Velmine starts humming to herself one of the songs she once sang in one of her biggest performances as she begins searching for anything of value on the wizard's body.

Investigation 31 (If assuming you'll let me keep the roll I made the last turn the way I asked.)

Xavier mutters "I'm done with these oozes."  fire bolt Attack: 16 Damage: 7

Velmine investigates the Wizard's body and find two scrolls,  another stone on a chain around his neck and a punch containing 23gp. Unfortunately she doesn't find any glyph keys. 

Xavier's Firebolt strikes the ooze and it glows briefly as the fire melts into its essence. 

Corvin, Baik and Qu'oth are up 

Yeah, they’re really annoying me! Baik says as he blasts Sacred Flames once more at the Ooze next to Corvin. This is getting repetitive.

(16 dex or 9 Sacred Flame Damage.)

BP3 dex save -3

The ooze can't avoid Baik's Sacred Flame 

Corvin and Qu'oth are up 

Qu’oth swoops in for a helping flyby, hooting as he harries the ooze. 

Corvin is up 

The Spiritual weapon swings at the ooze as Corvin launches yet another sacred flame.

Attack: 22 Damage: 7

Sacred Flame: DC17 dex or 4 damage

BP3 dex save 4

Between Corvin's Sacred Flame and his Spiritual Weapon, he is able to finish off the last ooze.

Everyone receives 810xp

Because you haven't found any glyph keys it looks like you are going to have to back track to where you fought the big blue creature that tried to swallow someone (Eiren?) whole. Unless you want to try a black Gate?

You can head to either the "Golem Laboratories" or the "Far Realm Cysts"

Thoughts on your next route? I'll let Eiren have the final say.

Before they go anywhere, Velmine would investigate the other two bodies and recover her now damaged dagger. Again, if they possibly have any other weapons, maybe possibly other daggers seeing that wizards aren't known for having expertise in weaponry.

Investigation 23

Along with whatever she'd find, she'd show the wizard's items she found earlier. "Here! This one had two scrolls... Check to see if they're magical, I already know I can't use them... Another necklace, and a pouch of gold... It'd total up to 6 coins for each of us except two of us, who'd get 5." She takes 6 for herself, considering she skipped 2 GP the last room.

Eiren will take a look at the two scrolls.

He also pockets 5 of the gold coins. "Every little bit helps," he says. "This'll buy a few rounds, when we get back to somewhere with no oozes and wizards trying to kill us."

Velmine doesn't find any weapons of the wizard besides the strange short quarterstaff. So she moves to the search the bodies of the two apprentices. Each apprentice has one of those funny looking quarterstaffs along with a dagger. They also each carry a potion. After doing a simple taste test you determine that first apprentice's potion is a Potion of Invisibility while the second carries a Potion of Climbing.

Velmine hands the scrolls overs to Eiren, who reading them silently, discovers that they are a scoll of Identify and a scroll of Thunderwave

Here is a list of items that you haven't identified 

• Necklace with stone from area 73 (Xavier is carrying)
• Necklace with stone from area 72 (Xavier is carrying)
• Armor from area 72 (Corvin is wearing)
• The necklace from this area (70) that Velmine just handed over to Eiren. 

“If we would like to take some time, I can identify each of these in turn,” says Eiren. “Should take about 10 minutes per item.”

 Eiren tucks away the scroll of Thunderwave for later, and immediately uses the scroll of Identify to reveal the properties of the magic necklace he’s been carrying.

("Immediately" actually means 1 minute since that's the time you need to waste to cast Identify, and it's the same when you're reading a scroll.)

Velmine leaves the quarterstaffs alone and picks just the two daggers for a total of 4 with her usual ones. She then shows the two potions. "Take a look at these. This one..." She shakes a vial that seems to be empty even if the sounds of liquid can be heard from it when it's being shaken. "Will make whoever drinks it invisible. And personally, considering the way I do my work, I'd love to use it. The other one will make you a good climber, but I'm already good at that, so I'm not keeping it, one of you can have it." She pockets the Potion of Invisibility but leaves the Potion of Climbing for the party to pick.

(I have the athlete feat, I can already climb walls without wasting any more movement than I usually do.)

Eiren reads the scroll of identity and identifies these four items. 

• Necklace with stone from area 73 (Xavier is carrying) = Transmuter's Stone (Proficiency on Con Saves)
• Necklace with stone from area 72 (Xavier is carrying) = Transmuter’s Stone (Fire Resistance)
• Armor from area 72 (Corvin is wearing) = Chain Mail, +1
• The necklace from this area (70) that Velmine just handed over to Eiren. = Transmuter’s Stone (Acid Resistance)

The three Transmuter’s Stones are my Homebrewed items and so you need to have Homebrewed content checked  under the home section of your character (it edit). You should be able to add them to your character sheets, if not let me know. 

Eiren stands back from the better part of an hour’s work. “Well, these stones are interesting. All you have to do is wear them, and they bestow benefits. This one allows the wearer to resist acid, and this one does the same against fire. And this one, this will give you quite a bit more tolerance to pain. Good for a spellcaster.

 “How’s the armor fitting there, Corvin?” Eiren asks the human.
