Upon taking fatal damage, Sion briefly becomes invulnerable then enters a frenzy, restoring himself to full health but begins to drain (1 + level) health for the first tick and increasing by (0.7 + (0.7 x level)) health per tick. Sion can freely move and attack during this time, gaining 100% lifesteal, attacking at 1.75 attack speed and dealing 10% of his target's maximum health as on-hit physical damage (capped at 75 bonus damage against monsters).

Additionally, Sion gains the ability to cast Death Surge using any learned ability.
