the Plus 1's r better than most things..
its goes like this. Ares > Drachen finger gauntlets +1 O.o
its ur best bet if upgrade theses to +1 untill u find a good salvage ls
DRG's have better options to TP in than this.
Battle Gloves, for example, should be worn until Spiked Finger Gauntlets, or Tarasque Mitts +1. Those should get replaced by Dusk Gloves anyways.
Overall, yes DEX+3 is nice, but ACC+3 or ATK+12 is better. (Not to mention Haste.)
