One Dolgrim engages Clumulk, while the other goes after the Protector Cannon. They attack with their multiple arms/weapons, mumbling to themselves the whole time:

Dolgrim 1 Morninstar against Clumulk Attack: 10 Damage: 5 Piercing

Dolgrim 1 Spear 1 against Clumulk Attack: 7 Damage: 4 Piercing

Dolgrim 1 Spear 2 against Clumulk Attack: 13 Damage: 6 Piercing

Dolgrim 2 Morninstar against Cannon Attack: 19 Damage: 5 Piercing

Dolgrim 2 Spear 1 against Cannon Attack: 11 Damage: 6 Piercing

Dolgrim 2 Spear 2 against Cannon Attack: 20 Damage: 8 Piercing

You all are up. The Dolgrim stand at the bottom of the stairs leading to the shrine and are swinging wildly against Clumulk and the Protector Cannon.

The Protector Cannon takes a licking, but keeps on ticking, and Elero is suddenly very protective of his creation.  He lashes out against Dolgrim two with two dagger attacks:

Magic dagger: 12 plus 4 to hit and 8 damage

Normal dagger: 17 plus 1 to hit and 2 damage

As a bonus action, the Protector Cannon pulses out 9 Temp HP to anyone who needs them.

Mark will roll back and get some space so his crossbow is more effective. Then he shoots at the weakest monster.

Attack: 9 + 3 = 12 

Damage with sneak: 12 + 9 = 21

Elero's second dagger hits, but both of the other attacks miss. Erix get's a Thorn Whip on Dolgrim 2 fighting the Protector Cannon and drags it toward itself. The Dolgrim rushes towards its new target, Erix. While Dolgrim 1 continues to attack Clumulk:

Dolgrim 1 Morningstar against Clumulk Attack: 20 Damage: 5 Piercing

Dolgrim 1 Spear 1 against Clumulk Attack: 10 Damage: 5 Piercing

Dolgrim 1 Spear 2 against Clumulk Attack: 14 Damage: 3 Piercing

Dolgrim 2 Morningstar against Erix Attack: 21 Damage: 6 Piercing

Dolgrim 2 Spear 1 against Erix Attack: 18 Damage: 8 Piercing

Dolgrim 2 Spear 2 against Erix Attack: 21 Damage: 3 Piercing

You all are up. Dolgrim 1 continues to attack Clumulk, while Dolgrim 2 is now in your back lines attacking Erix.

 How are they looking, and did my damage hit?

The Dolgrim are looking fine. Your attack didn't hit, they have an AC of 15

 Didn't my first attack, which rolled 12+4=16, also hit?

Oh yeah you're right, that Dolgrim is looking really beat up then. You're still all up.

Erix tries to thorn whip the beat up one, but misses (11 for 2 dmg) while Chumulk keeps attacking

Ferocity: +6 for 8
After which he brutally charges through the Dolgrim.
To hit: 17 for 7 dmg.

I think one Dolgrim is down now.  If so, Elero will target the other one with both dagger attacks.  If not, he'll target the rough-looking one until it's down.

Magic dagger: 11 plus 2 to hit and 7 damage

Normal dagger: 15 plus 3 to hit and 2 damage

The dented Protector cannon dishes out 5 temp HP to any allies who need it.

Clumulk breaks free of melee and takes down the Dolgrim fighting Erix, while Elero steps towards the remaining Dolgrim, slashing with his knife. Mark fires another bolt at that monster, but the bolt flies wide. The remaining Dolgrim now turns on it's new prey, Elero:

Morningstar against Elero Attack: 21 Damage: 5 Piercing

Spear 1 against Elero Attack: 20 Damage: 4 Piercing

Spear 2 against Elero Attack: 18 Damage: 5 Piercing

You all are up, the last remaining Dolgrim seems intent on fighting Elero to the end.

Elero reels from the blows, losing all of the protection the cannon granted him, plus some.  Then he steels himself and fights back, something he wouldn't have thought himself capable of a month ago:

Magic dagger: 12 plus 2 to hit and 7 damage

Normal dagger: 21 plus 3 to hit and 3 damage

The Protector Cannon pulses out 9 temp HP to anyone who needs it.  Elero definitely does after that assault.

Erix tries to pull the Dolgrim away from Elero with a Thorn whip

To hit: 23 for 4 dmg and 10ft pull

While Chumulk goes for another attack
Ferocity:+2=5
Brutal Charge:
To hit: 22 for 6 dmg

Mark will either shoot the monster that is almost dead or start attacking the one who hasn't been hurt if the other is already dead. 

Attack: 19 + 3 = 22

Damage w/Sneak Attack: 11 + 8 = 19

The Dolgrims go down and now you see the nature of the shrine before you. At one time, this façade would have been imposing. It combines classical architectural elements, such as columns and arches, with flutings and curves suggestive of monstrous tentacles. Much of this beautiful stonework is now tumbled down. Cut stones as tall as a man lie scattered across the broken flagstones of the former plaza, where pools of dripwater stagnate. A flight of broad, moss-covered stone steps leads up to the entrance, a set of bronze doors green with age.

"Ok, those were horrible," Elero says, eyeing the wound the Dolgrim gave him.  He turns his attention as the dented Protector Cannon marches up beside him, and he kneels next to it, spending the next minute casting Mending to restore its original shape (and HP), while the rest of the Rouge get their bearings.

"Everyone ok?" He looks around. "This place looks creepy.  We should proceed with caution." He picks up his Infused light and puts it back in his pocket, dousing its luminance.

Erix looks at the facade befoe moving towards the entrance. Do the doors seem locked?

Mark will yank his bolts from their body and clean them off on the monster's skin. Then he will nod about being careful. 

The doors don't seem locked, you could probably open them if you push hard enough.

Erix looks at the others "Shall I open them?"
