Discussion about Dungeon (Dark Elves).

Regarding the main parameters. The percentage increase (30-10-45-15) can be influenced by artifacts (i.e., if you significantly increase one of the parameters using artifacts, then when the hero levels up, this parameter will be increased more often).
Therefore, for a Warlock warrior at level 20, having 20+ attack and 10 defense is not a problem (this has been repeatedly verified in practice).
