So I have been using ZM5's modpack to experiment with resurrecting adventurers. Val'Kyr has an interaction that can resurrects and should fully heal.
Adventurers who died and were resurrected while retired remained playable. Adventurer who was killed on his adventure and then resurrected by a different adventurer did not.
Also, there were issues with unretiring adventurers. If they retire in different spots, they seem to return to the first place they retired at.
Last one, an outsider, ended up half the world from where I retired him (And he was retired only once). And since he was killed and resurrected (to heal torn hair) and I forgot to return his stuff, he was naked.
So I was returning to where his stuff is. Made a stone axe, killed a carp and a clefthoof and made a backpack and some clothing.
Then, at night, I was attacked by 2 jungle spiders. Killed one, the other ran.
Next day, I found a Tortollan camp. A bowman from there later ambushed me. I beat him with the stone axe, breaking it, took his bow and after he died also his quiver and 38 mithril arrows.
Then, in the evening, a Kunchong ambushed me. It was a terrible fight. It took about 30 arrows to break it's legs and wings. I ran out of arrows, and ended up beating it with a rock a few times.
But for safety reasons, I started throwing rocks, ticks, slugs and louses instead. It took a break from the fight, killing two giant crows.
In the meanwhile, I devised a plan. I caught it in a ring of fire.
I threw rocks and leaves for a while, then I went, made a new stone axe and used the bones of one of the crows to make a bunch of stone arrows.
I started shooting the Kunchong with those. Then the fire around the Kunchong started to go out.
But at this point, the Kunchong was alive, but not moving. I kept pummeling it with arrows, and eventually it suffocated from bruised lungs.
I jumped onto the tile where it died, picked up the corpse and a mithril arrow that was stuck in it, then jumped into a murky pool. I was steamed, but unburned.
