Plans techs on the technology tree if you don't have anything you are particularly working towards to help your armies. Lure out the betrayer-traitor, yes-yes.īeeline to the various Monstrous/Virulent/etc. You raid and produce food (3 per raiding army), then when it rebels you kill the rebels for more food and also some experience for your general.
If you do have a lot of armies then set them to raid, even if it is in your own territory (in a province which doesn't produce much wealth).
Although it can be tempting to spam out a ton of cheap armies, each of those armies costs food so sometimes a bit of restraint can help. Battles are your main supply of food so make sure you have a constant source of them. Sack cities over and over to farm food from the poor garrison, let the enemy build armies and then ambush them and wipe them out (sack city with main army > ambush stance with main army > kill any army that tries to recruit or arrives to reinforce > sack city again with cheap slave army now it has a weak garrison and broken walls > Cheap slave army goes into raid stance > repeat from step 2).
