The Sauro Supply Base (commonly abbreviated as SSB) is a group instance for players of level 65 and above. The entrance was originally located in Danaria, but was later moved to Levinshor. The instance is very straightforward and is among the easiest of the 4.0 instances. Players may obtain fabled, eternal or, if lucky, mythic gear and accessories. There also is a chance to obtain a unique Danuar weapon and/or hat skin by killing the Grave Robber shugo inside the instance. Medal Boxes containing a Mithril or Ceramium medal may sometimes drop from the various bosses as well.
