Rethan charges into the room, staff spinning in stunning flurry of attacks that the eye can barely track.  As the last attack lands he releases the staff with one hand and unhooks the shield from his pack, holding it between himself and the foes.

Attack: 25 Damage: 8
Extra Attack: 26 Damage: 11
Bonus Attack (Polearm master): 17 Damage: 11

Action Surge

Attack: 20 Damage: 7
Extra Attack: 11 Damage: 9

(So move into melee, attack, bonus attack from polearm master, action surge to attack again, then after all that, use my 1 free item interaction to equip my shield so I have the extra 2 AC for defense.  Prioritizing goblins with the attacks unless I have to move past bugbears and give up attacks of opportunity to do so)

Rethan rounds the corner and comes face-to-face with a goblin and a bugbear. He dispatches the goblin with a single blow. The next three attacks strike the bugbear before it falls. He slides forward a few more feet and jabs at the next goblin, splitting open its head with a single strike.

Laniel charges forward over the fallen bodies that Rethan left in his wake. He strikes at the next bugbear with his quarterstaff twice, followed by two rapid front kicks (bonus attack; spending 1 ki). If the bugbear is still alive, it gets no reaction. If it dies before the final strike, Laniel moves on to a goblin.

Quarterstaff Attack: 23 Damage: 6

Quarterstaff Attack: 22 Damage: 6

Kick Attack: 24 Damage: 6

Kick Attack: 17 Damage: 5

Laniel tangles with the bugbear but it doesn't fall. He does manage to keep it distracted enough that it can't react when he slides back to where he was before.

Titus is up.

Sliding in after Rethan's flurry of blades, Atuan's nimble rapier strikes towards the wounded bugbear!

Attack: 24, Damage: 11 + Sneak attack: 7

Titus takes a few big steps into the room, and marches for the nearest foe. 

He slams down his foot and plants a firm stance as he winds up his shield to saw at his enemy. Then brings his axe across, and back again, hoping to land two heavy blows.

Athletics 16

Battleaxe 

Attack: 10 

Damage: 10

Attack: 19 

Damage: 6

As soon as he brings his ax back to his side he immediately reverts his shield so its facing directly in front, ready to absorb blows aimed at Titus and his companions.

(Sorry, Atuan was up next. I will apply Titus' attack after the goblins go.)

Atuan's rapier pierces the hobgoblin's chest and it falls dead at his feet.

Two goblins attack Atuan with scimitars:

Scimitar Attack: 18 Damage: 8

Scimitar Attack: 21 Damage: 7

Two more attack Rethan:

Scimitar Attack: 23 Damage: 8

Scimitar Attack: 8 Damage: 5

And two sneak through the door to the north and come up behind Titus:

Scimitar Attack: 10 Damage: 3

Scimitar Attack: 14 Damage: 4

Three goblins fire their bows at Laniel:

Shortbow Attack: 23 Damage: 6

Shortbow Attack: 16 Damage: 4

Shortbow Attack: 5 Damage: 7

Three fire at Rethan:

Shortbow Attack: 9 Damage: 7

Shortbow Attack: 11 Damage: 3

Shortbow Attack: 17 Damage: 6

Two goblins fire at Atuan:

Shortbow Attack: 21 Damage: 5

Shortbow Attack: 18 Damage: 7

And a bugbear throws its javelin at Atuan as well:

Javelin Attack: 12 Damage: 5

And the other throws its javelin at Rethan:

Javelin Attack: 17 Damage: 7

Titus strikes down both of the goblins that came behind him and then moves into the room through the doors *the only way he can get to the room this round.)

Morph is up!

Morph's eyes go wide at the number of goblins that are visible in the room and at the couple that come around to attack from behind.

Morph turns to the bear, giving it a command to enter the fray and attack the goblins.

"Bear, get in there and attack all of the goblins!"

The bear charges in squeezing past his allies, to attack the goblins.

Morph takes aim from the doorway, again letting a pair of magical beams strike out at two goblins in the room.

Morph Bonus Action: Command the bear to attack the goblins (both types)

Bear Move: Charge into the room and get into range of at least two goblins

Bear Action: Multiattack (split between multiple targets if available)

Morph Action: Cast Eldritch Blast (split between multiple targets if available)

Beam 1: Attack: 19 - Damage: 4 force damage.

