Passive：Glory in Death
Sion turns berserk once he loses all his health, gaining a full life bar
along with significant attack damage, attack speed and lifesteal as he bleeds
out. His abilities are all replaced by Death Surge, which gives him a huge
but brief movement speed boost. Sion dies once his health drains out.
Q:Decimating Smash
Sion plants his feet, rooting himself as he winds up and swings his axe in a
broad area before him. Decimating Smash deals increasing damage the longer it
’s charged, and once it’s at least half-charged, knocks up all caught
enemies when unleashed.
W:Soul Furnace
Passive: Sion earns bonus max health every time he kills a unit.
Active: Sion creates a bloody shield around him. If the shield stays intact
for its duration, it explodes, dealing magic damage to all nearby enemies.
Sion can also detonate the shield early by reactivating the ability.
E:Roar of the Slayer
Sion bellows in a target direction, damaging, slowing and shredding the armor
of the first enemy struck. If Roar of the Slayer hits an enemy minion or
jungle monster, Sion’s scream also knocks them back a significant distance.
The thrown minion or monster then damages and slows all other enemy units
hit.
R:Unstoppable Onsaught
Sion starts charging in a target direction, building up speed as he moves and
trampling enemy minions along his path. He can cancel his charge early, at
which point he slams the ground, dealing area of effect damage to all nearby
enemies. Otherwise, Sion charges an extremely long distance, only stopping
once he hits an enemy champion, wall, or reaches the end of his charge. If
Sion charges into an enemy champion, he knocks them up and deals area of
effect damage; if he hits a wall, Sion stuns himself briefly and deals area
of effect damage around him.
