Overall

Unyielding Wing

Sion builds momentum through Gale Blessing — a stacking buff earned by dealing damage that increases his damage, energy recovery, shield gain, and attack speed all at once. Once stacks reach a threshold, he enters the Windwalker state with massive accuracy and pierce bonuses. Control effects strip stacks, but he can regain them by resisting controls. His ultimate generates vortices that orbit enemies dealing continuous damage; nearby vortices merge into stronger tornados. Normal attacks that hit vortices or tornados split into multiple spinning blades that target separate enemies. His blade throws steal energy from targets and cripple their energy recovery and shield generation. A wind shield provides heavy protection against ranged attacks, tripling its blocking power against long-range damage while deflecting most projectiles.

Skills

Wingstorm Barrage

Ultimate

Generates vortices that orbit enemy heroes dealing continuous Dragonspeak Damage. Nearby vortices merge into stronger tornados. Normal attacks hitting vortices or tornados split into spinning blades that target separate enemies. Extra vortices are generated based on Gale Blessing stacks.

Gale’s Breath

Passive

Each hit builds a stack of Gale Blessing, up to 100. Each stack increases damage dealt, energy recovery, and shield gains. Control effects strip a portion of stacks; resisting control instead grants stacks. At high stacks, enters Windwalker state with massive Accuracy and Physical Pierce bonuses, and normal attacks throw extra spinning blades.

Whirling Blades

Active

Throws spinning blades that steal energy from enemies and reduce their energy recovery and shield gain briefly. Effective at shutting down enemy sustain and ultimate cycling.

Skyward Protection

Active

Creates a Wind Shield that blocks damage, with triple effectiveness against ranged attacks. While shielded, gains Tenacity and Dragonspeak Resist. Has a high chance to dodge and deflect projectile attacks while active. Normal attacks throw extra splitting blades while the shield holds.

Signature Item

Cyclone Arc

Each Gale Blessing stack increases Sion's attack speed, up to a cap. Control effects only strip a reduced portion of stacks, and resisting control grants stacks. Sion starts battle with initial Gale Blessing stacks. At a lower threshold, enters Windwalker and normal attacks throw extra spinning blades.

Generates 4 vortices to attack enemies for 6 seconds. Each vortex will whirl around enemy heroes one after another based on their positioning. As each vortex hovers on its target, it deals 140% Dragonspeak Damage per second to the target and nearby enemies. As the vortices begin to circulate, they can merge with other nearby vortices to form tornados, which are more powerful and deal 300% Dragonspeak Damage per second.
