a few days ago i bought a lvl 85 rifle , then i used an enhancement lvl 75-99 card that gives +% hp because some tell me i have bad hp, and i wont be good, however i only got it to +5 with 5% hp , and its way too expensive for me to keep buying these cards because they cost 4-5m each card , and i may need like 30-40 of them to reach +10 , and i can't afford it,. Does anyone know how to remove enhancement so i can make my rifle back to level 0 so that i can use regular weapon upgrade cards ?
