At first level, you know 2 at wills, 1 encounter, and 1 daily power.
Let's say I'm a Tiefling Wizard.
I have an racial power of "Infernal Wrath" which is an encounter power. Wizards can also learn Burning Hands, Chill Strike, Force Orb, Icy Terrain, and Ray of Enfeeblement.
Does this mean I can only use one of the six? Or can I use Infernal Wrath, and another of the five for the class?
Similarly, there are 4 cantrips, and 5 at will spells. I get 2 at-will powers at first level, so does that mean I get the 4 cantrips and 2 of the 5? Or only 2 of the total 9.
