Odjoe, i think the ap bonus is totally random. I have my noble and the rogue both with ap bonus skill maxed at 10, and often i take 4 ap. It's matter of luck :-)
Earthbound, the game is very difficult at first. Try to get as many medals as you can, expecially those that give ap bonus. With time, the game will became easier. Unlock the noble and give him a bowgun, he's a real monster with his damage and accuracy bonus.
if you want to be rich, try a rogue in the party. I'm at day 212, harcore mode, with taunt i can obtain 20000 coin a day, without consider eggs and robbery. Rogue isn't a very good fighter, but give him a laser gun and he'll be of some help.
I'm trying to get the hardcore medals and badge, but i can't go over day 50. I have all medals. What do you think is the best setup to use in hardcore mode?
Please, could you give me some advice? what are the first things to do at first? What to buy, the best class to use...i can't pass the first 15 levels, just one time i reached lv 35 for pure luck with hunter and bowgun, but i can't find any good weapon. Any help? Thanks a lot!
