[Magic] Magic Items, Magery and Missile Spells

I'm using Missile Spells, but this applies to any spell that uses the caster's level of Magery.



OK, Missile Spells allow you to put your Magery Level in energy for the first 3 seconds/turns. If casting from a Magic Item does this use your Magery or that of the person who created it?



If not yours I'm guessing this is recorded as part of the items stats? I only ask because before there's never been a mention of this sort of thing in Magic Item stat blocks
