Quillary marches towards the door and the cultist, trying to smack her out of the way with her magicked club.

Attack: 12 Damage: 6 

(C5 is still standing after Quillary's clubbing, but in very bad shape.)

Hildigrim to go.

Hildigrim mouths something in the magical silence and fires another arrow, this time at C5 (who is being buzzed by Volo).

Attack: 21 Damage: 8

Sneak attack: 8

Hildigrim moves as close to the door as possible.

The last cultist falls after Hildi’s arrow hits.
(The magic ring that made the spectral ram attacks looks very pretty, but there will be time to claim it later.)

The door to the secret room remains closed, so you don’t know what Viallis is doing in there.

Party is up.
(indicate if you still want Silence active, or if it should end.)

Quillary makes a motion to Drusk to end the Silence spell, a shushing motion with a throat chop. After he does that, she hefts her shield and opens the door, rushing through if she can.

Drusk ends the Silence spell. It is still quiet, as everyone mentally prepares to continue the pursuit of Viallis.

Quillary opens the secret door, to reveal a dark corridor. No one sees anything in the corridor, but a voice is heard ahead, finishing the chanting of a spell (reaction of a held action).
A hail of rock-hard ice pounds the area around the party from the completed Ice Storm spell.

Everyone roll a DEX save vs. DC 14.
Half damage for a successful save. Failed save means full damage: 6 bludgeoning and 17 cold damage.
The temple floor in a 20' radius around the party (and the corridor ahead) is now difficult terrain for this turn.

Past the secret door is a 10' corridor to the west, which connects to a 10' by 15' room. Most of the room is out of sight (around the corner to the south).
There is only the dim light of a torch from the part of the room that is out of sight.

Drusk DEX save: 12

(EDIT: Those damage rolls of 6 and 8 were terrible.  Even the dice gods hate Viallis.)

Quillary grunts and tries to dodge, but pushes her hand out and her spores fly to intercept the ice chunks aimed at her, they get a cold hue and swirl back to her.

Dex Save vs DC 14: 24 

Reaction: cast Absorb Elements with a second level slot. She has resistance to cold damage, and will add 2d6 cold damage to her next attack.

So, 6 bludgeoning and 4 cold damage and 2d6 cold damage with her next attack./

(i've always been a little confused about how the barb danger sense works.  I have advantage on dex saves vs effects i can see.  I'm not sure if, for spells, i have to see the caster or just the effects of the spell.  The latter makes sense to me, so i'll roll with advantage but feel free to take the first number instead if you think otherwise.)

Dex Save: 11

oh, it didnt apply the advantage...first roll takes it!

(So after rage reduction, Jorin takes 1 bludgeoning and 4 cold damage. I'd say Jorin is almost happy for this minor damage, as it keeps his Rage rolling.

Hildigrim still has to roll his DEX save.
But everyone else can post what they are doing. I don't know if you are charging in, or doing some other action, spell casting, whatever.
With the ground being difficult terrain, 30' of movement will get you to the end of the corridor past the secret door, and let you see what is in that room.)

Quillary scrambles over the difficult terrain to take in the scene (and decide what to do with her Action and BA then).

Oh yes, Jorin is charging through the storm, using his full 40 ft of movement to get through the door.  The goal would be to get into melee range of V, either with his regular movement or with a dash action (unless there is something totally wild going on in that room lol).

DEX save: 28

Hildigrim just manages to bob and weave out of harm's way. He then follows Jorin in.

The result was a 14.

(With only 25' of movement, Hildigrim won't be able to reach the room this turn, unless...)

The party charges through the secret door, although sliding and slipping on the icy floor slows everyone down. With Hildigrim falling behind, Drusk uses his Action to push the halfling forward 5', like a curling stone.

This small, dark chamber, barely illuminated by a pair of candles, has a small table along the southern wall. It supports a golden urn, about 3' in height. Along the western wall is a bookcase stuffed with books and scrolls, many of them old and worn.

Obviously, someone cast that Ice Storm spell from this area. But there is no sign of anyone here.

Quillary speaks a few words in her guttural language, and a sheen of glowing ash descends on the room…

Action: Cast Faerie Fire in the room. If a 20’ cube does not fill the room, she will shade it away from the party, as she’s pretty sure he wouldn’t be near to them. Dex Save vs DC 16 to avoid it.

(No other exists in the room?)

"Where are you?!" Jorin yells and then smashes the urn in frustration.

Quillary does the procedure to cast Faerie Fire, but nothing happens. Nothing in the room gets lit up.

For Quillary only:

Jorin smashes the urn, making a huge dent in the side and sending the top lid flying to the side. A cloud of grey dust erupts from the top, like a bag of flour that is smashed.

For Jorin only:

Drusk already used his Action to push Hildigrim into the room with the rest of the party.

Hildigrim can take an Action. (If nothing better comes to mind, he could Dodge, or use the Action for a Perception check of the surroundings.)

Thanks, Drusk. If it's not too late, I could dash for another 12.5'. I just don't want to rush headlong into Vialis's arms.

If Quillary's spell doesn't reveal our quarry, Hildigrim will cast detect magic and continue moving toward any new magic he senses or further into the room if he doesn't sense anything initially.

Nevermind. I can only cast it as a ritual at this time.

Hildigrim makes a perception check! 23

For Hildigrim only:

(At this point, only dialogue is allowed from the party.
No more Actions or movements this round.
When everyone is satisfied, I'll do Viallis's turn.)
