Abyssea Newbie - Procing?

[Shay]

OK, anyone have a link or the time to explain to me this whole proc'ing thing with abyssea NMs? A few people have tried to explain it while we were fighting, but I don't think I'm getting it.

Any help appreciated... thank you!

Should be in the new players' thread, but here:

Beautiful thank you very much!

At this point, this is really something that should be explained by an NPC somewhere.
