Innate: Upon taking fatal damage, Sion briefly becomes untargetable and enters a frenzy, restoring himself to 100% maximum health but losing 2 - 19 (based on level) every 0.25 seconds, increasing by 70% per subsequent tick.
Active:Sion bellows in the target direction, dealing magic damage to the first enemy hit, slowing them as well as having their armor reduced by 20% for 2.5 seconds.
70 / 105 / 140 / 175 / 210 (+ 40% AP)
Enhanced Magic Damage:
91 / 136.5 / 182 / 227.5 / 273 (+ 52% AP)
40 / 45 / 50 / 55 / 60%
If the target is a minion or non-epic monster, they are knocked back 775 units, dealing 30% increased damage to all enemies they pass through and slowing them by the same amount for 2.5 seconds. Projectile enemies stop upon colliding with terrain or reaching the end of their trajectory.
Active:Sion charges in the target direction for up to 8 seconds, during which he is pacified and unstoppable. Sion's trajectory updates itself toward the cursor over the duration, but his capacity to change directions is reduced.
Sion slams the ground around him upon colliding with an enemy champion, structure, terrain, charges for the full duration or re-activates Unstoppable Onslaught. Colliding with structures or terrain briefly stunsSion. If Sion stops directly in front of narrow terrain, he dashes over it.
The slam deals physical damage to nearby enemies and turrets, with the base damage increasing by 0% - 266.67% (based on charge time), and slows enemies for 3 seconds. Enemies directly hit by Sion are also pulled into him and stunned for 0.75 - 1.75 (based on charge time) seconds.
