Casting spells inside a Prismastic Sphere?

[Elurindel]

Can the creator of a Prismatic Sphere cast spells from inside the sphere at targets outside of it, or does he have to pop out in order to attack?

[Swooper]

By RAW, I'd say no. It says nothing about not blocking spells cast from the inside, and it's based on Prismatic Wall which works both ways.

[Elurindel]

Just as I thought. Thanks for the help

And unfortunately there's no easy way to walk out, cast a spell, and walk back in in the same turn.

The easiest way is probably to get a fly speed and take Flyby Attack. Then you can pop out of the top of your Sphere, cast a spell, and pop back in, just for bonus cool points.

Note that an oppponent can still ready an action to attack you as soon as you show your face.

Of course there's an easy way. Take Mobile Spellcasting from C. Adventurer. If you make the 20 + spell level conc check, you get to move and cast at the same time as a standard action. Then, you still have a move action left. Neat huh?

[Elurindel]

What about take the five foot step out, cast, move back in?

Can't five-foot-step same turn as a movement.

[Elurindel]

Hmm, that complicates things. At least now I know.

[Worira]

And knowing is half the battle.

[Elurindel]

But what's the other half?

[Collin152]

But what's the other half?

Combat.
Yep. Combat.

Right. Forgot about that one.

If you walk through your own sphere, is your familiar subject to its effects?

What if you ride through on a mount or a Phantom Steed?

[holywhippet]

I'd assume you could cast touch based spells and have your familiar deliver them on the outside. Of course, anything strong enough to warrent you casting prismatic sphere is likely strong enough to eat your familiar for lunch.
