To beat the Baron, if you choose the biological line, you need the skill disrupt and upgrade it fully. with it you can take out the barons focus, this makes him do that thing that damages him a ton for three turns.
when playing as Ellder there is a way to get three other people to help. right when you're about to enter the wood elves main place. you hire two spear men(because they are cheap, but they do a good job) and then make sure they survive the wood elf boss fight. after you kill the first boss the wood elf king comes in your group, and if your two spear men survive you get four to help you on your way and for me they stayed all the to the end...... useful tip: don't buy all the fighting moves because when you want to do a move, the guy will just do a move that you don't want...... For Ellder. first buy inverse whirl. then thrusting forward whirl. then, backflip thrust. and maybe knee stamp(i survive quiet easily with just these moves). then use the rest of the money you get for armor. one more thing, some moves need timing... hope this helps (anyone playing as Ellder).
for the legend badge,when it says you have to defeat the mayor without any training fights, does it mean you can't do any training fights, or does it mean you can't do any training fights when its time to fight the mayor. thats what i want to know.
