I heard something about having like 3x or 4x your stats in tutor bonus for max plunder But then again, ask someone with more experience?
Multiply your kcs by 15m for max plunder.. You're 120kcs, so 120 x 15 = 1800mil, or 1.8b. Spend 1.8b in tutes to make max plunder If you're still confused, check out the plunder guide in the strategy section of forums..
