The Tales of the Fellowship of the White Cloaks

"No point on trying to focus on the weather now!" Rhogar said with a touch of manic excitement to his voice. Gorrah chirrups in agreement as the dragonborn went on to further empower his fellows with a bit of divine. That, or had wisdom prevailed earlier with him having completed all preparations prior, he'd put his new staff to work conjuring a great conflagration for the giant boys to deal with. In either case, and as much as it wounded his pride, he'd then hunker down further behind Mythallar to wait until their foes were more within ranger of his spells.

Meanwhile, Gorrah snatched up a treat from Rhogar's pocket, before then taking to the air and flying in a defensive pattern for the time being.

Action(Rhogar): Cast at (3rd level)Exuberance on Rhogar, Gorrah, & Oli. 
(S/N: This is also to make it official that Gorrah has 17 HP, as the benefit was always from level 3 aid usual done as part of daily prep as shown in spoiler. But, since I failed to post a reminder, and circumstances being what they were, the usual prep should probably be ignored. Otherwise, his alternative Action would be to cast Bless on himself, Kazri, and Oli.). 

 Bonus Action(Gorrah): Eat Treat, gaining 4 Temp Hp.

Action(Gorrah): Defensive Maneuvering. 

Movement(Rhogar): Hunker Down. 

(I'm good with the spoiler action as you said previously it was something you did all of the time so I'm going with you did it.)

The frost giant bellows in rage as it sees Krom move towards it and he rushes forward and closes the distance between them

Kazri is up

Initiative: Krom (94/94), Chill (63/63)+10, Auril, Rhogar (77/77)+4 Bless & Gorrah (17/17), Frost2, Kazri (104/104)+10 Bless & Oli (42/42) Bless, Frost1

"Oli, stay and guard Uncle Rhogar." Kazri commands Oli, and he will move just south of Rhogar.

Kazri runs towards the nearest Front Giant. (I believe Kazri is too far. She will just dash to Frost Giant 2.) On the way, she curses herself for being in the wrong position. She blames herself, that she should have known where the enemy would come from.

While Rhogar take a defensive position Kazri moves runs forward to stand shoulder to shoulder with Krom.

The other frost giant, seeing Chill fire his crossbow at Auril dashes forward and closes the distance between he an Chill

Krom is up followed by Chill

Initiative: Krom (94/94), Chill (63/63)+10, Auril, Rhogar (77/77)+4 Bless & Gorrah (17/17), Frost2, Kazri (104/104)+10 Bless & Oli (42/42) Bless, Frost1

Chill reacts to the huge frost giant running up to him and getting within melee distance of him.  He then bounds out of the way moving northwest 20 feet along the north edge of the rock he is by.

(Reaction - Skirmisher: I should be able to move north 2 squares and then NW 2 squares diagonally.)

“This giant is in the way, I can’t get a clear strike at Auril!” Krom shouts as the frost giant lumbers toward him. “Let’s bring him down first, lass!"
With a roar, the dwarf swings his flaming warhammer in a powerful upward strike, aiming for the giant’s leg.
As he attacks, Krom chants a hymn of evocation, conjuring a translucent maul that immediately mirrors his blow, crashing into the towering foe.

Action: Warhammer attack on Frost Giant 2 - Attack: 11 Damage: 13 + 3 Fire Damage

Bonus action: Spiritual weapon at 2nd level. - Attack: 23 Damage: 7

The frost giant bats Krom' strike with his warhammer aside but does get struck by the spiritual weapon.

Meanwhile Chill is beating feet trying to stay clear of the frost giant that has moved his way.

Chill is up

Chill knows he can't go toe to toe with a frost giant like Krom or Kazri can.  He needs to get away.  He continues to move around the rock counter clockwise to get out of sight of the giant who is very tall.  He looks up at the rock he moved around wondering if it is tall enough to get out of the reach of the to giant.

Chill will use feline agility first and then his movement speed to move as needed to get to the opposite side of the rock.  From there he will climb the rock and use his bonus action to hide as best he can if the terrain allows it. He will also take the dodge action if the rock isn't high enough.  If it is high enough he will fire his crossbow at the giant.

Game log: 12 to hit. 12 damage

Chill moves around the rock formation and climbs the far side, his natural climbing ability possibly saving his life.  He finds the formation to be about 30 feet high at its highest spot but there is nowhere to hide.  He is out of the reach of the frost giant who is about 21 feet tall, out of reach for the moment, but his shot from the crossbow goes wide.

Auril teleports 30 feet and then flies over Krom and Kazri and heads towards Rhogar, still 20 feet in the air. She launches a sphere of cold energy at Rhogar who despite laying prone and having partial cover from Oli standing guard over him it hits.  

Game log hit 18, damage 10 (you get 5 as you have resistance)

Rhogar is up

Initiative: Round 2 - Krom (94/94), Chill (63/63)+10, Auril, Rhogar (86/87) Bless -9 & Gorrah (17/17), Frost2, Kazri (104/104)+10 Bless -9 & Oli (42/42) Bless -9, Frost1

(Conc. Save auto-pass thanks to bless and +9 natural Con)

Reaction(Rhogar): Cast (1st level)Righteous Retribution on Auril. Dex Save(DC 16) to take half of 6 Fire damage.

Following a grunt of pain, Rhogar glared at the ice maiden with eyes dimly alight with divine fire. The same which would appear as a mote just beside the owl hybrid form of the goddess before rapidly expanding into a localized explosion of heat. Afterwards, the dragonbornl found his footing once more, and brandished his staff at Auril. "Sorry to disappoint you, wretched goddess, but I am no foe that shall so easily succumb to your wrath!" He declares, before directing the staff towards the giant engaged with Kazri and Krom. "Egnotom!" He commands, conjuring a bead of green flames at the tip and sending it flying at a high arc with but a wave of the staff.

