==FAQ==
How do you apply enhancements and limitations to a leveled trait?
:You must always compute the total point value of your trait (by multiplying the cost per level by the number of levels you want to buy) before applying the enhancements and limitations cost modifications.
:For example, say wizard A wants to buy 5 Extra Fatigues (at 3 points per level), with the limitation Spellcasting Only (a -10% limitation). The total price is 3 points/level * 5 levels = 15 points, – 1.5 for the limitation = 13.5 points rounded up to 14 points.
In this case you don't multiply since it doesn't apply to all levels.
