States of tutors? Approx 2% of your tb, is added to your stats during battle, both offensive and defensive battles, also know as an invisible bonus. So in other words, your tutors help make you slightly stronger. However, the downside to this, is that for every 100kcs tb you have, your plunder drops by 30k And in the means of plunder, for every 1kcs you're, you need roughly 15mil in tutor value to be at max plunder, so if you're 100kcs, it would be: 100 x 15,000,000= 1.5b in tutor value
