Are any of the gaps in the rocks large enough for Isk to chuck a stone through? Also is there is a light source on the zombie-side of the rocks?

(There are enough gaps to chuck a stone through.
It is dark on the other side, but not completely. There is a very faint light from somewhere further back, but you can't get a clear view with the barricade in the way.

Brin may not know why these events are going on, but he does know what is likely ahead. Ana mentioned (before the Feywild visit) tracking a Corpse Flower, and the drugged villager mentioned it too. The plant has the stench of decay, and it turns dead bodies into zombies.)

Isk turns and says to the group, "I think we've found what we've came for."  He takes the stones he had cast light on and tries throwing it through one of the gaps into the room, hoping the draw the zombies' attention away from the door while the group figures out how to open it.

Reverie bites her lower lip as the shock of a scene in the tunnel crawls up to her mind. "Never thought there will the undead here," she murmurs in frown before she looks back at Brin. Then she frowns, remembering the past event where the Watchful Guild has been attacked the zombies before and a possible connection with the followers of Talona... Then she remembers the encounter of Trimyrai's two villagers with the winter hag. "There was one time these kind of monsters came attack the guild before, and met the followers of Talona as well. I am thinking that we might be entered into one of their strategy place. Some of them are maybe..." She stops before giving a brief glance towards Trimyrai. And then, she walks towards Iskander's side for a moment, murmuring under her breath. "Maybe we can try to lure the undead ones with a distraction, and act fast to bash towards the door? Or we could turn our way to the west from where we came from."

Trimyrai: (to the party) "are we trying to sneak around? we could easily take down one zombie, and if we are here to destroy the corpse flower, we might as well take out the zombie too."

Isk nods to both companions and says, "Aye, my thought was the glowing stone would distract the zombie, or zombies, we can only see the one but there might be more, such that when we open the door we had a quick minute to take stock of the room before attacking."

"Makes sense to me." Brin says with a nod. "Ready to thrash some undead if you guys are..."

The pebble with Light shows that the passage goes another 10', then turns left. The faint glow comes from around the corner.
(If there is a room around the corner, your Light will be easily noticed, like the gap under a bedroom door.)

The doors and the rock pile are to keep the zombies in, not to keep you out. The barricade and the left turn of the passage prevents a larger group of zombies from gathering and pushing their way through.

It will be easy to move aside the rocks and stone slabs to let you continue forward, but the manual labor will take time, and you do have a pair of zombies waiting to greet you.

"I'll go ahead and clear the path as you guys clear the block..." Brin says. He casts armor of agathys on himself at 3rd level, then he uses Bastion of Law (spending 5 sorcery points.) With his defenses set up, he casts misty step to teleport past the barrior. He immediately attacks the zombies.

((Do we need to roll initiative now? I'll go ahead and roll. 10 ))

Ana sees no point in waiting to clear the passage. From her point of view it's protecting them from the undead. She points at one of the zombies and calls down a column of radiant flame upon it.

((sacred flame - Dex save DC 14 or take 6 radiant damage))

Isk laughs, mostly out of surprise at Brin's initiative, and will follow up with a duo of eldritch blasts (if they can get through the gaps in the rocks).

• Attack: 26 Damage: 10
• Attack: 9 Damage: 14

(It is only a pair of zombies. Since Brin used up some resources, let's say that the Armor of Agathys is down to 5 temporary HP, but otherwise the party knocks down the zombies and radiantly bakes them to stop them. The passageway is clear, and 10' ahead it turns left.

Everyone can roll Initiative.
I'll need to know the marching order. The passage is 10' wide, so up to 2 across. I will adjust the initiative order so that the ones in front go ahead of the ones behind, since you have time to organize.)

(The armor of agathys would be the last thing to be depleted, just before his HP. The bastian of law would go first, maybe he loses one of the d8s from that? Otherwise that was super expensive and those two zombies did well over 5d8 +10 damage to him all on their own... With an AC of 19 and access to Shield, I would guess they wouldn't even have gotten a single hit in.) Brin initiative: 8

Also, Brin will be in the very front, leading the charge around the corner.

(OOC: I did overlook the Bastion of Law, and thought about what what you said.
Instead of any damage to the Armor, change that to 1d8 removed, unless you'd prefer to swap that for a use of Shield. )

(1d8 removed works for me. Thanks!)

As support, Ana will be in the rear.

As for Reverie, she will stand beside of Brin since she is a paladin. (She can move to the best position to protect everyone c: )

Initiative - 23

(Edit: NATURAL 20!)

initiative: 7

Isk will follow behind Rev and Brin, with his glaive at the ready.

Initiative: 14

So...?
