Bharag attempts to break contact with the Emerald Claw: he needs to break the pursuit before he starts arranging a counterattack.
19+2 (Rethlin's assistance)+2 for being 100 feet away =23
The Emerald Claw driver makes his check.
1d20+1=5
The party hears the Emerald Claw skytruck pass over their heads as someone shouts. "Kill them all and let Green Gloves interrogate their corpses!"
The truck continues on past you, feeling its way through the clouds.
Thus endeth the pursuit and the round.
Below you is traffic and a few spacious balconies where someone could set down a skycab. A plume of smoke is rising up from below you: the source is lost to view without descending.
Spot checks all around please?
Also, Bharag, you can try to establish pursuit yourself, but you'll have to rise back into the clouds to do it, and Zook has been making nervous noises about the skycab falling apart.
