Crimson Cuisses: Less common than haidate, though with less purpose. However, anything requiring kiting with a pld really becomes 100x easier when the pld has these. Not game-breaking and not many things kited these days outside of various versions of King Behemoth, but they are still nice.
Defending Ring: Super-rare, super-sexy. Really not much to say.
Hecatomb Cap: Nothing comes close to this for WSing headgear. Moderately rare though not overly so.
Herald's Gaiters: Starting to lose rarity a bit but these can still make or break your linkshell in the mad rush to claim a mob, plus it allows for interesting strategies involving mages kiting or just keeping up with someone else like a kiting tank. Plus you can drop them and get 100 goldsmithing.
Ice Gauntlets: These are getting a rather COLD reception (LOLGETIT?!), thought they would do a bit better, at least due to the rarity and the interesting uses a pld can get out of them. Probably would rank higher if plds couldn't use Homam gear. Oh well, hopefully wave three's surprise item will do better, and yeah I already have one in mind.
Koenig Cuirass: Not much to say here really. The piece kinda speaks for itself stat-wise but there are nicer alternatives.
Novia Earring: Still quite rare, and pretty nice for a mage to macro on after burning whatever mp their earrings give them. So many great mage earring options though kinda bumps this down.
Sha'ir Manteel: Not so much rare anymore really, but the stats are really sexy and so is the actual item (on a female character!) so it's very easily recognizable. CAN be replaced with the "free" yigit body, but the other stats in addition to the casting down time on the manteel make it far superior.
Speed Belt: Would be a 10 if Swift Belt didn't exist. Can't justify giving it a 10 with that other option so much more readily available (even if the droprate sucks on swift belt if you're a mithra named Rappa).
Vivian Ring: Quite stupidly rare and coupled with a Serket Ring the absolute most +mp you can get in the ring slot. The rarity and the sheer "My mp is better than yours" power this thing possesses justifies the 9 rating to me.
