The Harmony Mystery Box

I can't believe that i spent 500US$ when i first play this game

Damn, you know how to take my money, GGG. Great job.

hello, again

Hi,

I had purchase Annihilator Pack recently, and decided to buy the lightbringer envi effect, done, and few minutes or so after that i check my mtx and there was a Harmony box, dont remember purchasing it nor coins deducted on that amount.

Was it free or randomly given whenever we made any purchases?

Thanks
