This question already has an answer here:
I have a question that is giving me several problems, which emerged in an online land, a play by chat. In D&D an Antimagic Field says:
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.
Summoned creatures of any type and incorporeal undead wink out if they enter an antimagic field. They reappear in the same spot once the field goes away. Time spent winked out counts normally against the duration of the conjuration that is maintaining the creature. If you cast antimagic field in an area occupied by a summoned creature that has spell resistance, you must make a caster level check (1d20 + caster level) against the creature’s spell resistance to make it wink out. (The effects of instantaneous conjurations are not affected by an antimagic field because the conjuration itself is no longer in effect, only its result.)
Thus a summoned creature does not disappear but continues to exist even if it cannot appear in the area of the antimagical field and, therefore, the rounds continue to be counted. It can only reappear if the MFA moves or ceases and the duration of the summon has not ended.
How do Orb of fire / cold / acid / force / electricity / sound behave?
- do they cross the antimagic field without hitting the caster and proceed further?
- do they cancel as soon as they hit the antimagical field?
- hit and therefore penetrate the MFA injuring the caster?
My doubts arise because even though it is a Creation, and moreover Instantaneous, they are still a magical effect that is not permanent, unlike the Stone Wall, for example. They are not a "natural" energetic effect like a fire set by a Flaming Sphere (2nd level wizards / sorcerers), nor do they create a real puddle of acid in which one falls or lowers the temperature in the area. They are a magical attack, but not a magical effect like a crack in the ground, created with Earthquake, in which the caster would fall even if protected by AMF.
So how do these orb spells interact with an Antimagic Field?