Beam 2: Attack: 12 - Damage: 6 force damage.

Bear runs in behind Titus and bites and slashes at a goblin. It is too quick, though, and suffers only a scratch on its leather armor.

Morph has better luck, darting behind Laniel to get two good shots off.The first one is frail and is knocked down with a crunch, instantly dead. The second one absorbs the blow, but is left looking very much the worse for it.

Laniel charges back in, his quarterstaff swinging to try and remove as many goblins from the fray as he can.

Quarterstaff Attack: 23 Damage: 10

Quarterstaff Attack: 14 Damage: 11

Kick Attack: 17 Damage: 8

Spinning Kick Attack (for one Ki): 9 Damage: 7

Laniel fells three goblins with his staff and a kick, his flashy final kick sailing over the head of a ducking goblin.

(Atuan and Rethan are up.)

Rethan hooks his shield back onto his pack and his staff begins to flash around him in a blur again as he pushes his way further into the room, striking at foes as he goes.

(Move as far into the room as I can without giving up any attacks of opportunity.  Attack goblins first, Bugbear if I can't reach any goblins without giving up AoO)

Attack: 16 Damage: 13
Extra Attack: 26 Damage: 14
Bonus Attack (Polearm master): 16 Damage: 14

Atuan grimaces as the goblin blade and javelin strike home, unable to dodge out of the way. Pushing past the pain, Atuan recenters his rapier and attacks. Lunging in after Rethan's brutal foray, targeting the bugbear, Atuan strikes again!

Attack: 22, damage: 9 + 8

Rethan smashes his way through three goblins, ending up between Laniel and Titus, facing the rest of the goblins that are now cornered in the room. Atuan slides past Laniel and sinks his rapier into the bugbear, severely wounding it but not bring it down.

The bugbear swings at Atuan with his morningstar to return the favor

Morningstar Attack: 18 Damage: 12

The other remaining bugbear charges in at Titus, doing the same.

Morningstar Attack: 8 Damage: 6

Two goblins swing their scimitars at bear.

Scimitar Attack: 13 Damage: 4

Scimitar Attack: 6 Damage: 6

One more swings its sword at Rethan:.

Scimitar Attack: 7 Damage: 8

And one at Laniel.

Scimitar Attack: 20 Damage: 8

With the final one striking at Atuan.

Scimitar Attack: 23 Damage: 3

Laniel takes cut from the dull blade while Atuan is struck by the bugbear's morningstar and a goblin's scimitar. Bear takes a hit from a scimitar as well.

Morph and Titus are up.

The bear roars in pain and strikes back at the two goblins.

Morph moves up behind Rethan and Laniel and takes aim at different pair of goblins with his rod, letting twin beams lance out.

Bear Action: Multiattack

Bite Attack at 1st goblin: Attack: 22 - Damage: 5 piercing damage.

Claw Attack at 2nd goblin: Attack: 25 - Damage: 14 slashing damage.

Morph Action: Cast Eldritch Blast

Beam 2 at 2nd goblin: Attack: 9 - Damage: 10 force damage.

Bear injures one and strikes down the other while Morph manages to strike one of his own, missing the other completely.

Titus is up!

Titus turns to the nearest bugbear, and places his shoulder behind his shield, using his weight to shove the creature to the ground. He bears down upon him with two vicious swings. He then regains his footing and naps his shield back up to protect his comrades on either side of him. (Titus is ready to use his reaction to impose disadvantage on an attack made against Rethan or the bear.)

Athletics 11

Battleaxe Attack 1: 17 Damage: 12

Battleaxe (If target is prone): 15

Battleaxe Attack 2: 26 Damage: 11

Battleaxe (If target is prone): 18

Bugbear STR(11) check: 13

The bugbear stays standing but Titus' axe still lands both times. It wobbles slightly as blood pours out of its wounds but it stays standing.

Laniel strikes at the goblin next to Atuan and, once it is down, goes after the bugbear next to him.

Quarterstaff Attack: 19 Damage: 13

Quarterstaff Attack: 14 Damage: 12

Elbow strike Attack: 11 Damage: 6
