A beastiary the way to go, you get 100 extra tropps - games design means they give you extra hit on osf. Also get more allies, attack someone - look at cash page, you get two sets of cash, your plunder & ally bonus. You get a LOT more from allies than you do from your own troops, you got to max that bonus - aim for allies equal in value to three times next land cost
Thanks all. My next land is 1.5B, so I should be shooting for 4.5B in allies ... wow, lotsa work to do. Again, thanks.
