Super piece for BLU; highest HP for the slot, so best for breaths. Also good for casting Frenetic Rip and Disseverment because there's no -DEX like Alky's.
Easily the best hand gear for Taru RNGs when using STR gear. Watch your damage increase with these, along with other STR pieces. Plus the 65 added HP is a huge plus. The lost AGI is really irrelevant at this point.
These are a great piece for pretty much all taru DD jobs (maybe not end game, but at least until you can get some dusk or homam...depending on your job and even then they are still good for WS's). If you use these with Creek M Clomps, you would have a phenomenal +100 HP! That could put your HP right up there with Mithra's and Humes at the same level.
