Ok going to roll counter persuasion. 

Roll 18

Ok I'll give you a +2 for the price 

5

You get 1250 gold

Ok! 

Aino sells her Arcane Grimoire, +2 (bought for 2k gp, selling for 1k gp) and her Studded Leather, +1 (bought for 400gp, selling for 200gp).  She won't need either of them any more because she is buying something that does the job of both and better.

For 10k gp, Aino buys her legendary item:  a dark gray Robe of the Archmagi.

AC 2 better than the Studded Leather, +1.  Gives her the same +2 to Spell DC and Spell Attack Roll that the  Arcane Grimoire, +2 did.  But also advantage on all saving throws against all spells and other magical effects.  All in one item.  Figured that was the best choice.

Also just wanted to clarify what an amazing job Casey's combination of 5th level Aid and 15 Temp HP from Inspiring Leader is.  Temp HP doesn't stack with itself, but fortunately, Aid doesn't give Temp HP, it increases Max and Actual HP, in this case by 20, and we get the 15 Temp HP on top.  Thanks Casey!

(Thanks!  I knew they stacked, wish I could give aid to all of us, but it limits to 3.   Figured Storm may need more than Kileprat!   Cool I can give 15 HP to your owl. Familiars are so vulnerable in 5e!) 

OOC: Storm is ready for the next fight, he will cast Bless right as it starts at 2nd level to include himself, sorry no owl.

(OOC:  Aino casts spells to prep too but no time to write it out yet - hopefully in a few hours.  And definitely don't waste Bless on the owl!  The Temp HP for the Owl from Casey, since Inspiring Leader goes up to 6 targets, is great though!)

Aino's combat 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.  Lasts 1 hour.
• Casts Fire Shield (choosing cold shield, granting fire resistance) - takes 1 Action, lasts 10 minutes, no concentration.
• Just before battle, Aino starts her bladesong with a bonus action and casts and concentrates on Bigby's Hand (both last 1 minute, so 10 rounds).

Aino proposes the Phantom Steed idea to Storm and Kileprat.

"Does one of you want a mount with a 100' move speed for the combat?"

"I have never been much for riding, but last fight I did have issues getting to our enemies so I will try it."

(Casey also casts Telekinesis - (magical secrets) right before the fight. ). 

The party wakes feeling refreshed and ready to go. As you head down stairs Sorath is waiting.

"Good morning. Hope you slept well after yesterday's exciting.... events." 

As you head to the arena, the crowd has tripled. You hear cheers and praise and a few boos. Mist are happy about the message you sent to the Syndicate. Rounding the corner on the road that leads direct to the Arena you see Aino's handy work on display. With a message written in blood.

Dear Syndicate.

$%^# you! Leave the town out of this. Meet us in the Finals.

With love.

The Last Copper.

P.S. Garmuk says HI 

Sorath "Hope you don't mind my little display with your handy work"

The party moves past the display and into the arena. After an hour of prep the portal opens to the fight

The party steps onto a long narrow bridge. The bridge is 30 feet wide and 200 feet long. Looking over the edge you don't see a bottom. Before the party is a blank wall, 30 feet wide 30 feet tall 

You hear Dan's voice.

Welcome all to the challenge round against the demon wall. Only 2 teams left, this will be the first look at what the final might hold. 

The wall in front of the party starts to come alive. A head torso and arms grows from the wall 

Everyone rolls initiative 

Casey 12. 

Aino Initiative (at advantage due to Shortsword of Warning):  21

Initiative: 10

Kileprat hasn't been around for a few days so I'm going to roll Initiative for her.

Kileprat: 18

Order: Aino, Kileprat, Casey, Storm, Wall

Aino is up

Sorry, a question before Aino's turn:

What size is the creature (demon?) emerging from the wall.  Large?  Huge?  Asking because Aino's Bigby's Hand which she is concentrating on has a few options for her bonus action, one of them being a grapple (Grasping Hand), which is limited to huge or smaller opponents.

Note 1:  Bigby's Hand has 102hp, STR 26, DEX 10, AC 20, is Large-sized but doesn't occupy its space unless blocking movement with Interposing Hand.

Note 2:  The PCs can all breathe underwater (for the next 23 hours) and communicate telepathically with each other (for the next 40 minutes), even the owl, thanks to Water Breathing and Rary's Telepathic Bond respectively.  Not that it should matter that much, but just in case...

The demon is the wall so 30x30 which is huge I believe. If you use this spell you won't be able to stop the wall from moving forward but I'll allow all other effects grapple provides.

What about dragging the demon/wall off the path laterally and dropping it into the void as you could normally do with a flying grappler (Bigby's Hand) that can move 60' on a turn?  That was my main idea, though the Grasping Hand can also deal some automatic damage once it grapples.

Basically - this affects my choice on whether to use Bigby's Hand for Grasping Hand or Clenched Fist as a bonus action.  I'll post the rest of Aino's turn now and wait on your answer to decide her bonus action.
