The Indra Shin armor is mainly made of G rank Shen Gaoren materials, as well as G Chameleos and Kushala Daora parts, and some bugs. It becomes available at HR7, but if soloing it can only be obtained at HR9. It's relatively easy to create compared to other armors of the same caliber, however the main problem will most likely be obtaining the 2 hvnly shells needed to complete this set.
