All your attacks hit. After progos second arrow which flew trough the jelly with amazing speed, the jelly losy most of it integration and was on the verge of disintegration. That moment was exploited by Teyncaryn who smashed to to slosh with his staff. 

After that i took the liberty to rearrange other attacks to the second jelly, and tryncaryn using altar(jelly is above altar) as a step stone jumps and kicks that frozen jelly. After that Goraseth goes as well and plunges his Yklwa up, piercing the same jelly. In nearly the same time Tharanau pierces it with massive ice spike and keeps it frozen.

Jelly can not move much but it drops from the ceiling and tries to land on Goraseth. (flavour for attack) which is a move that Goraseth was not expecting thus did not manage to avoid it and gets 6 bludgeoning damage and 4 acid. 

« Ahhh !! It burns !  Get it off me now ! » scream Goraseth.

tries to attack the jelly on himself but it is too hard (attack 8)

Tharanau advances again towards the entrance of the hall and shoots another ray of frost at the ooze (23 to hit for 2 dmg ((sorry, I accidentally pressed the button for dagger damage, please disregard))) this time staying in the hall and not returning to the hallway. 

Tryn hops to the side when the ooze falls from the ceiling but he quickly realises that it wasn't actually falling on him. No, Goraseth, is buried under it! He summons his courage and batters the ooze with staff and kicks. "We're at it, Seth! Hold out!" 

Action: crit with 25! for 6 bludgeoning damage.
Bonus: crit fail with 6 for no damage.

Progo keeps his feet and draws another arrow. "That's the last one from the ceiling, incase you were worried."  (BA Steady Aim)

Attack: 18 Damage: 5

8 actually hits so goraseth can roll damage, and progo should you not add sneak damage?

9 of damge

ok that does it, second jelly is no more.

Progo's additional sneak damage: 12

After the jelly flops to the floor and doesn't move anymore, Tharanau tries to look around the room (investigation 7)

Goraseth grabs his amulet and quickly heals the acid burn on his skin. Bahamut's power is strong ! (+5hp - Lay on hands)
He will then start to investigate the room (Investigation 16)

Goraseth you find some other hidden passages, as well as cavity in on of the pillars. The secret door in the pillar conceals a cavity packed with dwarf skulls that tumble out when the door is opened. At the bottom of the cavity is an unlocked stone coffer containing 15 gemstones worth 10 gp each.

Secret doors, marked as white lines

Goraseth picks up his torch and shows his discovery to all "I keep them in my bag for now, we will share after. Where to now ? There are three passage..."

"I'd say we remain on the Southern side for now. Quite secretive these greed domain clergy. Every door but the main entrance is a secret door!"

"Progo agrees, southern hidden door woukd be best to explore next. Progo likes to clear areas out systematically to ensure safest path of return if the unlikely event of Progo needing a quick exit. Plus Progo is interested in seeing if this will lead to the discovery of the other side of rock block path."

"Alternatively, should we report back to our dwarven friends that we cleared out the jellies? Given that there isn't any obvious way how they could have got deeper, they must have meant these two. We could already collect our reward and then continue on in here." 

If no one objects Tryn hurries quickly back to the Dwarves to report and collect their reward, and then returns for the opening of the door.

« Nah, let’s finish checking entirely. There could be more of these things “

"Progo agrees with Goraseth, would seem kind of sad to collect reward for dispensing a few jellies and just to have more in the very next room. Not to mention, the dwarves seem nice enough but Progo isn't sure they wouldn't turn on us if we stumble acrossed something they want to keep for themselves." 

Upon entering opening the doors, you see before you a corridor (5feet wide) that curves to the left after 15 feet. The curve is filled with rubble but it does not appear blocked.

"Very well, let's advance with caution". Goraseth walks slowly with his torch, looking for hidden cache, and possibly other yellow ooze... He tries to move some rubble when it is possible.
