obi

So I recently got Sea access, and I have been working on farming what I need for my obi's. I currently have BLM and RDM at level to use these. What I'm wondering is do these obi's work on Enfeebling Magic as well? Or just nukes? For example, using the Hyorin Obi for Paralyze? Worth it to use or...

Anyone know which mob has a fairly high drop rate on these? i've killed for hours and still have not gotten even one to drop and i need 3 for my first obi. Thanks

Anyone know if it's better to wear an obi over Penitent's Rope when casting elemental magic? I haven't had a chance to try my rarin obi, and am wondering if I should farm for the other seven obis. Thanks in advance.

Ok well, I am a ninja...fairly broke one :P but farming will fix that but anyways my question is the Heko Obi +1 has the Added Spell Interuption Rate +8% does this count for Ninjitsu as well? know it all Falkner says it doesnt but I'd rather ask my community family. :P
