fastest ASSA lvl 99 way

[The Roger]

Nice, but actually it becames the least efficient way because it requires at least one more player on the SL to your the sin, which alone here cannot be done (no double clients).

I still suggest to do Juperos F1, better with a 100 PD setup rather than a flee build (but yeah, one needs to gear up for the 100PD build).
When i trained my extra sins, i did juperos from lv 67, without killing the wind venatus because dex/hit will still be too low at those levels, but the first full mob even without those will grant 3-4 levels, lol. From there onward the killing rate will only become better and better.
I'd say the only part hard to come by is the morrigane's manteau because nobody goes to thana tower up the top, and the properly carded jur. Though one can replace the garment with a choco/angramantis card and a hunterfly pet to reach 7PD, and pump LUK 10 points more to match the morrig mant.
For the jur... well, I always suggest to make one if you're a sin. PPE and skel work monsters are easy to kill, just go there and farm xD

PS: else, hodremlins in flee-build but, with now Santa poring card not coming out from boxes anymore, three of them might tame more time to acquire than 2x ppe and 1x skel worker lol.
