• When stacking health, build a Sunfire item over Overlord’s Bloodmail or Riftmaker.³
• Sion’s health stacking helps build the exponential health scaling from the Stackosaurus and Heartsteel quest combination.⁴
• Sion is good against some immobile tanks.⁵
• Circle of Death can benefit Sion occasionally; it benefits champions with large health pools or strong self-healing.⁶
• Go For The Head can work on Sion as an AD tank who auto-attacks without building crit; Icathia’s Fall alongside Vulnerability can make its damage more dangerous to enemy bruisers and tanks.⁷

• When Sion dies, Glory in Death restores him to maximum health, which rapidly decays, and reduces incoming healing. He can cast Death Surge, move, and basic attack; his attacks become very rapid, gain life steal, and deal bonus physical damage based on the target’s maximum health.⁸⁹¹⁰ Patch unknown
• Death Surge gives Sion a brief burst of movement speed.¹¹ Patch unknown
• With Circle of Death, Warmog’s, and other healing increases, standing still can burn the nearest enemy for 500+ damage per Warmog’s tick.¹²

In patch 26.19, Sion’s Glory in Death stacks per round changed from 133 to 111.¹⁴
