I am having inconsistent result trying to apply slayer deeds to crafted bows. It seems all my bows are too poor in quality (say, a single crappy ruin bow), or too high in quality (exceptional/vanq). I've tried on a 20 or 30 different crafted bows bought/borrowed/stolen made from a range of wood in a range of qualities... What's the deal? Whenever I've used deeds on smithed weapons, they always go on. Is there a particular wood that's best suited for adding slayer deeds? Not trying to get max'd bows (though that would be nice), just some decent midrange ones I won't mind losing at champ spawns and such.
