is there a link to what all the stats in the game do per say what is balance for a sorcerer....what exactly is crit rate i understand a crit chance but crit rate...what is impact factor and so on any help please

It does not really matter because all of the gear you get has the proper stats for your class.

Crit Rate is how hard your crit will hit i think and impact is the chance you have to knock someone down.

Impact = Knockdown chance.

Balance = Knockdown resistance.

Crit Rate = Crit Chance

Endurance aids your defense, it may also have other effects that I am not aware of.

Power aids your attack, it may also have other effects that I am not aware of.
