My first magic item [PEACH]

[Fualkner Asiniti]

I made this for a campaign with my friends a while ago. I need help with caster level and pricing.

Ok, here it is:

Petals of Destruction:
This item appears to be a regular rose. when the correct word is spoken, the petals unwind, and they become a +2 spiked chain. this change is a free action, though you may make the change only once a round. Also, by shaking the chain (a full round action.) four petals fly out and magically seem to track the target. they are the equivelent of a magic missle spell (CL 8 ) and may be directed at any target. the petals take an additional round to regrow on the chain, and until then, the user takes -1 on all damage rolls.

Ok, I need help classifying this, just because its been bothering me. and feel free to comment. Thanks.

Shouldn't it use thorns instead of petals? "Every rose has its thorns..."

I just though that using petals was more original... maybe it's a lily. yeah, it's a lily. ;D
