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.

First cast: Sion starts channeling, increasing the damage of Decimating Smash over the next 2 seconds. If Sion's channel is interrupted by crowd control, Decimating Smash will have a reduced cooldown.

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.

After 3 seconds, Soul Furnace can be recast to detonate the shield if it hasn't been destroyed, dealing 40 / 65 / 90 / 115 / 140 (+40% of ability power) (+10 / 11 / 12 / 13 / 14% of target's maximum health) magic damage to all nearby enemies. Bonus damage from the target's maximum health is capped at 400 against minions and monsters. The shield will detonate automatically if it persists for the full 6 seconds.
