Seth will throw a dart at Toxic: 

Attack: 25 Damage: 8

Toxic, if this deals damage, please roll concentration, again DC 10.

Toxic catches the arrow.

13

nice try.

"We are in the final stretch! Khan has finally caught up to LeShanna! Who will get their last key bag and return first!"

Initiative - Round 11 - Whisper has an action available from Round 10

1. TOXIC [Concentrating on Silence] (22) - Attacks Seth
2. STOLAS (19) - Helps Khan
3. KHAN (16) - Continues to search for the 2nd key bag
4. WHISPER (15) - 
5. LESHANNA  - Finds second key bag and continues on. and ANASTASIA [Under Toxic's [spell/Silence[/spell]] (9) - 
6. SETH [Under Toxic's [spell/Silence[/spell]] (7) - 

Toxic uses his action to throw the dart back at Seth. This is too easy.

Attack: 27 Damage: 8

Action 1: LeShanna casts haste.

Action 2: Attempt to find 2nd key bag - Selight of Hand Check: 20

Bonus Action: Bladesong - AC increases, along with Concentration checks and advantage on Acrobatics.

If I find the key bag, I move 80 feet to the final log.

Stolas will search for Key #2.

Slight of Hand: 8

Khan also searches for the 2nd key bag: 7

Come on! We are so close!

"Toxic launches an attack on Seth and the dart hits! LeShanna finally finds the second bag as Khan and Stolas continue to search!"

Anastasia, you still have your action. You explaining what Stolas is doing is just an explanation, it does not take any action to do.

Whisper smiles and cast Sleep 2nd level, on the bird and Goblin.

Sleep: 32

Khan and Stolas are actually over 180 feet away from you and out of range of sleep each of the 3 paths are a continuation of the previous, a straight line, just like the middle paths coming back up to the puzzle. If you choose a different target, you can keep the roll otherwise, that roll is lost and you can choose a new action.

(Can she hold the action until they get in range?)

(Can she hold the action until they get in range?)

RAW, when you hold a spell, I believe the spell is used, but I don't neccesarily like that. I will say until further notice, Whisper is holding her action until the goblin and bird get within range and will cast it. As always, you can change this whenever you want, as long as it's before the trigger.

She'd lose the spell because she be holding it for multiple rounds.

Yeah, but I think of it more as a "I will cast it when they get within range" moreso than "I cast it and hold it", which I know is RAW. However, all this really means is Whisper is consecutively passing her turn, until her targets get within range, and during the turn it seems most likely, she will then ready the action.

Initiative - Round 12 -

1. TOXIC [Concentrating on Silence] (22) - 
2. STOLAS (19) - Finds 2nd bag of keys.
3. KHAN (16) - Attacks Toxic and sends LeShanna to another plane, then moves closer to the final log.
4. WHISPER (15) - Passing
5. LESHANNA  -  incapacitated with 0 speed and ANASTASIA [Under Toxic's [spell/Silence[/spell]] dodgeing (9) - 
6. SETH [Under Toxic's [spell/Silence[/spell]] dodgeing (7) - 

With their actions from last round, are Anastasia and Seth using their attacks against Toxic? That's what they've been doing the past couple turns.

Anastasia is going to dodge, because shooting Toxic isn't going to accomplish much at this point.

Seth will dodge as well then.

Anastasia, what action does Stolas take this round?

Attack 1: Banishing Arrow against LeShanna (Only used on a Hit: Charisma Save DC 13) - Attack: 13 Damage: 12

Attack 2: Sharpshooter Arrow against Toxic - Attack: 17 Damage: Unable to parse dice roll. - whoops this is supposed to have +10 damage for sharpshooter, you minus 5 on the hit.
