ROX - These Cards Will Change The Way You Build! [ENG] 

For starters, try a 2:1 ratio between P.Pen and P.Dmg Bonus. Example 200% P.Pen | 100% P.Dmg Bonus. As you progress more to higher level maps, you need to increase these 2 stats as well as the monsters will have higher stats.

@@SmoothifyPlays thank you! Will try the ratio.
