each t2 lvl3 gives 144k plunder. if you have 10 forges you would get say 1.44mil plunder. divide that by two, which is 720k. and change k to mil. that leaves you with 720mil which is how much u need in allies for 10 forges. TO MAKE THINGS CLEAR~u need 720mil worth of allies to be maxed plunder when u have 10 forges
