I read that some pieces of those special effect sets are found from some Iria Field bosses.
Like Golden Kiwi.
Eres correcto~ Unless things changed in KR from the time I read up on it (back when G13 was brand spanking new) different set item pieces can be dropped by the various field bosses of Iria (I want to say Rano but I'm not 100% sure). There's some brand new set effects too (as the previously existing set effects weren't the best) including skill boosting (including range for all you people whining that range gets nothing) and one even boosts blacksmithing success rates. Later on the 200 Snow Troll battle can drop various Trinity items at different difficulties but for now people will want to do Fiodh Adv for the Trinity Staff (well at least, that's how you could get the Trinity staff in test, public server may differ XD).
As a side note, people should take note that Nexon doesn't always post all the information regarding the coming update (a really funny example of this was when the fossil collection books came out and I made a few million gold selling manuals 8D). There's no indication that they're gonna do things their own way and people claim to have found NA names for various skills like "Magic Bolt Combination".
