Magus focus spell Runic Impression in its description, it says
"Your unarmed attacks or weapon gain the benefits of a weapon rune you choose when you cast this spell: corrosive, flaming, frost, ghost touch, returning, shock, or thundering. If you cast runic impression on a weapon, this spell ends if you cease holding the weapon."
so I want to give my thrown weapon a [returning] rune, wishing that it can flies to me after my Strike.
But I also find that "this spell ends if you cease holding the weapon", so I throw a weapon to strike, when it leaves my hand, the spell ends and the rune disappear, my thrown weapon will never come back. ("cease" is even not the free action "Release",so it can be used more widely)
Is there some errata about it? Or it's intentionally designed to be stupid?
