Three things that I have seen over and over again on posts, but I have never seen an "Offical" words about.
Can a wizard copy spells in his spell book that are above his level?
If you have a Flaming Long Bow +1 (+2 total enhancement bonus) and a Icy Burst Arrow +1 (+3 total enhancement bonus). What is making contact with the creature? Is is a +1 Flaming Arrow, a +1 Icy Burst Arrow, or a +1 Flaming Icy Burst Arrow.
If you have a quiver that turns arrows from normal arrows into magic arrows (using the spell Deadeye arrow or magic weapon); is it a wondrous item, a magic weapon, or is it a wand?
