Looks like Lost Library of Kwalish may adapt well into one of my campaigns with the City of Ooze being a key location for an arc.  I'm just unclear how to read the level advisory "This adventure is suitable for characters of 5th to 10th level."  Does this mean the adventure is designed to run characters from levels 5-10 (and seems a little thin to do that)?  Or could i start this out with 10th level characters, if that's how the sandbox was wandered? 

Any tips, vids, hacks, etc. of it will be appreciated.  I know, one of the big 3rd party presses, Goodman, did a super module adaptation for the Expedition to the Barrer Peaks OG module, if it makes sense to overlap them, or if it seems plausible I'm listening.

I’ve not run it, but I have a couple theories. One is that they just carried over the range from the original 1e module without thinking about it. 
The other is the level depends on which version you play. It give instructions for how to run it as a 1-shot, 3-4 sessions and 6-8 sessions. Maybe the idea is if you are doing the full 6-8 sessions, you start at the lower level and will level up as you go, but if you’re just going to do the 1- shot and skip to the end, you should start at 10?

Yeah I was wondering about that breakdown of adventure lengths relating to level range.  My other thought was maybe this was a "thinking party's dungeon" where it's more about outwitting things and the hit dice associated with levels 5-10 provide enough to make it through a few tough scrapes and suffer the consequence but not out right murdering the party or having a third tier party cake walk it.
