can you cast spells while inside a Prismatic Sphere?

[irdeggman]

Its protective - to keep your PC from getting hit with spells.

If inside the sphere you can still cast healing, buffing and other such spells. It is also large enough to protect some allies at the same time, say a cleric who can heal your PC.

You can cast invisibility too.

Dismiss the sphere and then leave undetected.

OK, so the general consensus is that no spells can pass through a Prismatic Sphere.

It is not a general consensus it is stated in the spell description itself. See above bolded text.

or they simply encase the sphere in another barrier.

Encase their sphere in your own and watch the fun when they try to exit......

I dont have PHBII, but doesn't mobile spellcasting not have any pre-reqs? Spring attack has dodge and mobility but mobile spellcasting doesn't, correct?

Sounds like a pretty good defensive feat if theres total cover anywhere near your caster, and has great application with touch/cone spells (although you don't dodge the AOO for moving away from your touch spell target).

It's in Complete Adventurer, not PHBII. It only requires 8 ranks in Concentration.
