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.

Second cast: Sion smashes his axe into the ground, dealing somewhere between a minimum of 30 / 50 / 70 / 90 / 110 (+0.45 / 0.525 / 0.6 / 0.675 / 0.75 per attack damage) and a maximum of 70 / 135 / 200 / 265 / 330 (+1.35 / 1.5 / 1.65 / 1.8 / 1.95 per attack damage) physical damage in an area in front of himself - depending on channel time - and briefly slowing enemies hit. If he charges Decimating Smash for at least 1 second, enemies hit will also be knocked up for a minimum of 1.25 seconds, up to 2.25 seconds if Decimating Smash is fully channeled.
