As promised, I wanted to update the loot I've seen. They appear to have about 1600 hp (based on adding up my nuke damage from battles).
The most common drop appears to be a silver ring. The next in line is probably a stonefruit.
Some type of gem also dropped often. I've seen a rose quartz, jasper and bloodstone (as well as Carnelian already mentioned).
The Lave Pears were not as common in my run, but they did fall.
I also saw at odd times Words of Spoken, Rune of Proximity and Rune of Fulguration. I'll note the Rune of Fulguration does not stack with other Runes of Fulguration (I've found two types of these runes so far. Perhaps a lower level loot and a higher level loot).
