Aranea hits the Orc with an eldritch blast just as Barkpanther shoves him off the top of the tower.  Whether it was the energy bolt or gravity that ultimately does him in, you don't have time to consider. 

The Orcs cry has roused the camp.  Within the walls there is the grunting and shouting of Orcs, as those who were awake rouse the rest from slumber.  Also, you hear the deeper, louder groans and rumbles of the Ogres, stirring from their rest, pushing their weighty bulks up off the ground, and grabbing their clubs.

Orcs: 8

Ogres: 11

New Initiative Order:  

1. Aranea
2. Droknin
3. Orcs
4. Ogres
5. T'laren/Neral't
6. Barkpanther

(Alright folks. Are we keeping this fight inside, or bringing it outside? I am thinking, if we keeping it inside, we stay in this quadrant. Droknin can jump down and block the entrance to the tower, you guys take folks out with range artillery.)

((How high are the walls? T'laren may be able to use Neral't to get into position to provide cover both inside and out.))

20 ft.

((That should be doable, since Neral't is a magical object that is movable be T'laren, and need not follow movement constraints of a creature.))

Deciding that height will give her an advantage, Aranea's form shimmers and dissolves into mist. A moment later you see the black-clad warlock standing next to Barkpanther on top of the tower. She nods to the transformed Barkas. "I can unleash my magic to great effect from up here," she says.

Then she scans the field below her, searching for a suitable target. She decides to attack one of the orcs closest to her tower and unleashes another bolt of dark, crackling energy.

Action: Attack: 16 Damage: 10

Bonus Action: Misty Step

Suddenly finding himself all alone outside, T'laren will move himself and Neral't close to the base of the tower, his echo rising slightly up above him, as he holds an arrow nocked.

((Don't think I can get Neral't up to the top of the watch tower this round, but can get him there next turn and swap places.))

Droknin jumps down from the NE tower, and he stands in front of the entrance to the tower. He takes a deep breath and give a loud growl. Issuing forth a challenge to all the Orks and Ogres in the area.

Athletics: 10

(Droknin will try to hold them off, and you guys take care of them from the top of the tower. And yes, Droknin is insane. You only live life once!!)

Barkpanther can climb down 40 feet / move 50 feet, joining Droknin for a twin big cat attack.  He pounces on the closest Orc, attempting to knock him down with his pounce attack.  

Claws : 20 to hit, for 3 points of slashing damage.  

Pounce. If the panther moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, the panther can make one bite attack against it as a bonus action.

Bite (if applicable) : 17 to hit, for 6 points of piercing damage.

Droknin leaps down, roaring a challenge at the roused Orcs.  For any lesser mortal, the 20' drop would have been a challenge.  Not so for Droknin, as the leonin barbarian does not know about gravity.  From above, Aranea blasts one of the Orcs with eldritch power, though it seems to do little more than bring the warrior's blood up.

In a mass, the Orcs charge the tower.  The nearest four surround Droknin, hacking away at him with their greataxes.

Greataxe Attack on Droknin:  19  Slashing Damage:  10

Greataxe Attack on Droknin:  20  Slashing Damage:  14

Greataxe Attack on Droknin:  24  Slashing Damage:  4

Greataxe Attack on Droknin:  14  (Miss)

[Is Droknin raging?  If so he can burn a reaction to do his tail thing and apply a d8 to his AC against one of those successful attacks.]

From out of the darkness to the west, a trio of javelins fly in.  One of them misses Aranea atop the tower, with the other two target Droknin.  One of them even hits!

Javelin Attack on Aranea (w/disadvantage due to range):  11  (Miss)

Javelin Attack on Droknin (w/disadvantage due to range):  13  (Miss)

Javelin Attack on Droknin (w/disadvantage due to range):  22  Piercing Damage:  7

From the south, another and much larger javelin sails in, embedding itself in the tower doorjam just next to Droknin.  From that direction, three booming voices emerge.  

"What dat?"

"Orcs fightin' sumbuddy."

"Smash 'em up.  I was sleepin'.  Bash 'em up, smash 'em up."

Javelin Attack on Droknin (w/disadvantage due to range):  15  (Miss)

T'laren prepares to ascend the tower next turn, while Barkpanther descends in a flourish, pouncing on one of the Orcs nearest Droknin.  He knocks the Orc to the ground with a snarl, and then bites him again for good measure.  

Orc save:  6

The Party is back up!

[Pinkish Orc is prone.

Also, the black circles around the fires are places that are illuminated.  Everywhere else is dark, for purposes of calculating darkvision range.]

Aranea winces as she sees the orcs converge on Droknin. However, the tabaxi is a mighty warrior, and he manages to endure the onslaught. The warlock is suitably impressed, but she endeavors to help him out however she can. Invoking her dark patron, Aranea curses one of the orcs and follows her hex with another blast of dark force energy.

Action: Attack: 18 Damage: 4

Bonus Action: Hex Attack: 18 Damage: Unable to parse dice roll. disadvantage on STR

((Ignore the second roll above. That was a mistake. Hex should do 2 damage.))

(Of course Droknin raged!! cough cough...)

