The Dark Ukanlos armor is exclusive to HR9. It is made of mainly Ukanlos materials as well as some Rajang, Lao Shan and Yama Tsukami materials. It is pretty hard to create because it needs 5 Ukanlos Stones (aka Ucamulbas Divine Jewels in MHP2G). It can be either obtained very quickly because the Ukanlos Stones are by far not as rare as other Hvnly items but if you have a lot of bad luck getting this armor can be really time consuming and annoying.
