Summoning magic skill +10 is a great thing to have for macroing in on Blood Pacts and Elemental Siphon, definitely something SMNs should keep an eye out for.
Suitable replacement for Marduk's Jubbah for any BRD. This gives +1 extra CHR and +10 M.Acc for Lullaby, although Marduk's may be situationally better for a support BRD/WHM because of MP, Refresh, and Fast Cast.
Obviously having this for pulling/lullaby and Marduk's for other situations would be ideal, but this will serve a BRD better in far more situations than Marduk's would.
In response to Gira's comment and Kyaaaaaaaaaaaaaadaadayakda's subsequent retort, this is undeniably the best piece for a SCH's helix-type spells as INT is the numba one modifier for damage on it (because it possesses a very low base damage.) People are so quick to rate down on comments they don't fully understand. :( It is also notable that this is a great piece for a good RDM's enfeebling potency set (for slow and the like), however, you'll want to stick to your AF body for accuracy of course. Oh, and a few (about three) nuking geared RDMs can easily take down Ovni with some chainspelling and a bit of subsequent DoT kiting.
