There arent a whole lot out there. It's a rare drop during the Halloween event, and it was named improperly so some peeps that were getting it didnt even know what it was. Gives +2 taming. Only female chars can wear it.
You wont find much info about this on the website. Best you can do is search LeatherBustierArms to see how many are active. Item is all weird, called a vampire sash when clicked on in-game, called a concubines skirt on the website, and worn as a no-armor leather bustier.
My character identifies as someone who can wear that sash and if this game denies me my human rights, I’m suing.
It was called a vampires sash in game too. And you cannot wear it with polymorph. Here's the link: http://www.uorenaissance.com/itemdetails/BustierofDomination/1C0A/1 I thought it was just another concubines skirt and sold it away at 175k. Edit: Wait, it's not a sob story: managed to get another one after it. Never give up - but not easily gonna let go of it tho!
I think ppl who have them don't want to sell them at any price. It stacks with MOTW for a total of 105 taming. They are dyable (mine is purple, the original color was hideous), newbied but not blessed, and look exactly like a leather bustier. They give a few AR. I only put it on when taming tho, and wear normal armor otherwise. As expected with the UOR RNG, very often I can tame either a dragon or even a white wyrm in just 1-3 attempts, but I've failed 7-8x on a drake. A drake! The drop rate on these during Halloween seemed low. I know ppl who grinded (ground??) for weeks and didn't get one. I suspect the value might go down next Halloween if more drop. Mine is still called "a vampires sash". I don't know if I will rename it yet.
