Been fooling around with my artificer character, who has Eldritch Fusillade Expertise, which among other things states the following:
"Draw or stow a wand and load crossbow as free action."
Now a little known fact (PHB 242) about wands in 4e is that you can craft them with any encounter or encounter-utility spell, turning them into a magic item daily use ability.
Let's say I created a wand with the wizard spell "Shield", which is an immediate interrupt. In order to use the wand as an interrupt, would I need to be holding it in my hand when attacked, or could I have it in my character's pack or holster and draw it as part of the immediate interrupt "round"?
To use a magic item's power do you have to be "Wielding" it or just have it on your person?
