You'll get a third legend eventually. It is recommended to keep them for Legends that do not have farmable characters you'd be feeding them for sockets, because otherwise you'll be wasting that same character EXP bonus. Of course now that we have Forbidden Tomes, their EXP will be wasted instead... still, I wouldn't use it on easy to farm raid bosses like Z. I got mine to 50s or so just from all the copies I fed him, and I think I'll get him to ~70 by the time I am done with him. If I was starting out I'd say use it on Eneru, since he is hard to farm and you want him MAX ASAP for so many raids.
