Having collected what useable supplies he was able to find, Dofando strings the bow across his back and straps on the quiver of arrows.  Then when sword in one hand and dagger in the other, he goes to explore the eastern exit to the room and what lies beyond.

(My first post just said that there was an exit to the east and west...I never got around to exploring for you to elaborate...are these open hallways or closed doors or what?)

Strength 10

@Bounces

Donfando leaves the east exit, and into the passageway beyond which quickly curves to the south. After taking the bend, he sees someone halfway down who appears to be investigating the tunnel. He quickly realises that it's another challenger.

(Dofando and Rac are in the same passageway.)

@Dreamhobbit

Ushala tries to move the lid, but it's too heavy.

Immediately pressing himself against the wall, Dofando attempts to not be seen by the other challenger.

Stealth: 9

He sheathes his sword and dagger slowly and quietly unslings his bow and knocks an arrow, taking aim while trying to determine if he has been noticed or not.

(As I understand it, unless he is on active alert the stealth roll would be versus his passive perception, right?)

Next he tried the sarcophagus with the sword. Strength : 20

Rac

Realizing he doesn't have the weapons to hunt ghosts with, Rac will head back and try the west passage...

Yeldor make a slow circle around the room looking for anything: traps, tools, doorways, evidence of anyone having been here - "This is too good to be true, but will be a nice place setting as King".

Perception: 20

GM, as Rac turns his back what is my distance to him?

@Bounces

(I would say that yes it's against passive perception, and you are twenty-five feet apart)

(Roll for initiative)

@Dreamhobbit

Ushala tries to move the lid on a different sarcophagus but still fails to lift this lid.

@Bugen_Badluck

Rac starts to head back the other way but realises that passages have changed behind him.

(Roll for initiative)

@Grisha71

Yeldor notices that the northernmost table has a couple of loofah gourds, which are missing from the southern table.

Yeldor inspects the gourds and the table with then more closely.  Praying to Ubaste for guidance, “These gourds are for eating and washing - is this a table of clean food?”

Smelling the gourds and food - Investigation: 4

If nothing is detected as poison or rot, Yeldor will eat of the bread and fruit and drink any water if present.

Constitution save: 17

@Grisha71

The food is delicious and is fresh. There are ten pounds of food in total available on this table.

He steadies the bow, slowly breathing out with the arrow pointing directly between the shoulder blades of his foe. 

Initiative: 16

Shocked at how much the ice damage seems to have weakened him Ushala tries the final sarcophagus. Strength 20

Growling with frustration he makes for the western exit and studies the door for traps or markings. Investigation 3

Yeldor quietly moves the place settings, ties up the table cloth as a make-shift sling and puts the remaining food in it, and slings it over his shoulder.

seeing no other exits from this room, Yeldor will head east back to the last intersection and quietly move south (if it keeps going south).

Stealth: 16

Rac

initiative 19

@Burgen_Badluck @Bouncces

As Dofando takes aim at Rac, but before Dofando can fire his arrow, Rac disappears around the corner of the passageway. As Rac continues through the tunnel, it curves around to the north. On his right he sees another passageway that comes to an end. As he moves north he enters into fifteen by seventy foot room. He sees a tabaxi investigating the western door, another contestant. There are four sarcophagi in the room.

@Dreamhobbit

Ushala sees no traps or any unusual markings by the door.

(DM Note: Rac and Ushala are now in the same room.)

@Grisha71

Yeldor makes it back to the intersection and heads south. The passage goes south for twenty five feet before curving to his left. He continues for fifty-five feet before he finds another passage to the south.

Ushala will attack Rac in a rage Attack: 12 Damage: 6

Yeldor will double back north to the end of this passage to the east-west T-intersection and head east.

Stealth: 10

@Grish71

Yeldor heads back to the intersection and heads east instead. The follows the passageway as it curves south, then east, then north, then east again. After a few more feet, the passage way curves north then east. Then it is straight east until Yeldor finds a room that is twenty-five feet wide, and fifty-five feet long.

The room is full of flowers and vines, and a wooden mezzanine platform the runs around the room. An exit to the north is frozen shut, but another exit, different from the one that Yeldor just entered through, can be seen in the western wall.

Rac

Rac gives a guttural growl at Ushala.....and attacks with his claws
