This is a list of all available plans from Wrath of the Lich King:
This is a complete list of all blue and purple plans currently offered by WotLK. As time progresses I will be weeding out the common "trainable" plans as it will be assumed that all of our Blacksmiths have all trainable plans.
Please post here with any new plans you come across. I will make updates as I see them. Also, please add which character has the plans you'd like to add. Most people have more than one character and I have no idea which of your alts or main has which tradeskill. If there are any discrepancies (something that is on here that shouldn't be, vice versa, or anything that is incorrect) please let me know here or with a PM.
