There are another few questions in my mind about Viking Clan... On the world bosses, does the player that deals the killing blow get any special rewards, or is it the same as everyone else? If your attack defense is exactly equal to your enemy's defense strength, does it say "You lose", "You win" or something else? At what levels does the amount of Exp required to level jump quite a lot?
i think it's at 1850 and 2500 that exp to level jumps up alot more but not 100% sure at level 4379 mine is 20741 / 131370
1. no special rewards. 2. it says Equal. however, in a fight, it's not only attack and defense that matters, the loadout as well as inventory. if you're asking about, having all of those equal, then it depends on the critical strike, which is random, so in the end there is always a winner and a loser. 3. at 1850, it doubles; at 2500, it's 2.5x and at 3000 it triples.
