Gonna set this straight, Ice Trousers proc very well for mobs that are at the max Toughs at lvl 75. I use them alot on Drg, Also you "do not" need them equipped during the said effect. After i used them and ice spikes came up i switched to homam cosciales and the effect was still active and working. I first used them on Sewer Syrup as Drg/Blu 75.
I can somewhat understand Ice Spikes comming out of Body Armor. But what mob wants to be struck with icy spikes coming out of someones pants?

(seriously, wtf is up with these "FIRST NA"'s in sigs? Didn't you grow out of that "me first!" phase in grade school?)
Ice spikes - Must have the trousers on all times and it last 5 min, 5 min recast Proc rate - 5 damage to Lesser collibri (at 75) every time and proc rate for Paralyze from what I notice is as good as a RDM ice spikes. Ice shield and ice trousers stack? - no, trousers is stronger since its the actual spell and will be base on your enhancing magic.
