I will be the first to admit that I'm no expert on imbuing, but something has me stumped. I tried doing a search here to see if this has already been posted, but didn't find anything. My apologies if it's already been discussed and I just missed it! Why do you need to use Enchanted Essence (and citrine) to imbue Luck on a throwing weapon, but you use Magical Residue to imbue Luck on armor and other types of weapons (including gargoyle style weapons in the other warrior skills)? Is there some kind of explanation for this that I've overlooked, or is this a bug?
