Is WoL the only one able to master/handle all the classes at once?

While I can't speak for the lore book entries, for the lvl80 drk quest journal entries, certain passages written by Fray only appear if you are wearing the dark knight soul crystal. If you take it off, those passages disappear.

Ah, I see. Garland tools only shows one conditional entry in the journal section and considering the majority of it seems written with Fray's influence anyway, I didn't think much of it.
