Can it be done or does movement interrupt spell casting I can't seem to find the answer in the knowledge base. I found where it says you can move while charging up a powerful attack but nothing on spells.

From what we've seen there are mostly instants, but a bit of channeled/cast things. Think they said you could cast while moving, but not channel?

From what I have seen, the casted spells are very very rare (one for nightblade, one for sorcerer) so yea, you can cast while bunnyhopping around

Looks like you can, very cool, although I did like those big crazy charge-up spells in Skyrim that slowed you down.
