Eiren's attack kills thw last remaining gorgon. 

Everyone gets 600 XP.

It will take a minute for Velmine to recover her dagger and Tallis to recover half of his arrows. (Tallis give me a total arrow count in your inventory)

Eiren wipes his blade on the gorgon’s hide. “How are we doing?” He asks the others. 

Corvin shrugs.  "I'm still fine to keep going for a while," he says, looking around at the forest surrounding them.  "And I feel like a forest of illusion isn't a place we want to stay longer than we can help..."

(7 arrows spent, not sure how you want to round that, so either 15 or 16 now post-collection)

Baik recalls his spear. Whew. That's over. Now... Just to be sure.. He looks around for any other creatures. Perception:0

Tallis finds three undamaged arrows (always round down so half of 7 is 3. 20-7=13+3=16).

Baik doesn't see any other creatures in the immediate area.

Here the map again.

Baik remembers seeing a Black Gate 20 feet away from the statue, Eiren also would have seen it.

Velmine is still searching for the enemies, walking around the battlefield, and calling the goat to walk by her side.

"Okay, this is it, I'll just ask them if they have any idea where those monsters went."

She looks back to the party. 

(DM, now that they're dead, there's no illusion hiding them, is there? I'll just add a Wisdom Save, to see if she notices their bodies, hidden or not.)

Velmine's Wisdom Save: 15

You can see the bodies after a minute. (Or before if you want with that roll).

Velmine finds the Gorgon's bodies and then she comes rushing and preparing her rapier to attack, but stops midway when she then notices that they're already dead.

"Oh, uh... Okay, then. Good job, team!"

She goes a bit quieter, a bit embarassed at her own mistake, and starts searching for her lost dagger.

(Wasting the one minute to take the dagger back, again.)

 “No, it isn’t. I prefer enemies eveyone can see to invisible ones.”

Eiren sheathes his sword and mutters with a self-deprecating grimace, “Famous last words...”

Rrr. I hate invisible enemies they're smart. Theres a Black Gate over there! lets check it out!

Corvin nods and heads towards the gate.

As Corvin approaches the Black Gate he sees A ten-foot-diameter circle of runes and black onyx fragments is set into the floor. It exudes wisps of shadowy energy that look like curling black smoke.

Behind the gate on the northern wall you see Glowing glyphs form a circle on the wall about three feet off the floor. You recognize this as one of the contact stones that Syranna talked about.

“These stones—don’t use them to resurrect me if I die, understand?” Eiren tells the others. “I have no intention of ending up undead.”

“Thralls fair In love and war....”. Xavier chuckles at his bad pun.  

Eiren raises one eyebrow at Xavier, saying nothing,

What are you going to do now?

"Well, we know where one of these is now if anyone needs it and wants to use it later.  Let's keep moving."  Corvin heads off to the west.

Eiren (51/63) - 1/2 Bladesong, 1/4 first level spells, 1/3 second level spells. Action Surge. (Your sheet said you had 57 Hp you were at full health before the battle and got hit once for 12 bringing you to 51)

// Using Blessing of the Raven Queen gave me resistance to all damage for that round, so that's why I only took 6 damage. //

"Through the gate, then?" Eiren asks. 

He will approach the black gate and try and use the glyph key on it.
