiders will one shot an NPC, but the phase spiders have crap attack bonuses (only +4). I would like to see that encounter made more difficult by the addition of a third enemy unit that has a low damage expression, but high attack bonus. Just to put a little extra fear in the NPCs. Maybe some kind of custom phase spiderlings? They could even burst out of an egg sac that was laid inside the dead aarakochra. Despite my criticisms, this is a great adventure and I recommend using it. Great work!
