Fresh Air Catalyst is a highly mobile dps roamer that provides excellent boon support to the team. Catalyst is hard carried by Fresh Air in the Air traitline. Fresh Air not only buffs damage but allows you to constantly swap into Air Attunement to refresh the buff, generate near-permanent Superspeed, and drop your Deploy Jade Sphere off cooldown.
Your ‘Hard CC’ comes from Gale and Comet . Gale is especially good in mirrors against other Catalysts since it is unblockable and ignores Fortified Earth and Final Shielding . Keep in mind that all your CC skills can be reset to extend lockdowns. This is especially useful with double Gale to secure kills in a teamfight.
Catalyst benefits from both the high base damage of Scepter and the absurd boon output of your Jade Spheres. A Fresh Air Catalyst can stack 25 Might, Quickness, Fury, and Superspeed easily in a teamfight and SHARE boons to its allies.
Dragon's Tooth is an an powerful AOE damage skill that will follow your target around like the Sword of Damocles and snipe them regardless of line of sight. Combined with Phoenix and Fresh Air, it can annihilate entire teams, especially when you reset everything with Elemental Celerity.
