When determining the effects of your arcane school powers, you're considered 4 levels higher. This increases the effects of powers you have access to, but doesn't grant you powers at a lower level than normal. If you have an arcane school power that can be used multiple times per day, such as blinding ray, you gain a number of extra uses of that power equal half your tier (minimum 1). You must have the arcane school class feature to select this ability.