Droknin transforms into a beast, but unlike the other changes, this time his mouth transforms into a bestial muzzle. Huge sharp tooth comes out from the Leonin's mouth. (The folks on the tower probably cannot see this change, but I will take it is a quite a spectacle for the Orcs in front of him.)

Droknin growls again, and he takes a big bite out of the Orc in front of him.

Bite Attack: 18 Damage: 7

(Damage above totals 35, so I will take a Droknin takes 18 dmg)

T'laren moves Neral't up and over the top of the tower, before exchanging positions with him and moving to Aranea's side and surveying the field. 

From their unseen position, he sights down on the approaching ogres, drawing an arrow on the middle one before loosing it and sending another after it in quick succession.

Longbow Attack: 25 Damage: 12, Elven Accuracy: 27 to hit if it's better 
Longbow Attack: 21 Damage: 10, Elven Accuracy: 13 to hit if it's better 

He'll duck behind the battlements after he does.

((Bonus action and 15 ft of move to swap positions, additional move to get to edge, Action to shoot from darkness to an illuminated target that can't see him for advantage plus Elven Accuracy, Action Surge to attack again, also with double advantage.))

Barkpanther growls and takes advantage of the prone Orc, biting him and standing over him.  He hisses and growls at the other Orcs, blood dripping from his teeth.  

Bite (with adv on prone) : 20 to hit, for 7 points of piercing damage.  

As bolts of energy and arrows rain down from above, and tooth and claw are wielded on the ground, the fierce wave of Orcs all fall or are badly wounded.  Three go down, and only one is left teetering on his feet in front of Droknin.  

This Orc looks down at the bite wound left by the leonin, and raises his own axe with a battlecry.

Greataxe Attack on Droknin:  22  Slashing Damage:  12

From the west, four more Orcs race in, moving aggressively to close the distance between them and Droknin and Barkpanther.  Two close-in on the barbarian, while the other two attack the druid.

Greataxe Attack on Droknin:  14  (Miss)

Greataxe Attack on Droknin:  23  Slashing Damage:  9

Greataxe Attack on Barkpanther:  25  Slashing Damage:  11

Greataxe Attack on Barkpanther:  9  (Miss)

Further west, the sound of even more approaching Orcs can be heard over the clash of axes.  One draws close enough to loose a javelin at Droknin.

Javelin Attack on Droknin:  17  Piercing Damage:  7

From the south, more lumbering steps and voices can be heard, and then a pair of Ogres step into the light.

(Gasp) "Two kitties!  I wants them!"

"No!  You killed the last kitty.  I gets these ones!"

[From further behind...]

"Hey!  What about Gerog?"

[In unison...]

"No!  No kitties left for you!"

The two nearer Ogres dash forward, trying to find a path to Droknin and Barkpanther through all the little Orcs.

A cry of heartbreak roars out from further south, and in a petulant rage the last Ogre hurls a javelin at Droknin. 

"No kitties for Gerog?  No kitties for yous!"

Much larger than those of the Orcs, the javelin just misses and sails through the arch into the base of the tower, splintering.

Ogre Javelin Attack on Droknin:  14  (Miss)

The party is back up!

[Orc with the red dot is badly wounded.]

(Total damage =28, so Droknin takes 14. The big cat is down to 17HP now.)

He smiles at the drew blood on this round. "Ahh, it is good to finally encounter worthy enemies!!" Then he takes another bite on the Orc.

Bite Attack: 14 Damage: 9

(If the bite attack hits, Droknin restores 2HP)

Aranea watches with alarm as a horde of orcs and now the ogres descend upon Droknin and Barkpanther. Droknin is looking pretty bloody. She hopes the leonin can hang in there long enough, but she's worried about these ogres. Can they handle this fight? Perhaps the ogres are not as interested in harming the "kitties" though. The warlock decides to focus her energies on the orcs for now in the hopes that the ogres will refrain from attacking the "kitties." She transfers her Hex to another orc that is still relatively healthy and then wallops it with an Eldritch Blast.

Action: Eldritch Blast Attack: 24 Damage: 2

Bonus Action: Transfer Hex for 5 damage

T'laren calls forth Neral't in the air above him, then has him rocket upward before an arrow zips down, targeting the same ogre that he just put two arrows in.

Attack: 20 Damage: 9 piercing damage, 10 to hit instead if better than initial roll.

((20 ft tower, call Neral't forth 15 ft above and have him move up 30, so shooting down from 65 ft high at an angle should give him a line of attack on the ogre that is outside its darkvision, to confer advantage boosted by Elven Accuracy.))

T'laren remains behind the battlements, under full cover.

Barkpanther is reeling after the greataxe attack, looking severely injured.  There is a shimmering mist, then the dwarven figure of Barkas appears, appearing fresh and healthy.  He smiles and growls at the orcs, saying “Hah!  Gonna put a walloping on you now!”  

Bonus action : Transform from panther back to Barkas

Movement : none

Action : He casts moonbeam due southwest, placed to envelope the maximal number of creatures possible, and if only one is possible, the ogre to the southwest.  The first round it does damage, it does 9 points of radiant damage, DC 13 Con save to take half.
