Also Oriana+Maokai, harrass all day err day without any problems thanks to thier huge range
Edit:
DPS Sion, build suggestions, GO!
- Start with doran's ring as you'll go OOM otherwise. First level is always on the stun on Sion.
- Next, leveling order is Cannibalize > Enrage > Death's Caress > Mean Look
- Executioner's Calling is an
excellent item for early game, as you use both the lifesteal and crits, and you can also use it's active on champs with heals. oh, and this costs almost nothing.
- Boots of choice, but not Berserker's Greaves. They just aren't worth it.
- More crits. Enrage gives loads of damage so you don't need to worry about that. Get 2 zeals, maybe 2 critcloaks, and then upgrade into phantom dancers.
- Infinity Edge.
- Atma's Impaler, as you have loads of HP because of Enrage and farming. Armor is very welcomed as well.
- Last item of choice, you may want lifesteal or mana stuff, but whichever suits you the most is the best pick.
Runes: ARpen Red & Quints, mana regen rest. These are what I use, at least.
Gameplay: Farm early game. Just farm. Don't harass with shield, save it for killing minions/saving yourself. Harass with stun and 2 quick attacks: if one crits, you just took at least 1/4 of enemy's hp. Congrats.
Save ulti for a fight or if you have troubles staying in lane, lifesteal off of minions. If enemies harass with range, go heal yourself from jungle (small golems or wolves)
Once you have at least 1 phantom dancer, you may consider PvP. Before that, no. Farm.
Late game with full build goes by tanking 1 vs 4 and lifestealing them. And getting a triplekill before the 4th enemy escapes.
For skins: Barbarian Sion
ONLY FOR DPS, Hextech Sion
ONLY FOR AP .
TL;DR: DPS Sion is very dependant on gold and thus needs a ton of farming to work. This means AP Sion > DPS Sion when it is about early/mid game.
When farmed, DPS Sion is unbeatable unless stunned/blinded/cannot attack.
