When the whirlwind says you are "held suspended", does it mean Held as in Hold Person -- you can't move, can't attack. Or is that just some descriptive text and you can still attack and cast spells while in the whirlwind (I think it's clear that you can't move out of the whirlwind unless you can fly).
My group ruled held last night and got a TPK.
