Drop Rate. Accessories with 1% additional drop rate. You can get a total of 30% DR (5% per hime on a team of 6) and it basically moves your chance to get a Magna or Labros from about 35% to 65%. You might need to initially run a rainbow team (as you'll just stick six himes with DR accessories as opposed to getting it all from one element) and you'll suck for the raid. It's called leeching, but it'll speed up your farming by a lot. A lot of players do it.
