I'll try and post this without using the colourful language I've just been using in quest.

Chain tripping we have already agreed is more than an inconvenience and a minor nuisance.

So why are multiple Driders allowed to chain trip you with their Line Trip?

I can understand why a STR check is needed to break free from it, that makes perfect sense. Even if a save only on your STR modifier does seem a bit brutal.

But why is there no DEX or Reflex save to avoid the bloody thing in the first place?
