ToME: the Tales of Maj'Eyal

In my current game (1.2.5, Mac, Steam), I found a Fragmented Essence of Harkor'Zun on standard Daikara 1 in the middle of a huge pack of enemies right at the beginning of the level (see screenshot). I've never encountered it before, but from the forums I gather that several spawn together, then the last one you kill becomes a boss. However, I cleared the level without finding any other Fragmented Essences. I know the can do some weird pathing because of rockwalk. Fortunately, I'm playing a Wyrmic, so digging out an entire level is pretty easy. Unfortunately, I pretty much dug out the whole level without finding any other essences (see screenshot).

The latest posts I found on the subject were from 2013, and nobody actually dug out the whole level. I'm wondering if this is an actual bug, or if maybe now the essences can spawn in different zones. If not I'll just put this in the bug section.

As an aside, is there any way that I could try to go for the unlock? I haven't gotten Stone yet, and I'd very much like to. Plus I've lost two nearly-identical Wyrmics to Urkis (never gotten anyone past him), so having just cleared Daikara my window for figuring this out is probably pretty limited.

1) have you tried to "track" him?
1.5) this game is not bug free, every now and then a boss is missing (like the "wife" in the dream or somewhere mentioned "master")

2) there is a text file with all the unlocks if you know the "key" you can unlock whatever you want (except donator mode obviously)

3) urkis (the tempest right?) has powerfull spells that HURTS, but he is not all that powerful, if you can disable him, he is easy to kill.
but keeping him disabled, may be a little difficult where there is a rare frost giant right next to him, so as i mentioned in another topic, get gauntlets of dispersing, to knock of his hurricane and thunderstorm sustains, and stun him to keep them from cooling down.

I've encountered this bug a couple of times myself, though I never dug the level out trying to find the other fragments. Basically all I know to do is report it and move on.

As a side note for Urkis as a Wyrmic, status effects are pretty solid against him from my experience. The confusion from Bellowing Roar and the blind from Sand Breath can really hurt his ability to damage you if chained, and at the least will help clear any trash he spawns with.

Be sure to have some damage mitigating/healing infusions/runes, and maybe a wild infusion that clears magical effects. Lightning Speed makes you practically immune to his damage while in effect; consider it for chasing/running.

As always anti-magic can make you much more durable against mages.

Good luck!

There's a standing bug where enemies that spawn in tight clusters sometimes get placed on top of each other, making some of them inaccessible. Installing Bosses Gone AWOL will help prevent this in future playthroughs.

Thanks for the pointers and the mod recommendation! I downloaded the mod, and also pretty much steamrolled Urkis. I guess I can wait on the Stone unlock for a while.
