Dex save: 10

Bazavur, you feel your left foot slip on the wet stone, but you think you caught yourself - then your right foot slips on a thin patch of moss - and you tumble off to the side.  Make an Acrobatics check to attempt to catch yourself.

Acrobatics: 16

You catch yourself on the edge of the bridge, but are hanging very precariously off the side, with angry animal noises coming up from the pit below.

As the lizardfolk you were chasing is dead, we are technically out of initiative. 

“HELP!!!!” (yes to answer the question)

Jalt holding on to the staff, casts Cure Wounds 3rd lvl on himself for 19 and then stands back up, shaking his head... I trust you disposed of them?

Tangle quickly doffs her pack, putting her bow down, and pulling out a coil of silky rope. How far is it to Bazavur?

Is Bazavur shouting 'HELP'?

Tangle is about fifteen feet from Bazavur.  Moving any distance towards him would require walking on the very slippery bridge over the pit.

Soar tells Jalt that yes, the immediate quarry is dead and the others went off after one runner. She helps Jalt up and moves toward the others. 

OOC: Could Soar's channel divinity: nature's wrath help get Bazavur back up on the bridge? Or would it just restrain him?

Soar's Nature's Wrath would prevent him from falling if he saved another DEX save, but he would also be restrained, so someone would need to lift him onto the slippery bridge.  You can try it if you like.

Tangle looks back and forth between the approaching path members and Bazavur. Then she ties the rope securely around her waist, throwing the other end towards Soar. "Hold that fast!" As soon as Soar has it, she turns to look at Bazavur. "When I am within reach, I need you to grab on to me, or the rope, and hold fast. You can do that, yes?"

“I’ll certainly try…” 

When (if?) Tangle has assurances that Soar and Jalt have the other end of the rope, she will take a step, and in a twinkle with a blast of cold air, step through to stand right next to Bazavur.

OOC > Eladrin feature, Fey Step

Soar absolutely wraps the other end of the rope around herself and steps on it, ready to hold and then pull them to safety.

As soon as Soar has the other end of the rope, Tangle will step lightly out onto the bridge, making her way slowly and carefully to where Bazavur is clinging.

Acrobatics: 22

Once there, she will untie herself and, if he can let go with one hand, she will make sure he grasps it. If he cannot, she will tie the end around Bazavur, either his torso if she can reach, or one of his wrists, if not.

If all that is accomplished successfully, she will look both ways, then continue carefully across the bridge, leaving Bazavur with a friendly pat on the shoulder.

OOC > another Acrobatics check? Two? Sleight of hand for tying the rope?

Well, Tangle certainly cannot reach down and tie the rope around Bazavur's torso - it's definitely out of reach.  Bazavur, are you going to try to grab the rope as Tangle offers it?  If so, make a DEX check to catch it with one hand while maintaining your grip with the other.  If not, let me know what your plan is.

If Bazavur says no, she will tie it around his wrist, as noted above.

Dex check: 15

Bazavur, you just... only just... manage to catch the rope.  You have a hold of it in one hand and are still clinging to the side of the bridge with the other.
