I tried that once on my sister's 2nd phone a long time ago. You can have dozens of uniques, can unlock all chest and upgrades that you can virtually make your character invincible in just hours of tinkering.
At first I enjoyed it because all I need is already there but the happiness has faded away so quickly. I abandoned it altogether because I feel no sense of achievement.
There was no challenge at all that it became SO MUCH BORING π.
I returned to my original account cause I cannot be happy by becoming a cheater.
Becoming strong is achievable without cheats like one of the top 10 in ranking in the arena.
