your attack an defense is your power in damage an your health also takes affect in your battles including fights, bosses an much more it all depends on what u wanna be do u prefer attack or do u like going all defense etc....an the xp it goes by your levels the more u level the bigger the exp get in average...i hope i am saying this correct...
I need more information. If i attack - i use only dmg stat or dmg+def. What give me health up (in battle i can heals thousand times = i not need big health) and otherr info. Exp from 1 attack is it based on dmg?
You need health to do more damage and to take more damage, do not ignore health. All the skill areas contribute in all areas of playing the game. Attack,defense,stamina health,energy ,and also clan,full clan makes a difference when fighting someone in your xp range who ever has more clan will fare better in battles. Players play all different builds for their character, you have to figure out what you want to do,if you choose all one way, you may regret it later, takes time to fix builds,IMO a balanced build for a new player might be a good thing to look at, there is a help section on the game page that may give you some info. If you click at the bottom of this page" CONTACT US" it will take you to a page look for KNOWLEDGEBASE in the header, click that look for the game you want info on , might be some useful info there for you.
There are several advantages to building your health as Linda said above. The bigger your health level the longer you can fight for as you stay alive longer. You can fight harder and the strength of your axe slaps also increase the higher your health. Another advantage is that your minimum health level that puts you in hospital and therefore immune from attacks (but not axe slaps) also increases with more health. So you enter hospital sooner away from your enemies at a higher minimum rate meaning it will take more and more axe slaps to kill you if that is what someone is trying to do.
