Hey there!
I don't know if you're still reading comments on this map, but IMO it's a really great map with very high potential, but it has quite a few weird bugs holding it back for me. Figured I might as well post them if there is any possibility of you reading about them!
First of all, I want to say I've already spent hours and hours in this map. I really really do like it.
(Warning: LONG read)
I took the Adventurer role, I like completing missions. However, the passive states that you get stats from killing Champions. This doesn't work a lot of the time. I only got it to work once in fact, multiple other times it showed a 'tome effect' (like if you pick up tome of knowledge) but nothing happened to stats.
Also, his W states that it reduces enemy attackspeed, but it increases it instead

and his E (the comet) has a very long trigger time so it's basically useless. Also his class skill, the potion, heals for WAY less than it should. Like 1/4 of what it should be. Lastly, his ultimate softlocks you. You can't move or do anything after casting it, but you can still die.
Another softlock happens when you take damage from a Mystic Shrine in the Hive zone. Spawning the enemy and losing 30% of hp is fine, but if you take 200 shadow damage, you cannot move or do anything after.
Some other stuff happens when you transition into/out of subzones. For example, in the Brume Caves I very often get extra items from nowhere in my storage, including the Undead book. This makes doing the quest for the shrine found in the Brume Caves impossible because you sequence break it (have the item before finding the shrine).
If you go down another level in the same cave, you get a quest to kill some leader-type creeps. One of those, the Deadeye captain, stays permanently invulnerable, so I got stuck with him because the gate closed behind me.
Also, the riddles in that subzone don't work. (The answers should be
but no matter where I type it out, it doesn't work). The other riddle with the ancient runestones does work, so I don't know what's different.
Many early quest items disappear if your primary hero doesn't have them in his inventory when you enter the Spawning area. I couldn't do the money gang quest and the letter quest because of this (but did them on different playthough without problems).
If you still have the Warlock from the hunter quest with you and enter Sunken Grotto, he will be softlocked when you exit.
In the Sunken Grotto, after you have the Eye of the Depths and talk to the NPC that gave you the quest, the Altar of the Depths doesn't trigger the next part of the quest.
In the same area, I put 3 books in the sections where they belong (if you put them in the correct section you can't take them out again), but the Bookworm quest doesn't trigger and the chest with the key stays closed. I think that key is for the door in the Spawning area? But I'm not sure.
Some chests are unreachable (top right in Spawning area, top left in Hideout).
If you take the Dream Treasure in the dream quest, you get warped back to reality, but after the floating NPC says her line about the treasure, the game softlocks. You can control the camera, but nothing else.
Finally, there are a few balance issues. Most are arbitrary but there is some game breaking stuff. If you EVER get the Eye of Night or the Lucky Fishing Hat, it becomes impossible to lose. Spellcasts gain free permanent stats. Inside dungeons the Adventurer's potion skill doesn't have a cooldown, and it's always night, so the Eye of Night always works. You can just hold down W key for infinite stat/hp gain. If you don't use Adventurer, the Camera controls count as spells. Just hold down the key for camera up or camera down.
If you ever make a new version, I suggest removing Cursed Coins. They are NEVER worth it. Even if they gave 5000 gold each I wouldn't take them because stats are very hard to get (except if you exploit the items named above).
I'll keep looking out for other stuff just in case!
