Weapon upgrades aren't a problem. Vanilla RTW, in fact, came packaged with the Pantheon of Artemis, which gives a +5 upgrade to missile weapons by itself! People have been puzzling over that, and I've heard conflicting reports of the extra +2's effect. You could get pretty close to a +9 XP bonus in standard 1.2 (+7 with a Pantheon of Epona and any +2 unit), but you couldn't reach it, and I haven't seen any mods that let you.

As for farming_level, RTR has a temple that increases it, I think. Maybe I'll check to see if it's working, and what happens if you go over five total.
