A: coz FS only had AOE in their bm2
Things you need:
1. A high level character that can enter Arcane trace. WA/FS/FA
2. A working AOE/NSD/NCD hacks etc.
3. and your level 1 character
For this boosting method, probably you will be level 50 in 1 hour.
If you are level 50 already you can enter chaos arena level 1.
I think 3-5 times in chaos arena will get you level 65.
If you are already lvl 65, you can now go to chaos arena lvl 2.
2-3 times will get you level 75 and you are now ready for ruina station.
Ruina station will get you level 100 at no time.
there is no need for special items, you just need etoku weapon in ****** ice and a lifesteal bracelets and earings. and you do the quest
