(How far is storm from the giants now? Can he reach them with a normal movement?)

BB lets out a whoop, hoping no one saw him miss a target literally the size of a barn.

((Perfect))

Bryn quickly moves to one of the giants and with a flourish, sneaks in a stab at it with his rapier while it is looking down at Ayen’s attack. He then (bonus action) Misty Step 30 feet northwest and shouts “Ha ha!”

Attack: 18 Damage: 12

Sneak attack: 11

Wild Surge chance: 12

((It'd be a Dash for Storm to get there, unless you've some other battlefield movement options.))

Bryn darts in, slashes and pops back away.

Storm casts misty step as he moves towards the giants with his normal stride as well.

Surge: 29

He then strikes at the giant... Calling on Tides again as he does so.
Attack: 24 Damage: 13

Storm's mind and fingers feel swift and nimble as he comes out of his step as he carves into the sunburned giant!

((You already had advantage from them being prone if you want to save Tides, but if you just wanted to prime it for chaos, that's fine too!))

 ((That's also *just* enough to finish it, so if you want to put some flavor on it, go for it!))

Storm strides towards the fallen giants, gritting his teeth as his weapon's anger roils through him. Unable to reach them though he disappears in a puff of mist, then reappears standing atop one of the giant's chests. Staring down into the surprised giant's eyes, he gives the dumb brute a grim smile, before driving his sword down into the thick chest under his feet. he gives the blade a brutal twist, feeling the flood of life blood spilling forth as the heart stops to beat.

Rusty will mutter to himself, then shrug and toss out another chaos bolt/spectral hammer combination on whatever giant is still standing.

Using Tides for the Chaos bolt:

Chaos: 14 Damage: 14

Spiritual: 11 Damage: 10

Surge: 29

Rolled the wrong dice for chaos bolt damage: 14 fire damage

Storm finishes off the sunburned giant efficiently, while Rusty adds acid to acid and CB's the remaining giant. His hammer floats serenely towards the giant, but isn't able to reach this turn.

There is a creak and scream of metal as Rusty grows to match Bolt in size.

 The acid that Grandpa splashed on the giant has been going to work, sizzling as it burns in, dealing 14 acid damage.

 ((Grandpa, that's sufficient to hill him if you'd care to get more graphic than he dies due to acid...))

((We'll stay on turn order, as Bolt is still going off, some of you have saves to possibly make, and more giants may show up, but you've a bit of a breather perhaps as the three giants that attacked you have been dispatched! With barely a scratch to the party (thanks to Ayen being able to soak 24 damage before it touched his real HP!).))

Randy moves up to BB, giving him a stoic nod.

(Did Patter get free of the laughter with a 14 WIS save?)

((Ah, yes. Looks like DC was 13.))

When grandpa shoots the stream of acid from his wand, he hits the giant in his face where it starts to burn into his flesh. The giant scratches at his head, but it's to late and after a view moments he falls down, dead. 

"Is that it? They're all dead?" Verne asks cautiously. "Is everyone ok?" He looks up at the huge figures to his side. "You guys are really big." He chuckles lightly at the large pair. His thoughts turn to Ayen. He'd taken a big hit. Verne looks for him on the battlefield. 

Rusty looks down at himself in faint puzzlement, then slowly nods.

"Yes.  It would seem I am indeed abnormally large."

“I doubt if that was the lot of them.” Storm says, getting his men to stay on their guard.  He tugs his greatsword out of the one giant’s chest, then cleans it off on the same giant’s hides.  Looking around he nods to Red.  “Can you get him up and see if any other giants are in the area?”

Keller finally stops laughing and looks around, seeing dead giants. "What did I miss? Any more?"

He readies a crossbow bolt in case any other giants appear.

Bolt still rolls around on the floor, laughing. Still a large half-elf. Still naked.... Just unbelievable. And in this state, who could possibly keep their magic under control?! The wild magic surges come in hard and fast.

Roll wild magic: 70 [cast bestow curse] Roll to end laughing: 9
Roll wild magic: 88 [???]  Roll to end laughing: 14 and finally she is able to control the laughing and stand up. It is clear to her, that in her current condition she better retreats to safety and stays out of the range of her company. She dashes West to make sure no one gets hurt from her magic surges. 
Roll wild magic: 26 [Suddenly, Bolt's eyes grow over with skin, and she is blinded, but her ears enlarge and she has blindsight to a distance of 30 ft.]
Roll wild magic: 10 [Select a random creature within 30 feet of you. Roll again on the Wild Surge table, for the purposes of this additional role's effects, the target creature is considered the 'caster'.] - rolling perception below to find an animal - hopefully I am far enough from my friends
Roll wild magic: 94 [???]
Roll wild magic: 18 [You change to a random humanoid race, but slowly revert over 2d12 days. Your stats and abilities are unaffected. A remove curse spell can end this effect.] rolling to revert below
Roll wild magic: 98 [You are surrounded by an odor that can range in strength (1d4) and and from nauseating to enjoyable (1d10). This odor lasts for 1d6 hours.] A very strong smell is coming off Bolt for the next three hours - it's a mixture of mud and some horse poo that she rolled in while laughing. 
Roll wild magic: 35 [???]

Bolt just lets all the extra magic out. She is used to this now, she has seen it many times in her friends. But for her, it was the first time to lose control like that. Stupid laughing spell. She swears to never lose control like that again. 
            
perception: 11 - wild surge roll 49 [You can't speak for the next minute. Whenever you try, pink bubbles float out of your mouth.]
how many days humanoid: 7
odor rolls: strength 4 and quality 3 and how long 3

Verne is able to spot Ayen, and moves to help.

Bolt curses herself... 2 ... and is reluctant to hit herself.

One of her handaxes grows arms and legs and hops out of her pack.

 It slaps its little hands against it blade head, and tries to chop her!

Attack: 18 Damage: 5

((Since the save is at end of turn, you're still prone! Anyone else who wants to do things while Bolt is surging, can do so before I process the rest.))

grandpa walks up to Red and tries to shake it awake (not sure how many rounds left for the laughter; so this should be enough saves to know when he is shaken enough to come back to us)

Well apparently Grandpa's shake is amazingly good and Red gets back right away. After a short check up to make sure he is alright Grandpa tells red to fly up and scout ahead a bit and come back with a count of the giants in close proximity (lets say 500ft)
