Elemental Fletcher

Elemental Fletcher: You spend a moment to speak the activation words for the spell imbuing your fletching tools with a magic aura. For an hour you have the ability to imbue arrows that you make with any element of your choice (acid, cold, fire, lightning, poison, or thunder). After you have created your arrows they will hold this element until they hit a target or until you die. The target if hit will take 2d8 of which ever element you had chosen to imbue your arrows with. Once imbued with the magic from this spell the arrows will have glyphs inscribed across them and the fletching will release a harmless visual effect of whichever element is imbued in the arrow.  If this spell is cast at higher levels add 1d8 per level higher than 1st.
