Combining spells efficiently

[Saladrex]

Hello all,

This can be a thread where people describe nice spell combinations or tactics, not only for attack, but for defense and for "buddy improvement" too.
But I will start with a question:
- A Sorcerer who cast Prismatic Sphere and then casts Anti-Magic Field. As for the PS description he can go through the sphere without suffering its effects. As for the AMF description, it doesn't affect the PS (and both are 10' radius. AMF is the entire sphere, and PS is only a semi-sphere shell).
But what happens in the situation above? The main points are:
- By the time AMF is cast, does it become operational? (Remember that there is the Prismatic Sphere already in place) From my point of view: yes, and the caster gets a PS "shell" with an AMF "core"
- When the caster moves, AMF moves along, and PS is static.
- The AMF can't affect PS, but does it crosses the PS shell if the centers are not in the same place? (ie: the caster has moved but not crossed the PS shell)
- What happens when the caster crosses the PS? From my point of view: AMF functions normally, except on the PS "shell", where all the effects still affect the trespassers.

Hmm, no replies? Maybe I was confusing writing this one... any experienced player to help me on this one?

The description for Prismatic Sphere states that it's the same as Prismatic Wall save for it's shape.

From the SRD, Prismatic Wall:

The wall can be destroyed, color by color, in consecutive order, by various magical effects; however, the first must be brought down before the second can be affected, and so on. A rod of cancellation or a Mordenkainen’s disjunction spell destroys a prismatic wall, but an antimagic field fails to penetrate it.

So the Anti-Magic Field would be active inside the Prismatic Sphere but could not extend outside of it, regardless of where they are centered.

As the AMF cannot penetrate the PS, the effects of the PS remain unaffected, and will still affect any creatures (save the caster) crossing through.

Hope this answers most of your questions.
