Level

== Unit level ==
The Unit Level increases the Unit's damage. We don't yet know how much, but hopefully it won't take long to procure some numbers.
idk the actual equation but this one is pretty close: 0.0038*level^{2}+1.69*level+lvl1 dmg
== Player level ==
Player Level is used to unlock many important features to accelerate progress. Trading, AFK Gem Farming, Raids, and even Codes are locked behind a level requirement.
Player Level, though inaccurate, is also used to judge someone's capabilities. For example, a level 20 typically has better units than a level 10.
