TERA guild leaders are being called on to register their clans for the new Crusade season that kicks off today and ends on June 21st. The TERA blog has been updated with a list of the Challenger League maps and Cutthroat League maps that gives a bit of a heads up for team preparation. Players not in a guild can join one by using the new Guild Finder.
Players not into the whole team PvP challenge thing can take part in Hard mode dungeons from the Secrets & Shadows update. Raid groups of either five or seven meeting the required minimum iLevels can work through both the Demokron Factory and the Shadow Sanguinary for a chance at Imperator equipment designs and crafting materials.
See more of the details on the TERA site.
