What I needed

My Adventurers had been trudging through the same campaign for months now. I needed to refresh their spirits and break up the same ole routine. This one was perfect for them. A pc in the group was part Drow and I wanted the rest of the group to see what most other Drow were like. They are very committed to their adventure but loved this one shot. I will be throwing in more of these one shots from Arcane Library more often.

Great One Shot

Wow! I needed a one shot for my party since one of the PCs couldn't make it for our main campaign. I had seen the Arcane Library on FB and didn't think much about it. I was agonizing because I couldn't find anything I liked on other sites. I saw that one shots here were only $2.99. I bought this one and a few others. The prep was amazingly simple and my players LOVED it! The boss battle at the end was TOUGH and almost had the party TPK'd but they overcame and did well! I would 100% recommend this product to anyone in need of a quick one shot. I can't wait to try out the other ones I bought and will be buying more soon!

Solid Adventure - Easy to Run

We really enjoyed this 1 Shot.

It was a memorable adventure. I really liked the setting, NPC encounters and the combats, as they were all pretty interesting (using environmental factors). The enemies and NPC's had distinct personalities too. Using Roll 20 for the first time, we had a solid experience with this 1 shot.

The only things I would improve are: 1) The Map Style: hard to size correctly for Roll20 (because it's hand-drawn), 2) From my understanding, the Chimera that was here was NOT friendly towards the Drow? However, they are close together in a large chamber without attacking each other for some reason...

In the grand scheme of things, the little things didn't take much joy out of the adventure. Overall, I'm looking forward to DMing another Arcane Library 1 Shot for my group.

This is good feedback -- I just updated the adventure to have a brand-new, Roll20-optimized map file! :)

Players really enjoyed

I used this adventure as part of my homebrew campaign and it ran smoothly. All of my players enjoyed it! It was really easy to run and all of the tools are very easy to use.
