2 Months without Botting & Paying is not possible. Even if you make 200k Uri a day.
Let's say you have 12 million Uri, you need ~7 to upgrade everything to lvl 16.
You get 1 Havoc from the Quest, still need 9. Let's say you get everything on the first try, and only need 1.000 Clicks to build it. So another million gone.
4 million left, you need Hercules, let's say you're lucky again, another million for 10 Hercs.
3 Million. = 2000 Keys. You need 45 LF4, so you'd have to get one out of every 40th box.
Okay, it's not impossible, but I'm confident you won't make it.
Considering the 200k/day already counts when you have a Phoenix with 0 lasers.
+ 40billion EP from quests only is unlikly. too
