Wanwan: Best build, Counters

Tiger Pace

Enemy heroes hit by Wanwan's attacks will have their weaknesses and positions exposed for 5s. When hitting an enemy's weakness, Wanwan deals 67 (+3*Hero Level) extra True Damage and increases their damage taken from her subsequent attacks by 10% for 5s.
Wanwan can dash a short distance after each arrow fired from her Basic Attack. The dash speed scales with her Attack Speed.

Swallow’s Path

CD: 12 Mana Cost: 85

Wanwan throws a Fire Swallow in the target direction, triggering Tiger Pace while dealing 120 (+40% Total Physical Attack) Physical Damage to enemies in its path. The Fire Swallow then turns into 3 rotating Swallow Daggers. After a short delay, these Swallow Daggers will fly back to Wanwan one after another, dealing 120 (+40% Total Physical Attack) Physical Damage to enemies on their way back and slowing them by 30% for 1.5s. Enemies hit twice by the Swallow Daggers will be immobilized for 0.5s.

Needles in Flowers

CD: 24 Mana Cost: 125

Wanwan removes all debuffs on herself and triggers Tiger Pace. Meanwhile, she shoots Deadly Needles in all directions, dealing 150 (+60% Total Physical Attack) Physical Damage to enemies hit.

Crossbow of Tang

Wanwan leaps into the air and becomes untargetable, firing arrows at the target enemy hero for 2.5s in rapid succession, dealing 60 (+35% Total Physical Attack) Physical Damage per arrow. If the target is killed during this attack, Wanwan will switch to another enemy hero in her attack range, gain 30% Attack Speed, and extend the skill duration by 1s (this effect can trigger up to 3 times). Wanwan can trigger Tiger Pace upon killing an enemy and at the end of the duration.
Crossbow of Tang can only be cast on enemy heroes with all their weaknesses hit and Wanwan gains 100% Movement Speed during the duration. This damage is regarded as Basic Attack damage, and the firing rate scales with Wanwan's Attack Speed.
