Advantage Points are awarded to a player every so often (usually in 2s) to be used to upgrade existing powers. Currently with the level cap at 40, players will receive at total of 36 Advantage Points throughout their characters 'life'.
Advantage Points can be spent to upgrade a power to the next level (at the cost of two points) or spend on upgrading a powers other abilities for added effects, such as giving it an area of effect or healing abilities. (cost of giving a power Advantages varies)
A Power can only ever have 5 Advantage Points spent on it, so if you wanted to spend two points on a level 1 Power to give it an area of effect damage ability, you could only spend 3 more points on it. You could upgrade it to level 2 for two more Advantage Points, but not to level 3 as it would cost two more points which would equate to six points total, one point over the maximum number of points you can spend on a power.
