For a month after the event's release, it provided the owner with a 5% bonus experience boost. The 5% bonus experience boost stacked with the 3-6% boost from a Clan Avatar. If the owner also had a level of 96 Summoning, the Rhino also acted as a Beast of Burden, allowing the player to store items in their pet's inventory. The inventory space of the Black Royal Rhino was equal to that of the pack yak. The player could gain access to the Rhino's inventory in exchange for one pack yak pouch. Each pouch granted the owner 127 minutes of access to the Beast of Burden's inventory. The Corporeal Beast ignored the rhino, which made it very useful for carrying additional supplies.
