Let me explain melee attack damage
Your
attack damage is directly porportional to your HP. So if your max
attack is 4 dmg, you will do 4 dmg when your HP is full..
If
you are at 1/2 hp, you will only do 2 dmg. Get it? , Melees make sure
and keep your HP up. This does not apply for magic users.
The same applies for monster damage. The lower their HP, the lower their damage.
XP in a Nutshell
As
you fight and kill more and more monsters, you will gain more and more
experience. When you die to a monster, you lose experience (as
well as any gold you may have been carrying). Dying can be costly and
time consuming, so try not to do it too often ;).
Oh yeah, you also lose xp when you die in the mines. Keep that in mind.
Special Note: When you are level 2, that doesn't mean you should fight level 2 monsters.
Depending on your Skill levels and items, at about level 10
you may want to venture out and test the water. Don't be discouraged if you die a lot in the beginning.
But then again, don't be a damned fool about it either. =P
