CC spells OR melee ability, but not both.
This discussion has occurred repeatedly in these forums. Basically:
- CC spells require a maxed or near-maxed charisma (so warforged is actually a weak option)
- Meleeing well enough to justify healing you requires a high strength
- Bards who don't want to be dead should want a high or high-ish constitution (not less than 14; 16 preferred; 18 if dwarf or warforged melee)
If you want to fit all three into a single build, the numbers just don't add up. We see the same story with feats: it's near-impossible to cram everything you want from both the casting side and the melee side, and then you still want Toughness.
I generally recommend that bards spec for melee: You'll still have CC songs, and you'll be better at soloing.
Note that the distinction I'm drawing applies only to
CC spells. Any bard CAN cram in good healing spells, and all bards should have good
CC songs.
Also note that you can have
some melee ability on a CC spell bard. I've been there, done that, though: "Okay, I buffed everyone up... and now I'm hitting Suulomades, but with such little force that I'd be more useful if I just stood back and healed." Or, "Oops, the orthon killed me. If only I'd built this character to survive longer and kill faster." Reaching that point typically requires dumping charisma down to 12 and pumping strength (and having a solid constitution). Maybe someone will come in and talk of their awesome Epic Dynastic Falcata or Elyd Edge build. I don't pretend to know the details of such builds. Heck, I can't even attest to their effectiveness, since I never observed one in action.
By the way, note that
spellsong vigor and sustaining song have serious bugs. I vaguely remember them simply not working on warforged.
