k. when you attack something successfully (eb or other players) you get a bonus to your plunder based upon your build and the amount of gold you have invested in allies. THE AMOUNT OF GOLD NOT THE NUMBER OF ALLIES. anyway. max plunder is based on your build. however you need gold invested in allies to make use of it. hire allies until the ally bonus stops going up when you hit the same target, at that point you are at max plunder for your current build.
going to add that max plunder is EXTREMELY important for growth. it will be your primary source of income. always make sure you are at max ally bonus. always.
Max plunder or MP. It's the allies bonus earned per hit on eb or opponent. To check for MP, it's simple At Full power, important. Hit eb/opponent once, only once, now this is important, write down or remember what yr allies bonus was. Then hit once more If this changes from what u noted, u are not at Max plunder. Now hire allies, repeat test until this number stays constant. Do this every time u build as well.
you don't have to be at full power. ally bonus is constant when hitting the same target. only your base plunder drops as your troop numbers go down.
