Season 15 introduced the Slayer, a fast dual-blade assassin, and pushed the endgame into the Scorched Canyon and Crimson Icarus. Elite zones became a formal concept, and excellent socket necklaces plus third mastery earrings extended the accessory chase.
A high-speed melee character built around combo pressure, the Slayer launched with her own equipment line, gained a 4th class path and skill-enhancement tree in the same season, and immediately reshaped PvP tier lists.
The burning canyon arrived with a separate elite zone — a formalised 'harder copy' of the map with denser rewards, a structure every later season reused.
A blood-red retelling of the classic sky map, Crimson Icarus brought old-school atmosphere to modern level ranges, complete with a second Guardian boss tier.
Excellent socket necklaces and third-tier mastery earrings widened the accessory endgame, giving hunters two fresh best-in-slot targets.
