Anti magic zone qestions?

[Mathius]

Can you cast a spell while in a AMZ?

If not what about disjunction?

If I use spellbane can I teleport into a AMZ?

No, no and no.

It prevents the functioning of any spells within it's confines, which covers your first 2 questions. Spellbane (set to antimagic field presumably) only suppresses spells that are within its range around you, so it can't suppress the antimagic field you want to teleport to. Though you could just teleport right next to it...

[Mathius]

An invisible barrier surrounds you and moves with you. The space within this barrier is impervious to most magical effects, including spells, spell-like abilities, and supernatural abilities. Likewise, it prevents the functioning of any magic items or spells within its confines.

An antimagic field suppresses any spell or magical effect used within, brought into, or cast into the area, but does not dispel it. Time spent within an antimagic field counts against the suppressed spell's duration.

It does not say you can not cast.

What If I target outside the zone or use an effect AMZ can not deal with?
