How to defeat Golden Pig Cave 5 as Choryeong.

I set up my energy as 5ap/5dp.  To help with survivability as well as keeping damage on the field.

I used the following skills on Choryeong on bosses as i feel this not only helps with survivability but as well dishign out the most dps as possible with flexable movements when needed.  I have Perilous Waltz and Absolute Butterfly Step with Auto-Equip off, so i can use them when needed during auto combat.

You'll start out the fight as any fight by engaging the boss and just letting the skills go preferably starting with blossoming death as it has forward guard on it.  When you see any attack animation go towards you you'll use evasian while pressing your movement towards him to move you behind him.  The times i did not use evasion and rather a skill is when i see the attack animation that puts a small red circle under my feet then i used Perilous Waltz to put me behind the boss and activating a 2nd time to extend the duration of the invincibility.  When you see the boss talk as in you see words appear on the screen that means he will be doing a massive AOE that fills up his little fighting arena.  During this time i use Absolute Butterfly Step and extend its duration by holding down the button of that skill so the invincibility extends throughout his AOE attack on you.  Then the process goes back to how it was by using evasion, then perilous waltz then absolute butterfly step accordingly.  This will knock out difficulties 1 through 5 with no problem.  

Best of luck :)
