You should upgrade a little bit of everything. Make sure that the weapons of the archidons and swordwraths are fully upgraded. Do one or two each upgrade on the miners. Do all but one level on all the spearton upgrades. One the magikill do one or two for each upgrade. You shouldn't do any for the giant. Do one on each for the castle. But you could do two on the automatic income. Good luck! :)
