Just did 3 maps on test, details as follows.
Level 6 - Malas, 63.54N 28.32W
Guardians - Devourer of Souls x3, Rotting Corpse x1 (one of which dropped what appears to be a deco item "Playing Cards")
6 LP fails, message of "Gas escaping from chest" - reulted in 0 gold being in chest. Also a message of a "Grubber" spawning and stealing an item. Grubber runs off, almost like a vorpal bunny. You can kill said grubber to reclaim the stolen item (150-200 HP).
New loot:
1x Skeleton Key (10 charges)
1x Tasty Treat
1x Recipe (Rune Carving Knife)
1x Pardon (gold scroll, reduces murdercount by 1)
Artifcact bag containted alchemists bauble.
Spawns while looting the chest = Wanderer of the Void x4 (no loot?).
Actual loot items within in chest, nothin special.
Level 6 Ilsh, 52.23N 17.9W
Guardians - Exodus Minion x3, Gargoyle Destroyer x4, Titan x1 <- one of which dropped "Playing Cards"
3 LP fails, resulting in a "Grubber"
New Loot: Runed Sash of Warding (Sash with properties Spell damage ward / Brittle / 50 Charges)
1x Tasty Treat
1x Creeping Vine (deco?)
1x Lvl 6 map (Ilsh)
Artifact bag : Blazing Death
Spawns while looting chest : 1x Gargoyle Destroyer
Actual loot items within in chest, nothin special.
Lvl 6 Ilsh, 119.38N 65.36W (Really close to valor champ spawn)
Guardians : 3 Titans, 1 Gargoyle Destroyer, 2 Exodus Minions
1 LP fail, no special messages
1x Skeleton Key (10 charges)
1x Scroll of Alacrity (detect hidden)
Artifact bag : Alchemists Bauble
Spawns while looting : 1x Exodus Minion, 1x Titan
Actual loot items within in chest, nothin special
As a side note, all 3 chests spawned with exactly 19 of a random gem (ruby, tourmaline, etc) and 6 SA essences (again seemingly random). Maps 2&3 contained 30k gold, while map 1 was empty (i believe from the gas escaping message).
I did all 3 maps with a template of
110 Myst
110 Focus
90 Mage
90 Med
100 Cart
100 Mining
100 Lockpicking
and found them very straight forward. Actually having to deduce where the chest was, rather than just visiting a rune librabry wasnt a problem, and in all honesty took no longer than having to tab out etc.
So far, I am enjoying the changes
