Tips and Tricks

The only way to win this game is to not play.

Proficiency

The stat gains from raising Proficiency start experiencing diminishing returns very quickly. At the moment, it's not a wise use of Draco to enhance any of your units past +10 at most. The stat gains at around +7 quickly drop and become very minimal. Since it's not easy to farm large amounts of Draco, enhancing units to high + amounts is difficult to recover from, with minimal gain.
