My thinky-thoughts for the loot...
1 Ustalavic Silverware - I don't know what this is. If it's just random stuff like jewels and the like, then SELL
1 +3 Greatsword - Tess is the greatsword user, but honestly, I think her +2 Feybane greatsword is better for her overall. Presuming we encounter more Fey.
8 Green Spinels - SELL
1 Art - Probably SELL ... unless it's awesome and we can hang it on our walls back at the castle.
1 Cloak of Resistance +3 - Good for everyone.
1 Headband of Mental Prowess (+2 INT, CHA - Gives access to Knowledge Planes) - My first instinct is to give this to Tess since her channel DC is based on CHA ... and the INT bump brings her to average intelligence ... but giving it to J'varis might have greater benefits as he's the sorceror...
1 Oculus of Abaddon [Evil] - Evil so DESTROY
2 Ring of Protection +2 - Good for everyone.
1 Phylactery - DESTROY
1 Dark Blue Ioun Stone - Not sure what this does ... let's see... if
this is the one, it provides Alertness (+2 to Perception & Sense Motive). Hmm. Walker or Melikova, I'm thinking. Probably the latter since that bumps trapfinding...
1 Ring of Friend Shield (Match w/ Previous) - Hmm.
Since Andrei is mostly the tank, he should probably have one since this can halve the damage one character takes & the other takes the rest. As to who gets the other half ... man, that's tough. Heh. Can he have both so he can give the other one to Liliya, soon to be Lady Voronkov? ETA: Actually, Andrei already has two rings - freedom of movement and sustenance - so he can't use this one that I'm aware of.
1 Cloak of Resistance +1 - Good for everyone.
1 Gloves of Swimming and Climbing - Who is our climber? This might (logically) go to Melikova?
3 Dust of Dryness - One of you casterly types should nab this, I think. Can totally see Walays taking it, then abusing it in some fashion...
1 +1 Cold Iron Magical Beast Bane Flail - Damn. That's not terrible ... but nobody uses this kind of weapon so ... probably SELL
1 All Tools Vest - That's neat. Do we have anyone who Crafts stuff?
1 Ki Mat - Gosh. I wonder who should get this one? Maybe ... Walker? Or Walays?
1 Sheath of Bladestealth - This is a pretty interesting magic item that is screaming Melikova or Walays.
1 Bracers of Armor +4 - J'varis, I expect. The rest of us wear armor. Although ... if he mage armors in the morning and it's better than this, Walker may consider taking this so he doesn't have to wear armor at all...
1 Belt of Mighty Constitution +4 - Andrei or Tess, I suspect, since we're the tanks.
1 (Bag)Pipes of Pain - Andrei. So he can destroy them before Walays ... shit.
1 +2 Fullplate - Probably Tess. Andrei can (and eventually will) wear Heavy Armor, but only if it's mithral so it counts as Medium. His Cavalier archetype (Emissary) allows him to move at normal speed when wearing Medium armor, so donning this would slow him to 20...
1 +1 Heavy Wooden Shield - AFAIK, Andrei is the only one who uses a shield and this bumps his AC up by 1.
1 +1 Breastplate - Andrei already wears a breastplate, but it's only MW, so unless someone else claims this (unlikely, I think), he'll nab it.
1 +1 Light Crossbow - Do we have anyone who uses a crossbow?
1 +2 Leather Armor - Walker is (I think) currently wearing +1 leather, so donning this jumps his AC by one.
1 +1 Boar Spear - Walays uses a boar spear, doesn't he?
Wasn't there talk about a lesser rod of Quicken Spell also?
ETA: We also have that spellbook from the phase spider that we don't know what is in it.
