Good day sir pls fix this po, I use this scroll makes me anoying. Some player get 50% but I use it, I can get 10% only freak lol. Pls fix this bug sir. Thanks

In fifth grade you will learn:

50% = 0.5

If your rate is 20, the valk will give:

0.5 x 20 = 10

Add 20 with the valk rate:

20 + 10 = 30

30% exactly how the game works. This is not a bug.
