Thank you for your very detailed and thorough feedback. I will work on bugs as suggested, but unfortunately, this is not high on my priorities right now. Since this was my first attempt at using the DM, I started changing/improving things as I learned how it worked. There are probably some inconsistencies as a result. The quests/events after the orc quest are still very much a work in progress. The pieces are there, but there are probably many things that need work. I thought everything up to concluding the orc quest was solid, but I will take a look as time permits.

Forgot to add: When Historian Albrecht sent us up to get the key, there's no key in the closet. I think that's because in the quest step prior, "Return the Rubbings and Crown," he took the rubbings and crown and sent us for the key but the Return part never completed and still shows as active. I'm guessing it was supposed to spawn the key?

Finished this today, enjoyed it, and gave it a tentative thumbs up for a work in progress. Party of four, using UB.

I don't know how much work you want to put in this with Solasta II on the horizon but I'll start with bugs, then things I liked, and finally things that aren't my particular cup of tea.

Bugs:

1. Valerie didn't remove pelts when I turned in her quest. I happily sold them for gold but I don't think that's intended behavior.
2. Mathias' quest for eight spider silk didn't remove silks either.
3. Speaking of Valerie, I persuaded her to sell me her items for the pelts and 500 gold, even though I only had 24 gold on me. She took my 24 gold. Probably need a dialog check that greys out the 750 and 500 gold options and instead says, "I'll come back later when I have enough," or some such.

4. Mathias' Coyote quest didn't complete in the quest log even though he said it was complete and started me on the next quest. I had to complete it with the in-game debugger.
5. Starting a fight in the dialog with the Thugs by the docs near the brothel doesn't actually trigger a fight, they stay green. ("Get 'em boys!!" ....collective shrug)
6. During the first fight in the orc event, the cut scene dialog with Mathias triggered after killing the second orc shaman even though the fight was still in progress.
7. There's no dialog from Issac to go see Granny Smythe after the rescue. I figured she was next since she was standing right there.
8. In Reunite With Ivetta, it doesn't tell you where in town she is. There's only a few places to check, but still.

Things I liked:

1. The orc sequence stood out as good story telling, a heroic call to action, and a sense of urgency. Would have love to see more of that in the rest of the story.
2. Multiple travel paths between load screens as they became available, but I wish they were more consistently implemented.
3. Fast travel, although honestly for as little as the other locations were fleshed out it kinda felt like they should have just been included in the settlement. I do like that fast travel gives a legitimate opportunity to craft.
4. Weapons were very good without being overpowered. Just +1 to hit/damage but the extra effects and secondary damage types really made them fell like something special.
5. The herb bag was great, but by the time I got it I honestly had gathered more herbs than I could use.
6. The availability of NPC help for the tough fights, and in ways that make sense in the story.

Not my cup of tea:

1. Fetch Quests.
2. Killed some pests for me? Great! Now go kill some more.
3. Merchants that buy your stuff at different rates. Feels bad when you find one later with much better rates after you already sold hard won expensive items for a fraction that you could have got.
4. Excessive use of ambush spawn mechanics. A few are good to keep players on their toes but this felt like four out of five encounters were ambush/spawns.

Suggestions:

1. If a fight can be avoided by speech skills, it should also award XP. Yes it's easier but you don't get loot either.
2. There should be a warning to not attempt the crypts prior to level 5. Maybe don't make the brown brothers available until then.
3. Crafting.... needs work. If I hadn't added recipes via UB I don't think I could have crafted anything beyond potions and ranged ammunition. Even with UB recipes I could only craft a few +1 armors and weapons due to almost zero crafting gems provided or found.

Good luck and looking forward to the rest of the adventure.
