Hadran will use the rope, as he is not very strong. He will also cast Guidance on himself, and anyone who hasn't climbed up yet (including Feng). Add d4 to your check.

Acrobatics check: 9 + Guidance 2 = 11

Hoping that the rope gives advantage? In which case, 11 + 2 Guidance = 13

Xing helps Alexander up and eyes Feng worriedly. He looks at Feng, he looks at the rope, and he looks back at Feng. “Yeah... that’s not happening.” And ties the rope to a strong point in the area.

Donar will be the last one to climb up. Using the rope to help him.

Athletics: 13 + Guidance 4

//If rope provides advantage 6//

OOC: Feng would probably try without the rope first, then use the rope if he runs into difficulty partway up.

12+2 from guidance.

(If adv.: 9)

OOC/Edit: wow ... dice roller hates me today, too :P

OOC: What experience are we at? I forgot to update my sheet

The entire group reaches the top without any major difficulties.

Alexander looks out, now that he is on top of the building, to try and see the new view of the Outpost.

Perception: 19

Xing on the other hand is going to look around the wall and try to assess what exactly happened here, Investigation: 4.

Feng looks around to see if there's anything/anyone he can smash with his ax. Perception: 20

OOC: We're currently sitting at 70xp

Alexander sees that the roof of the outpost is covered in corpses of creatures like birds, horses, and lizards as well as the mutilated bodies of several humanoid creatures, on the sides of the outpost are four towers equidistant from each.

Xing makes his way around the roof and sees that several holes have been torn out of the building, there are scorch marks surrounding them and wall around them is cracked and looks like it's bleeding.

Feng only sees the dead on the roof and the maggots that writhe among the corpses.

Xing sinks slowly into his neck feathers. “Dead.- Lots.- Walls are-... bleeding.- Bring the kids- fun for the whole family...”

"I concur. It would seem that everything around here from humans, to birds, have died due to all of this. I see four more towers around the outpost. It might be a good idea to check them out." Alexander stated, pointing towards the towers. 

As Alexander says birds, Xing wraps his cloak tighter.

Feng decapitates the dead (just in case), then goes over to one of the holes near where the wall is oozing blood. He sticks his finger in the blood and takes a tiny taste, just to see if he can tell what the blood belongs to.

"Walls don't normally bleed. This is probably a bad idea..."

OOC: I've no earthly clue what skill that would be. Nature? Perception? Hopefully not Medicine lol

OOC: Maybe Arcana?

OOC: Probably depends on what's in the blood... And if it drinking it doesn't kill you :P

Whatever the check is Donar will cast Guidance on you for the wall tasting. 

OOC: I'M IN SUSPENSE! lol Also, to those in the US, Happy Thanksgiving!

OOC: Happy Thanksgiving!

OOC: Indeed! Happy Thanksgiving!
