Cybele, you do recognize the Golden Eagle. You saw it once when you were present during a meeting between Marc Antony and Herkules. From what you saw, it seems to be a symbol of Rome.

You could destabilize the rock with a big enough blast to cause the Ridge to fall, It would have to be a BIG blast and would definitely make the Minotaur aware of your presence but also give you time to pick off Drogon if he were to collapse down the cliff with the tent. 

It's a 150ft straight drop onto rock from the Ridge and to get back up to the ridge or walk down to where the rocks are would take 30-40 minutes. So if he is caught in the blast, He would take 15d6 fall damage and be separated from his guards.

Plus I would add on 3d12 piercing damage from the rocks below. So he would take a hit before the battle even started, although the blast to cause the Ridge to collapse would be at least a Fireball or a well aimed Call Lightning. 

Pass without Trace has worn off by now. Cybele saw the man walk toward his horse and get onto it but turned to fly back before she saw him leave.

Drogons tent is by itself on the ridge, the other tents are more into the wooded areas. If you were to destroy the ridge only Drogons tent would be affected by it.

Dicaeus smiles at the idea of crumbling the cliff side. “I can put out some pretty serious explosions if we want to destabilize the rift, and that’s just me. Cybele, you have a connection to the earth, could you do something perhaps?”

[ OOC ] I could use Hallucinatory Terrain to make the edge of the ridge look further away then it actually is and maybe we could lure him or some of his troops off the edge.

Edit:  Unfortunately I don't have any earth moving spells prepared. The closest thing I've got is Earth Elemental shape, but I'd need to rest for an hour to be able to use it. If we want to go the route of destroying the edge of the ridge I could do a 5th level call lightning and see if that does the trick.

Carrus nods as Dicaeus speaks.  I like it.  Get Drogon on the ground.  Maybe the drow too.  How long before the rest get to us?  He aims this question at Cybele, who has seen the layout of their target.

"I suppose that settles it then. Drop the mountain and finish off the wounded creature, then thirty minutes is plenty time to get out before the rest get here. Also, perhaps Cybele can fly back up after we kill him and raid the camp for information on the Drow? I doubt that they'll leave a single man behind when they see their leader tumble over the ledge, so she should be safe." Anax is drawing in the sand with his xiphos as he speaks, "Carrus, you and I prepare flanking positions on either side of where we expect the bull to fall. Dicaeus and Cybele, you hang back and find some high ground. If you can keep him held in place or make him easier to hit, you'd be doing us a huge favour. If he's tougher than we anticipate; Cy, you may have to go bear-mode and give us some back-up." As he finishes the sentence, Anax stabs his xiphos into the sand where he draw a pair of horns to signify Drogon, then holds his hand palm down over the sword in the middle of the huddle. "Are we agreed?" He locks eyes with each in turn.

"If we get him off the edge of the bluff? Unless they have magic to let them fly we could finish him off before they can help him. I'm hesitant to do anything that could destroy the tent. If Rome is involved in this I want to bring any documentation we can back with us. I could use magic to make the edge of the bluff appear further away then it is, though I'm not sure what we could use as a distraction to lure him over to fall."

Carrus shrugs at Cybele.  Bring the tent down too.  Papers will survive the fall.  Kill the drow and the beast, take the Roman dog's papers, and go.  Carrus reaches over and puts his hand on Anax's.

Dicaeus sticks his hand in as well. “Agreed. Bring down the cliff, kill the king, gather information, and then return to Athens. And Cybele? Remember that Theseus wants the head. There’s no point to all this if we forget it with the rest of the corpse.” 

Cybele will place her hand in the center as well. "Very well, let's get into position at the base of the bluff."  She will once again cast Pass Without Trace to hopefully keep their approach hidden.

Stealth: 21

Alright, New stealth checks please.

Carrus's stealth check: 22

Anax positions himself close to where he believes that the rock will drop, opposite to Carrus. He'll push himself back against the rock, attempting to hide in the shadows, and will draw his shield and spear ready for an attack.

Stealth: 27

[OoC]: Readying an action to attack Drogon as soon as he lands in front of Anax.

As opposed to walking up the remainder of the trail, Which would have taken another hour or more. You cut threw the trees, they are all young oak and spruce with an occasional yew but nothing older then 15 years. 20 minutes pass before you exit the treeline to the drop point of the ridge. There is a wide open section, 100 feet across and 50 foot wide from the base where there are no trees; But hundreds of sharp and jagged rocks. Approaching you see pieces of bone and some rusty, long forgotten weapons. You now understand why this area is called DeadMans bluff as it seems to be a place where people take their own lives.

Anax splits from the group and heads right, finding a nice spot where he can easily charge forward but remain somewhat in shadow. Carrus goes left and hunkers down next to a bigger rock, with a clear line of sight to Anax. The cliff face is completely sheer, a true 90 degree angle and the ridge above looks like it could be brought down with a well placed blast. Looking up its roughly 150ft to the ridge, which overhangs 10 feet or so from the rest of the hill. 

If Dicaeus uses Fireball. I also want a Perception check from Dicaeus.

If Cybele uses Call Lightning. I want a Nature check. 

Ok, Who's blasting the cliff? 

FYI: This area is considered Rough Terrain. You can move at full speed if you want but you will take 1d4 piercing damage.

[OoC]: is there any way that us non-casters can assist to give them some advantage?

You could Help and give them advantage but you would leave your current position to do so.

[OoC]: I'll stay put.

Carrus will go help if he can.

Stealth: 37

Dicaeus sneaks into position, and once everyone is in position, he waits for a signal from Cybele. In unison with her, he launches a third level Fireball at the cliff face, aiming for any structural weak points he can see.

Perception: 13

Damage: 33 Fire

( I think Call Lightning might be the better bet here since it's concentration and I can blast the cliffside multiple times with just one spell slot if I have to. )

Nature Check w/ help and Guidance: 11 + 4

With a wild looking grin, Cybele will raise her hands as a storm cloud begins to form as she casts Call Lightning at 5th Level. She will draw her fist down in a sharp motion and a bolt of lightning will arc out and strike the cliffside.

Lightning Damage: 21
