RIFT is almost two years old? It's true, and Trion is marking the occasion with another incarnation of the Carnival of the Ascended. This year's addition features Tier 3 planar attunement, the PvP Wheel of Fate warfront, and the usual collection and quest festivities along with their associated rewards.
