FLYFFU Solo dualing Guardian Sanctuary

Flyff Universe - Server FWC
Soloing Guardian Sanctuary nightmare as dualing Blade & RM
Helped with a Psykeeper using Firestrike for debuff and be a bit faster (etw 1:30-2:00 min)
RM :
500 int & 200% casting time
Blade :
100% critical chance
170% critical damage
BOSS STRAT :
First pull the boss on the right side MANDATORY
At 165M every player except tanker/dpser go to the other side
The boss will clone himself when HP are under 162M, so is there 2 options
First options as showed above, stop hit at 162.XXXM, wait until the boss cast an aoe and then hit him to go under 162M and blink behind the boss to pull only the real boss when clones appear
The second options is a bit different than the first, but instead waiting the boss cast an aoe, just continue to hit and blink as fast as u can when the boss reach under 162M
