Morph stand behind his friends, weary of the goblins and Halleth, but not willing to attack, until provoked.

It would seem, not everything in Undermountain conforms to expectation.

Action: Ready Action

Trigger: The first to take hostile action against Morph or his friends

Action: Cast Eldritch Blast at target:

Beam 1: Attack: 24 Damage: 1 force damage.

Beam 2: Attack: 17 Damage: 6 force damage.

Concentration: Readied Eldritch Blast

I forgot to put Halleth on this map. He is right in front or bear.

Four goblin groups:

Goblin A
Goblin B
Goblin C
Goblin D

(And are squares 5'?)

(10' x 10' but I did't want to zoom on the map any further than I did!)

Rethan also doesn't want to be the one to kick off a fight, so instead he takes a step forward (to be just inside the nearest 10' choke point) and gets ready to dodge any incoming attacks.

Dodge action.  And with polearm master I can potentially use my reaction to attack a goblin that enters my reach if I want.

To save time, I'll use said reaction to attack the first goblin that enters my reach *after* any goblins have attacked any of the party members.  So if the first one walks up and attacks me, no reaction on that one, but if a second approaches me I'll take the AoO on him.  Or if one of the others is attacked first, then another approaches me.

AoO if needed: Attack: 16 Damage: 8

Titus positions himself in the hallway so there are three of the Goblin B group in front of him.

”STAND DOWN!” He bellows “We have no quarrel with you, but we must proceed through these tunnels. I’ve a piece of silver for each of you if you let us pass... and a piece of steel if you don’t!” He waves his battle mace menacingly at the horde.

Intimidation: 19

Do any of the Goblins appear to be a leader?

The chaos is so loud and disorganized that only a single goblin responds to Titus by fleeing across the room. Nobody is in charge here. Halleth is momentarily stunned, but he looks like he is about to leap into the fray.

Halleth looks across the room filled with rioting goblins and a madness fills his eyes. He roars an unearthly roar and every goblin stops in its tracks and turns to look at Halleth and the adventurers. One of them yells in goblin:

 and then the goblins scramble for the nearest weapon they can find.

(Initiative rolls made previously still apply. Adventurers are up first in any order.)

With a quickly chanted prayer, a shadow copy of Atuan seems to step out his billowing cloak! The two seem to cross paths for a moment, and now who can tell which is which! (Atuan being body-blocked by his copy). The copied figure runs to the side, hugging a wall and making threatening gestures with two illusory knives.

Morph walks closer to the bear so he can see more clearly around the corner.

"Looks like this is going to go like our last interactions with goblins, isn't it?"

Morph lets out a sigh.

"Well Bear, get stuck in."

Morph waves his rod in the direction of the goblins, seeming to be gesturing for the bear, but with an arcane word, twin beams shoot out of the end of the rod.

The bear lumbers forward to engage the goblins in front of him.

Morph Move: 10ft North to stand behind the bear

Morph Bonus Action: Command the bear to attack the goblins

Morph Action: Cast Eldritch Blast

Beam 1: Targeting the goblin directly to Morph's East: Attack: 13 - Damage: 2 force damage.

Beam 2: Targeting the goblin North of the first target: Attack: 9 - Damage: 1 force damage.

Bear Move: 10-15ft East, to get within melee range of the first goblin Morph targeted and the goblin south of that one.

Bear Action: Multiattack

Bite: Targeting the goblin that Morph attacked first: Attack: 18 - Damage: 6 piercing damage.

Claws: Targeting the goblin south of the bear's first target: Attack: 13 - Damage: 11 slashing damage.

Morph's two attacks fire low and wide, respectively. Bear, meanwhile, runs forward and bites at one of the goblins, tearing a chunk of flesh from the surprised enemy. It moves quickly to dodge the bear's deadly claws, however.

Laniel, seeing the way things are going, charges in as well, striking four times (using Ki) at as many different goblins as he can, using his staff, elbows, and feet.

Quarterstaff (two-handed) Attack: 26 Damage: 10

Quarterstaff (two-handed) Attack: 26 Damage: 7

Elbow Attack: 8 Damage: 6

Kick Attack: 23 Damage: 10

Only one strike of Laniel's lands, felling the goblin that Bear bit.

(Rethan and Titus are up. Also, look, a better map! The X is Halleth, who goes after the goblins. Unfilled diamonds are dead goblins.)

Titus sighs as the chaos unfolds before him. He moves first to the north and then east to attack the purple diamond goblin. He opens with a vicious shield bash, and then two blows from his battle axe.

skill]Athletics[/skill] 17

Battleaxe Attack 1: 19 Damage: 6

Battleaxe (If target is prone): 26

Battleaxe Attack 2: 25 Damage: 7

Battleaxe (If target is prone): 19

As strong as the goblin might be among his peers, he is no match for Titus as the dragonborn knocks his foe tot he ground. But his enemy is quick and the first blow is narrowly dodged. The second comes too quickly, though, breaking a rib on the goblin with a crack. It still lives, however.

Rethan is up!

(Back from the holidays!)

Rethan moves past Halleth into the room and starts lashing out at goblins.

(Move to the square just south of the green diamond, to have the green and blue both in range.  Target the blue one first, if it dies, target the green for remaining attacks)

Attack: 25 Damage: 9

Extra Attack: 23 Damage: 8

Bonus Attack: 12 Damage: 9 

Rethan charges in past Atuan (or his duplicate) and begins to efficiently chop down goblins. In fact, three goblins fall to his strikes in rapid succession.

Finally, Halleth punches GP3 and GB3 so hard and so fast their bones crunch. His eyes go wide and he looks at his bloodied hands. A maniacal cackle escapes his lips.

(Everyone may go in any order.)
