I'm trying to create an encounter where PCs are climbing a vine or rope down a 100ft shaft. About half way down, a creature flies up and attempts to grab one of the PCs to fly away with her.
The monster I'm using (a sabosan) has a fly speed of 40' (good) and the Flyby Attack feat (if that's relevant). My understanding of the rules is that:
- For round 1: the sabosan just needs to fly to the PC and grapple her.
- For round 2: the monster must make a grapple check and, ifto maintain the grapple. If successful, the monster (and grappled PC) can move up to half its speed with the targetmonster's speed. Because the PC would be in a hazardous location (50' in the air), the PC receives a +4 bonus on thisthe maintain grapple check. And because the grapple check is a standard action, the monster could only move 20' with the target on each turn (if the grapple succeeds).
Questions:
- Does the above sound correct/fair for the rules of a flyby grapple, or is there something I'm missing?
- Also, should/do I need to account for the PC holding onto the rope while climbing down? Perhaps give the PC a +2 to their original grapple check?
