I haven't been able to get any but the common bowcraft recipes, doing the bow making quests in Heartwood. It has been my understanding that any recipe has a chance of dropping from any of the crafting quests in Heartwood. But I have yet to see any recipes for tinkering, carpentry, or blacksmith. Early on I received an ash runic carpentry tool, and i also recieved an elven dresser deed (not the recipe to make elven dressers, but a ready-to-use deed). Are other recipes just extremely rare to get, or am I doing something wrong? I have been accepting quests for any type of bow, but I am turning down the quest for bolts and lap harps. Does not accepting those reduce/eliminate the chance of getting recipes?