Action(Rhogar): Cast from Staff (3rd level)Fireball on Giant(#2) space. Dex Save(DC 16) to take half of 32 Fire damage.

Action(Gorrah): Continue flying defensively. 
(He's aiming it in such away so that it only hits the giant and noone else)

Future Reaction(Rhogar): If targeted by an attack, he will cast (1st level)Righteous Retribution.
If he sees her cast a spell instead before the previous trigger, he will try (3rd level)Unravel it.
If none of the above happens but Gorrah is targeted for an attack, he will use his Pact of the Chair to halve the damage.

Auril Dex save 23

FG Dex save 14

The frost giant ignores Kazri as she runs up, his hatred for dwarves drives him to attack the one that stands before him but Krom is too agile for him and both strikes with its great axe miss.  (to hit 20 & 19)

Kazri is up

"Master Krom. I will get the attention of the other one, so that Chill can do what he does best."

Kazri dashes to FG1. (She will take the AOO)

"Hey!! Over here! Fight me!" Kazri screams at FG1.

The frost giant takes the opportunity and swipes at Kazri with its axe. (26 to hit, 20 damage ... -3 for feat, 17 total)

He gets a solid hit on her back as she rushes away. (I'll hold off on applying damage as I'm sure Krom will use his reaction to reduce that)

The other frost giant hears Kazri as she rushes up and turns to defend itself and swings its axe at her. (25 to hit, 22 damage, 23 to hit 19 damage ... -3 on each hit, 35 total)

Krom is up followed by Chill

Initiative: Round 3 - Krom (94/94), Chill (63/63)+10, Auril, Rhogar (86/87) Bless -8 & Gorrah (17/17), Frost2, Kazri (74/104) Bless -8 & Oli (42/42) Bless -8, Frost1

“All right, lassie, I’ll take care of this one!” Krom shouts as the paladin dashes toward the other giant and Chill. The dwarf slams his shield into the giant’s leg just as the creature swings its axe toward Kazri’s back, disrupting the blow.
“Now it’s just you and me, longshanks,” Krom growls, tapping his shield with his flaming hammer. Chanting a hymn of evocation, the dwarf brings his hammer crashing down onto the icy ground before him. Fiery cracks spread outward like a spiderweb, racing behind the frost giant as the ice hisses and melts. In an instant, a towering wall of fire, twenty feet high, erupts, hemming the creature in blazing heat.
At the same time, an unseen force drives the translucent maul forward, smashing into the giant’s torso with crushing force.

Reaction: (from my previous turn): Interception on the attack against Kazri - Damaged reduced by 13

Action: Wall of Fire - 60ft long 20ft high placed behind the Frost giant as indicated in the map below. 23 Fire damage - Dex Save DC 15 

Bonus action: Spiritual weapon Attack: 17 Damage: 5

OCC: @DM Wall of Fire added on the map as follow

(Kazri damage from the AOO is reduced to 5, sheet updated)

As the wall of flame erupts the frost giant instinctively moves and saves itself from the worst of the flames (Dex save 19).  However, distracted by the wall of fire Krom's spiritual hammer slams into into it.

Chill is up

Those frost giants rolled really well this round

Chill watched as Kazri broke off from the frost giant she and Krom were battling to come help him.  He was going to waive her off but it was too late. He had hoped to keep this one busy while Kazri and Krom teamed up to take the other down quickly.  Krom's on his own now.  Now it's Kazri and Chill teaming up to take this brute down.

Up on his perch Chill takes steady aim at the Frost Giant and fires 

27 to hit,  38 damage from Game log

A solid hit by Chill and the Frost giant bellows in pain.

Auril hovers where she is, 20 feet in the air.  Rhogar, seeing she is casting a spell reacts quickly to unravel the spell and Auril's spell fails. (Rolled throw in Game Log)

Rhogar is up

Initiative: Round 3 - Krom (94/94), Chill (63/63)+10, Auril, Rhogar (86/87) Bless -8 & Gorrah (17/17), Frost2, Kazri (74/104) Bless -8 & Oli (42/42) Bless -8, Frost1

(OOC: So, I'm realizing in hindsight that when I cast the fireball before from the staff, the base level of that is 5th level, not 3rd. So, I short changed myself some dice. Since it also lightning bolt built in for the same price as well, gonna assume Rhogar did that instead to make things simple.)

"I may be no true master of the arcane, but you'll have to try harder than /that/ if you wish to turn the Weave against me!" Rhogar dared to call out as whisp of magical electricity dissipated harmless into the air following his swift dismantling of the frost maiden's magic. But, as much as he would've liked nothing more than to redirect his efforts towards putting down the maiden, if not at least dissuading her from attacking him, more power is instead drawn from the staff in hand to deliver a potent fireball sailing directly for the giant yet engaged with Krom.

Action(Rhogar): Cast from staff (5th level)Fireball, positioned to only include Giant(#2). Dex Save(DC 16) to take half of 41.
(Rolled in Gamelog)

Action(Gorrah): Continue Defensive Maneuvering.

Future Reaction(Rhogar): If he's hit by an attack from Auril, he will cast (1st level)Righteous Retribution.
If he sees her cast a spell instead before the previous trigger, he will try (3rd level)Unravel it.
If none of the above happens but Gorrah is targeted for an attack, he will use his Pact of the Chair to halve the damage.

Another explosion of flame engulfs the frost giant that Krom fights (dex save was 8) and it is burned again.

The frost giant continues its relentless attacks against Krom (25 to hit, 27 (-3 for feat) so 24 damage, 16 to hit - miss) and gets one solid hit on Krom. (damage noted on sheet)

Kazri and Oli are up
