Mazra's Sunless Citadel Campaign

"Let's have Bones come over. Then leave it open. Whatever is in there will not be worried with it."

OK.  Now what do you do?

Check the box for traps? 

Good work and yes, indeed, let's see what secrets the dragon priest has to share, moves to inspect the sarcophagus, looking for writings, traps, latches and such...percep check, drum roll please, nat 1

(@Ragdor - You should have Advantage with the party’s help.  You take the higher of two rolls.)

By the way, you do not find any traps or writings.  The iron straps on the sarcophagus are rusted shut but can likely be forced open. (DC 15 Strength Check)

Glynt will say "that thing looks like it's shut tight, Xanth - that thing is no match for the raw power of your might"

I give Xanth Bardic Inspiriation (it even rhymed)
You can inspire others through stirring words or music. To do so, you use a bonus action on your turn to choose one creature other than yourself within 60 feet of you who can hear you. That creature gains one Bardic Inspiration die, a d6.

Once within the next 10 minutes, the creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. The creature can wait until after it rolls the d20 before deciding to use the Bardic Inspiration die, but must decide before the DM says whether the roll succeeds or fails. Once the Bardic Inspiration die is rolled, it is lost.

Xanth feeling embolden by his friend's words. Cracks his knuckles and take hold of the straps. Them rips them free like a child on Christmas morning.

Str. Check = 17+6 = 23

There are a total of six iron latches that hold down the lid.

XANTH with GLYNT's Inspiration has no problems snapping the iron latches.

(The lid is ready to be opened.  Is the party ready to open the lid?)

Glynt is over in the corner near the trapdoor ready to jump in if necessary, has picked up his bow and is waiting to see what happens next.

Ready

Just a second there lad, pulls a small vile of some type of liquid from his belt, from a holy spring that flows from the melting ice at the edge of the world, holy water, sprinkles a little on Glynt, Portia, and Xanth, while muttering a prayer of blessing - cast bless - You bless up to three creatures of your choice within range. Whenever a target makes an attack roll or a saving throw before the spell ends, the target can roll a d4 and add the number rolled to the attack roll or saving throw. Looks at Erky, sorry mate but I can only get three of us.

Glynt will try to stop before he is blessed and say "Ragdor If you can only get 3 people I would suggest yourself over me, if a fight happens you are more likely to be closer than I am."

Portia accepts the blessing. And draws her swords

Xanth "Thank you Ragdor."

(Moving on.  I will assume Ragdor takes the other Bless.)

ERKY considers GLYNT's plan and moves to the same wall.

With an assist from RAGDOR, XANTH removes the tomb's lid.  And with no litte amount of PORTIA's prescience, the party sees a flash of green light when the sarcophagus is opened.

In the coffin is a troll! It’s dressed in rotted finery, but its jewelry and rings adorned with tiny silver dragons still sparkle. The creature’s body is shrunken and elongated, and its flesh is a rubbery, putrid green. Its whitish hair is long, thick, and ropy. Its beady black eyes flash open, and it snarls.

(No surprise here.)  ROLL FOR INITIATIVE (Also, give me your first round's actions.)
