Sion

Sion is a top lane tank built around crowd control that you can see coming but still struggles to avoid. He earns a defense rating of 9, which makes him a dependable frontliner: opponents generally read his next move correctly, and yet actually stopping him is a much harder job.

His laning rests on two abilities. Decimating Smash is a charged swing that launches and stuns everything inside it if he holds the charge long enough. Soul Furnace is a shield that explodes for magic damage and grants him permanent bonus maximum Health for each unit he kills. Because that Health keeps accumulating, Sion scales well into long games, and the later the match goes, the more difficult he is to pull out of a fight. Roar of the Slayer slows enemies and strips Armor, and it can send a minion flying into foes to extend its range.

The charge and the afterlife

Unstoppable Onslaught is the ability that shapes Sion in team fights. It is a charge across the map that gains speed as it goes, lets him change direction while airborne, and launches every enemy it hits, with the knock-up scaling to the distance he covered. A long-range ultimate followed by Decimating Smash works as a complete engage by itself. Even dying does not fully end his contribution, since Glory in Death gives him rapid healing attacks backed by Health that fades over time, so his body can still take a tower or secure a kill.

Sion suits players who like tank play that depends on macro: split-pushing without fear, starting fights from unexpected positions, and treating each death as a trade instead of a setback. The downside follows from the same design. Each key ability has a wind-up, so a quick opponent can dodge the swing or the charge whenever he telegraphs them carelessly.
