So I just had a 1 on 1 battle, that lasted 5 round...which I thought was odd. Anyways it gave a good opportunity to look at numbers and maybe get an some idea of how battle works. Because in large battles all the numbers are averaged between troops. Some things I noticed are that in the first report it shows my workshop upgrades for my archer, but after round 1 they go away...I don't think this is due to endurance effects either. Also through out the whole battle his defense was higher than my attack. Anyways the archer ended up winning.
