Is it worthwhile to slot damage procs (ex: Eradication: change for energy damage) or other procs (ex: energy manipulator: chance to stun) into damage fields like lightning field? I thought I heard somewhere that they only have a chance to proc every ten seconds? I have damage procs in my /traps MM's caltrops and poison trap and they work well.
As a side note, is there a good resource to look up this kind of thing? I didn't see any details like this on paragonwiki. For example, I'm interested in what causes Performance shifter: chance for +end to proc.
Thanks,
