Dusk and Dawn strengthens Gwen's ability-and-attack rotation with Spellblade damage and an additional on-hit trigger, while Nashor's Tooth supplies Attack Speed and AP-scaling on-hit damage. Riftmaker increases damage and Omnivamp as combat continues, and Rabadon's Deathcap amplifies the AP ratios on her abilities and passive. Spellslinger's Shoes provide magic penetration, while Zhonya's Hourglass buys time after a deep engage. In the combo simulation, chaining abilities and attacks builds Conqueror quickly and gives the best extended-fight value.
