What lvl are you?
Pretty much the winning order is: Chi Blast, Provoke, Stun/Dia in these things.
Farming tips... hmm, since I don't know your lvl ill give some generic ones.
-Don't farm one thing for long periods of time, you go insane and make it worst.
-Get all your gobbiebags, and keep your inv full of drops. When you get full sell junk to the vendor at a outpost/town. It adds up and you should learn prices on what things are worth so you dont accidently sell a 5k item for 235 gil.
-Explore wherever you can to find new farming spots. Like the secret crawler farm in Bubu Penn.
-Sell quest rewards unless they are for your job. Same thing for RSE. You can always buy that stuff back later and when your character is high enough its pocket change
I could probably give better if i knew your lvls
