Shyvana

Strengths

Shyvana's abilities all benefit from attacking units. As a result, Attack Speed items are more valuable on her than most champions.
Flame Breath is great to level-up against difficult lane opponents.
Burnout is an ideal choice for jungling. Monsters will be hit by the full duration, and the speed boost improves her ganking potential.

Passive · Scalemail — Takedowns on enemy champions, large minions, and large monsters grant Shyvana Scalemail stacks, improving her defenses.
Q · Emberstrike — Shyvana's next attack strikes both the target and the surrounding area. This Ability can be recast. While in Dragon Form, it gains an additional recast, dealing massive damage to a single target.
W · Inferno Aegis — Shyvana gains a shield, movement speed, and after a short delay, the area around her detonates. While in Dragon Form, the explosion will heal her if it strikes an enemy champion.
E · Molten Burst — Shyvana launches a fireball that explodes upon striking a large target and slows them. In Dragon Form, it passes through and explodes upon striking large enemies, leaving behind a trail of fire.
Ultimate · Dragon's Descent — Shyvana transforms into a Dragon and leaps forward causing enemies along her path to flee. While in Dragon form she becomes larger and her basic abilities are empowered.

A suggested 5-lane lineup built around Shyvana, based on hero partnerships and role synergy — not win rate.
