Kasman, First off, its sad to see that you missed 3 levels of thorny trap asit is a lvl 52 ca..not 55.Other Rangers probably have found unique things to do with this ca...Im only lvl 54so still experimenting with it and pretty basic but my main use is for multi encounters. Find a grp of 3-5 (have done up to 4 lvls above me solo con or down arrows). Sneakup as close as you can get assumming at least one sees thru invis and place itin a semi straight line from where you intend to attack from. After its down..just backup to max bow range and Fire away.I like to start with Natural selection as its a good grp attention hitter anddoes good damage. Also since not all are within the damage area its nota waste. Now after natural selection, they fly/run over the trap and are trapped(rooted) for up to i believe 2 mins with a break on damage. However they are nowall closely packed together and this is where a good storm of arrows shot just ripsthem all apart....Pick off survivors one by one if any.You also may get one that will break immediately after trap goes off but they areslowed somewhat so just target them for a single triple shot and short melle ifneeded. Then back to the trapped grp. Remember, the trap lasts for a long timeso dont need to rush..deal with immediate threats and youll be fine.I would also like to see some ingenious Ranger uses with this ca.
