Lost Lab of Kwalish

Sam is waiting behind them seeing this very had locking mechanism 

As soon as the last door is opened, a 3rd level lightning bolt spell is cast with a save DC of 15 out of the mouth of the demonic stone head at the end of the multi-door hallway.

"A stroke of lightning forming a line 100 feet long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 32 lightning damage on a failed save, or half as much damage on a successful one.

The lightning ignites flammable objects in the area that aren't being worn or carried."

Huarache, and anyone else within 10 feet of Leann, can add 3 to their save and are resistant to spell damage.

Leann dex save: 25

Leann is nimble and is able to press against the side of the hall, out of the way of the majority of the blast. the energy that does get close to her, and those within ten feet of her, seems to fizzle a bit, some aspect of Leann causing it to loose most of its force regardless.

"Maybe we should start looking for hidden doors." Leann suggests. "every regular door seems to lead to a trap of some sort..." She will help anyone looking for secret doors.

Huarache's DEX save: 12.

His fur standing a little straighter now, Huarache stands back up as the voltage knocks him down. "No. I'm not accepting that there's nothing but a zappy statue after some of the most tricky locks I've ever seen. I'm not accepting that." He's going to look around further, maybe for a secret door around the area of the demon head, avoiding the statue's line of sight.

Dex Save: 10 

Huarache is going to drink his Greater Healing Position for 17 HP as he searches for something that means his lockpicking skills weren't for naught, because as it currently stands, he's not going ohm until he conducts a thorough search. He doesn't know watt's hidden in here, but if there's nothing here, he's going to be shocked; he doesn't have the capacitance for this kind of stress. If some other thing attacks him, however, he's going to make a volt for the door.

Total pun count: 7.

  Did you halve the damage due to resistance, thanks to Leann watching over your hsoulder and being within 10 feet of you? Also, make your perception/investigation checks with advantage, as Leann is helping you.

All your checks at max can find in this room is that the grate has a hinge, it opens downward.  It's too dark to see how deep the hole is with ambient light.

 Guys, I think Huarache has been fried.

Also Omiy’s gonna stick close to Lia and send her echo down the grate to scout around. 

I did halve the damage, and as Omiy starts to send her echo down, Huarache hands her a piton that glows in a 5 ft. radius with bright light and a further 5 ft. of dim light.

Omiy will tie Huarache’s glowing piton on her echo’s head like a makeshift headlight. 

"Is that the way of it then?" Leann asks with a sigh. she waits until the depth is determined, then will follow after the echo if not too deep.

If it's less than 50 feet, Huarache has a rope and a grappling hook, and if lifting of weight is needed, he has a block and tackle.

The hole is 50ft deep.  A flashlight (bullseye lantern) would have revealed this depth, or dropping a glow stick.  It's just a hole though.  Good thing someone brought a rope.

Huarache ties his rope to a grappling hook, which he anchors securely as he begins to descend.

Ooc: I meant it's good that you brought a rope so you're not stuck in a hole. 

Leann waits until it is determined to be just a hole. Then she sighs. "Anyone good at searching for hidden doors?" She asks the group-at-large. "I can help you do so, but it is far from my strong-point."

Ooc: There really is nothing down there, it's just apit trap.

Don't worry about time elapsed for this, (I rolled it earlier, I think 5 hours) but let's say the magma has cooled.  Now it's a solid rock floor.  It is safe to walk on.

There is also another door on the right side of the main room you have not opened.

Here is the map again; ignore the lightning bolt.  I'll get rid of it next time I update the map to reveal more as you explore.
