OOC:  Never heard of destiny warriors, but looking forward to it.  What are Cleave rules again?  Extra damage carries to next nearby opponent?

IC:
Aino shakes her head.  Not at being marked for death, but at Sorath.  Maybe we should mark him for death.  'Your display' caused waves?  I may have dismembered one captive assassin and killed the other, but it was Sorath who put up the display for the town to see.

Aino's pre-battle preparations:

Casts Water Breathing as a ritual on the whole party (including Thumbtack). Lasts 24 hours.
Casts Comprehend Languages as a 10 minute ritual on herself. Lasts 1 hour.
Casts Rary's Telepathic Bond as a 10 minute ritual on the whole party. We can all communicate telepathically with each other. Lasts 1 hour.
Casts Phantom Steed as a 10 minute ritual. Quasi-real horselike creature appears for either Storm or Kileprat to ride if they wish. 100' move speed along the ground. Aino and Casey can fly, so I assume we won't be using it. Maybe Storm can fly now too so then no one needs it.  It stays at the arena's edge.
Casts Fire Shield (choosing cold shield, granting fire resistance) - takes 1 Action, lasts 10 minutes, no concentration.
Casts True Seeing on herself - she now has Truesight with range 120' including into the Ethereal Plane for an hour.
Thumbtack holds tightly to the Ring of Spell Storing in her claws, containing 2 Silvery Barbs, 1 Shield and 1 Vortex Warp.
Just before battle, Aino starts her bladesong with a bonus action.

(With Aino having Truesight out to 120', if Sorath or anyone else is hanging around invisible nearby, she can see them.)

Nope no invisible people

You had two posts with different options, I am assuming the second post was the finalized options for me but wanted to check before deciding.

 Second post. 

DM:lol ya Sorath total passed the buck to yall on that one

Cleve rules yes any extra damage after you kill will pass on to next enemy.

Okay I will have it ready for final fight with two levels of exhaustion then.

Sounds good.

The next morning arrives. Kileprat has already left. Leave a note

"Went ahead there was something I needed to do.

-K"

The party heads to the arena ready for the final. You arrive in the ready to room with out issue.

The whole city seems to be out today. The enery in the crowd seems to be behind you. 

In the ready room there is no sign of Kileprat. Asking the room attendant he goes and looks for her. Worried, you all push it to the back of your mind, knowing the stakes and the Syndicate won't wait.

Final preparations. I'll kick us off tonight 

Finishing your final preparations the blue portal opens. 

The crowd is going crazy. Across from you is your opponents. The crowd is so loud you can't hear the usual intro Dan gives the fight.

The leader of the Syndicate group raises his hands. There isvacweird hush that falls.

"Garmuk, rules are rules right? Anything goes just no leaving the arena?"

Garmuk nods

The Syndicate leader lifts his amulet. There is a glow then the arena fills with smoke.

As it clears there are hundreds of Syndicate members armed and armored before the party.

Garmuk roars "WHAT IS THIS!?!"

THE Syndicate leader looks up at Garmuk.

"What I did not leave the arena"

Roll Initiative 

Initiative: 6

OOC: Also would have cast bless right at start at level 1 since we are down someone.

You can post anything you would have done at the start.

(oh my!)

As soon as she sees the syndicate leader, she (BA) casts hex (disadvantage str) on him.  She enters flying, 20’ up on her broom.  Other pre cast buffs above   Don’t forget inspiration everyone.

17 initiative. 

Aino Initiative (at advantage due to Shortsword of Warning):  24
(See post 1346 above for Aino's immediate pre-fight preparations).

Casey, before the fight, did you cast Aid and use your Inspiring Leader for Temp HP as usual (I know you did the Bardic Inspiration)?

@Bushawk:  How wide (laterally) is the Arena?  Also does it look like the hundreds of Syndicate soldiers have a way to fly?

Aino calls out:
"If the only rule is no leaving the arena, but summoning hundreds of others is allowed, then I summon Garmuk and all others of good faith to fight at our side.  And know this, Sorath.  If you're listening, if I do not see you fighting by our side now, I will kill you myself, in this life or the next."

Dm: the arena is a 150' ring. But it's about to change so much bigger soon. 

With a quick glance passive Perception. You see mist of these guys are rank and file. A few casters in the mix but quite a few have bows which could be a problem.

Sorath: Summon me with more then empty words and I'll help love, other wise don't die and you'll get your chance to kill me tomorrow.

The Syndicate leader( SL) starts to laugh. Ha ha ha. No no that's not how this works. You can't simply ask for help. Fools... (evil mono log) I have this here amulet that let's me summon all who pledge themselves to me, ready for battle muhahaha. Kill them

 The first wave of rank and file runs in.

Order: Stage, Aino, Casey, Syndicate member (SM) 1, 2, 3, 4 ,5, 6, Kileprat, SM 7, 8, 9, 10, SL (too far to attack) 

At the top of the order the stage expansion to make room for all the new fighters. It now looks like an open battle feild with ruin walls around. The Syndicate Leader now is 1000' away ish with an army between you. You can see his 3 LTs each commanding a section of the army.

Aino is up.

OOC:  If those are the rules, those are the rules.  But I heard the ONLY rule is "anything goes as long as you don't leave the arena."  Is the Syndicate Leader making up new rules when they say there's no asking for help?  Because I never heard that we couldn't get help when the rules were stated.

Also, I see Kileprat in the Initiative.  Is she fighting at our side?  Or on the side of the Syndicate?

(Yes- my pre-buffs are up above somewhere.  Inspiring leader for 18 HP each (even the owl).  And aid for 15 bonus each).

watching the scene in shock… Casey turns to aino-.  “Do we have a way to teleport or dimension door over to the leader?” Casey thinks (we have telepathic bond up) 

"I have Dimension Door but that is only 500'.  I can take one person with me.  I suppose I could cast it twice."

Also note:  we have Rary's Telepathic Bond between us active.  So all intra-party communication is telepathic and not audible to others.

Casey replies mentally- “we need to get that amulet, methinks..”. 

DM: 2 things, 1 remember Earth could not go any farther then the walls surrounding the sands, 2 Casey is a rock star now, she might have groupies...
