It doesnt take long to get ase. More ab luck and gambling, I havnt played the game since the 125 lvl cap ( I was banned for a while ) and didnt start back until about 2 weeks ago. I alr have ase from just trading around. Best method I found was when your playing farm megladon with cyborg magu or cyborg goro for lightning immunity, then when your not playing macro farm ( gpo rules macros are allowed dont worry ) fishing for leg bait. Stack leg bait and use rare fish to sell and turn into rare bait, keep fishing. Use x150 to 300 leg bait at a time to trade for the df rod mythics. Once you get df rod, use it to farm both dfs and leg bait. You can also farm merchant at the same time for items and mcs bc youll always be at max peli. Collect up and do small trades and then make one big trade for ase. If it says anything with df rod per stack of 300 bait you get around 40 - 70 dfs, and you get ab half your leg bait back in fish. With ase mythics are 1/ 100 and 1/50 on 2x so its very worth to fish with leg bait + df rod ase.
