Upgrading

__NOTOC__
Most Units can be upgraded to make them more powerful. A level increase usually implies a 10% boost in the Unit's stats, or a small improvement in other values like duration or cooldown. In the case of the card Shutdown, an upgrade increases the shutdown duration by 0.5 seconds.
