For new players or just want drops
Dont use any "force win", specially on multi wave quest.
You are missing a lot of drops in the long run.
Since the drop is based on "kill drop".
Ex, 3 mobs 3 waves, if you got "force win" you get the first 3 but not the remaining 6.
Just use atk and def multi, also np.
So far the "safe" number is 2 ~ 4 times, in reference of event boosts.
Level up and Ascend your unit for more atk and hp.
Ofc if they decided to look on your account then that's it.
I've been using x4 and np option for long now.
I've tried x5 to x16 and it's kinda obvious.
(I still dunno if fps hack actually works)
