How to find spell and item IDs
The easiest way is to use and addon like IdTip, ElvUI or All The Things
(If you use All the Things you cna enable ids in ATT Settings->Interface->Information and then enable "itemID" and "spellID")
Alternatively you can get the ids from Wowhead - just look up then item or spell and it's ID is in the URL!
