Same.

You all descend further below (I assume you have some way of crating light?) 

After about an hour LANDMOP is able to identify all of the magic items, which are:

Javelin of Lightning

Ring of Jumping

2 Potion of Healing (Greater)

The 5 purple potions are Potion of Mind control (humanoid) but you know that they’ve been altered so the drinker won’t be under your control, but someone else’s.

And finally the Spear is a magic item called a Satira Lense, a weapon from Salorna. It is a +2 weapon that allows the user to attune with it psychically and shoot psychic rays out of it. However, LANDMOP identifies an entity inside the lense that seeks to control whoever attunes with it. If someone wishes to use the spear without being controlled, they would need to battle the entity on its terms; likely in some kind of psychic battle.

Ill let you all discuss the use and management of the items before we descend fully into Khyber

LANDMOP emerges from the bag with the items in tow, sharing the information above with the group. "I believe I may be able to best the spear if you would all allow." It says honestly seeing the benefit of having another ranged option

"I definitely don't need to psychically fight a spear," Elero says, "so I'm good with you keeping it. And I don't need them, but I have torches for whoever does," he adds, pointing to his pack. "Just let me know."

LANDMOP will attempt to attune with the spear after their next long rest

Zoveldra nods. "I don't need the spear, so I am happy to entrust it to you, LANDMOP. Just let us know if whatever is attached to it starts to become too much." She then looks to Elero while tapping her pack. "I also have an everbright lantern, though it is a bit too bright to use if we are trying to move unnoticed. I will probably only take it out to help see if we get into a fight."
