Is there any real advantage of delivering the eleventh and twelfth tome of knowledge?

Question

It looks like the eleventh tome gives you the possibility to trade a red lantern for a dragon statue and the twelfth a red piece of cloth for a dragon throne.

It seems to me that the utility of the delivery of tome of knowledge end in tome number ten that give access to Zao palace, is it right to assume that? Is there an achievement or something that I am missing that makes it worth spending those two extra tomes to deliver all twelve?

Answer 1

Other than unlocking those cool looking furniture items you will unlock the possibility to deliver extra tomes for 5000xp each day, in my personal opinion i don't think it is worth to deliver more than 12 but i like the furniture items, up to you if you would rather sell the tomes or just see a more complete quest log, there's no achievement for that either way though.
