I was on Arkaz (Iron) with E on the weekend for Amazons and for a giggle I shot a Many Many Arrow (that normaly fires a bunch of magic missiles as well) and found that the caster LV had been set to 1. I tried on Ysgard as well and had the same result. I get a nice little feed back message from the spell hooking sayign the caster LV is set to 1. I can screen shot it if that helps.
I know they used to have a higher caster LV and the last time I used some on Avlis they did.
I havent tried any other sorts of amunition that casts spells on hit.
