I have recently been leveling a warforged wizard and have some questions about some of the specifics of the Pale Master PrE. Hopefully some of the experienced players who have tried out their characters on the test servers will be able to answer this stuff. This will be my first caster character so forgive me if some of my questions are noobish.

1) Does Quicken alter the 6 second cooldown of Necrotic Touch?
2) Will any of the metamagic feats cause Necrotic Touch to cost spell points?
3) Is Heighten necessary for the Necrotic Touch or does the level of the spell increase as you increase in wizard levels?
