MarauderX said:Sure, it would be similar to Tumble IMO, where anyone with 15 ranks can beat a DC 15.
Coredump said:OT: I hope you are not refering to tripping knights so that they could not get back up, and might drown in a puddle....
That is pure hollywood hogwash. Knights in full armor could run and jump and had no problem getting up or getting on their horses.
Plane Sailing said:It turns out that you need a lot less than 15 ranks... what with +2 synergy from jump and +4 from Dex I see 4th level rogues (7 ranks) regularly making the DC15 tumble checks...
While armour might have reduced your mobility and reflexes it was only a relative limit rather than an absolute one.
HarryFlashman said:If the armoured opponet chose to try to maintain his blance rather than regularly resist the trip attempt then yes, Armour penalties should come into play, otherwise I would leave them out.
