Upgrading
The Arctix System does not have character levels. It instead opts for an "a la carte" system of upgrading, giving the players more control and flexibility in creating the exact character they want. Players can purchase upgrades to stats of any kind, however, some stats have limitations. Players simply spend their Experience Points to purchase upgrades. Refer to the chart below for upgrade costs.
Traits
Players may upgrade base traits for 25,000 XP per point. This is meant to show that people can get smarter, stronger, more coordinated, etc. Upgrades in this manner are limited to 2 points from where a character started, however, per trait. So for example, a character who started at 4 Aptitude would be capped at upgrading to 6. Characters also are still maxed at 10, and cannot upgrade further.
Influence
Players may upgrade base influence for 15,000 XP per point. Players are not capped like they are with base traits, except that they cannot exceed the maximum score of 10 for any one Influence style. The reason for this is that a character may not have a high associated base trait, but may still be very adept at the particular style of influence. For example, a character of medium strength may still manage to be incredibly intimidating, or a player of low overall Aptitude might still become very skilled at reasoning or manipulating others.
