Reset player level

Hi guys,

I used a hack to add 20,000 shards, but my player level up to 83. I didn't want to add XP, just shards.
Does anyone know of a hack to reset my player level?
I can't find any solution except to buy another key on another steam account.

Shards are already awarded by leveling up

fist of all 20k shards or Level 83 isn't much
u can get that by playing a month to two

and no, u can't reduce level
also u can't get shards without increasing the level
