The skills that require a Codex can not be learnt, we've disabled them
The skills that require a normal book such as Kiss of the snake, Feather armagheddon, Winged shell and frost splash (do not take this one for CT) require you to open your New Horizons map from General Summer (he has a short questline that lets u enter Primal Map from Illusion Stone) and crafting the book from the Cauldron(inside Primal, Kirin town) by using Primordial Bloods (farmed in Hidden Dragon Den/ dailies)
