Is this book plot cliche? If so how can I make it better?

Have you ever read "The Night Angel Trilogy" by Brent Weeks? If you haven't then I'll warn you your idea of stones and activators is extremely close to his idea of the ka'kari and the ka'karifer so you might want to change it to something other than stones, eg weapons or talismans. The hand mark thing is a bit like eragon so you might want to move the burn location eg to the heart. Other than that I think you have actually came out of the usual LOTR esq rut that it's so easy to fall into when writing a fantasy novel. The idea itself is good, just watch out for plots that have already got some of your ideas in and just twist them slightly. Hope I get to read the full story at some point. Hope this helps =D
