He then breathes out towards the door.

Kiric breathes fire! It doesn't take much insight to realize that what he drank was Potion of Fire Breathing. The door is undamaged, being made of stone.

“That looks like it’ll come in handy,” Kierro says, opening the door.

Asmodai will take 3 vials out and fill them with the Potion of Fire Breathing.

Soar does the same with two vials!

You have used up all the potion in the fountain.

Five dusty sarcophagi stand on end in this silent chamber; three stand on the north wall, and two stand on the south. The carved stone sarcophagi each resemble a noble elflike humanoid in ceremonial robes. A shrine carved of obsidian is set in the center of the west wall, on which a single candle yet burns.

Kierro walks close to the shrine and uses light to get a closer look at it.

Investigation, if needed: 5

Soar, seeing the sarcophagi, uses her divine sense to try to ascertain whether they're alone in the room. "I wonder why the goblins and the kobolds haven't taken that candle..." she says, from just inside the doorway. She looks around the room, trying to spot anything noteworthy. (Perception: 14)

Dwaye asks Asmodai ”Could I have one of the vials? I think it would be best if we share it” 

After saying that and taking the vial (if offered), Dwaye moves forward into the room, towards the shrine, but not too far in, just enough that he can still back up if need be. He also readies his Warhammer to attack anything that comes out of the sarcophagi.

Heia is curious about the Elvish sarcophagi, but will linger near the entrance of the room. She looks at Dwaye, having pulled his warhammer, one eyebrow raised quizzically. 

Soar notices, in addition to the sarcophagi, the obsidian shrine and the burning candle, a potion vial and what looks like a whistle made of glass.

(Does anything ping her divine sense?)

Kiric sends a mage hand over to grab the items, one at a time. He then pulls out a bag to put them in.

Soar senses undead in the sarcophagi; they are not moving.

Or at least they weren't, until Kiric started grabbing the items from the shrine. Five skeletons come out of the sarcophagi, upset that their resting place has been disturbed!

Heia will rouse from her resting spot against the wall and slips her beaded string over her neck. She pulls her quarterstaff from its sheath across her back and sets about spinning it in a few figure 8 patterns, reminding herself of the practiced feels of its heft. 

Initiative 12.  

Kierro, seeing the skeletons awaken, slides his shield onto his arm as it and Kierro begin to glow softly in the unlit chamber.

Initiative: 8

Kiric pulled out his wand as he prepared to channels magics not meant to be wielded by mortal men against the skeletons warriors his group faced.
