Alex wanted the battlemage class in real life, as it was the class he had in the ancient world and knew best about it, but he didn't want to acquire it the common way of first becoming a swordsman and then a mage and then learning to wield them in harmony to get the third rank promotion as a battlemage.
However, to avoid the long route and get the class on the first Rank promotion, he needed to have a hundred points of stats in strength and mana and above sixty points in every other stat to be eligible to acquire the battlemage class from the start.
A hundred points of any stat was extremely challenging to reach before the first Rank promotion, and to do so in a short period of twenty days like he wanted was even harder.
Alex held confidence in reaching those stats without even needing to awaken his elemental physique because all his stats were already above sixty points each, and they continued to increase, albeit at a very slow pace.
