The effect imposes Vulnerable as 1st Degree (presumably getting spun around or narrowly avoiding the rocket to make you an easy target) and Prone as 2nd (as you say, knocking you off your feet). Since they are inflicted Conditions, though, they need to be resisted each turn until successful. So a low-resisting or bad-rolling target could spend several consecutive rounds Vulnerable or Prone.* Now that I've that about it while writing, seems to me the best descriptor to support both of those Conditions would be getting the wind knocked out of you (which ties in nicely with Fortitude-resisting). That would also make this a great build for the classic and oft-maligned Boxing Glove arrow.legend wrote:The Rocket Arrow knocks you off your feet.JDRook wrote:Incidentally, not 100% sure what's happening with the Rocket Arrow. How does it work?
*Prone would be arguably the weakest Condition of all, let alone 2nd tier, if you could simply use a Move action (or less) and no roll to get over it, so I figure you need to resist first (keep your balance without slipping on oil or succumbing to vertigo or whatever) and then use an action to stand.
