Max out CDR on Sion, max Q first no matter what, then E and level R whenever possible. Q is your bread and butter everywhere. In lane, it's a farming tool. If the enemy is stupid enough to stay in it while it's got the knock-up, use it immediately, auto once, yell at them with E, auto again, W and walk off their attempts at trading back. If they aren't that stupid, just use it to farm. You can basically go Full Nasus in lane and outscale anyone except
,
, or an actual
if he knows what he's doing. Use E whenever you can to harass or if the wave is bunched up and you can hit at least 3/4ths of it. Use W as a defensive button or when going for a Trade,** do not use it to clear.**
Remember that early on, your charge has a high cooldown, so save it either for a gank, when roaming, or if you need to get out of somewhere fast. As you get more CDR, you can be more liberal with it.
I usually get
and
to get 40% CDR. Frozen Heart is undervalued in Sion, it gives him great armor, 20% CDR,and an aura that's a giant middle finger to their AD carries and anyone that relies on auto attacks and makes you THAT MUCH MORE of a priority target (and as a tank, you want that.) However, it gives no health and that's not the best thing on a Sion. I haven't tested IBG or any other CDR item, so experiment and find out what works for you. Main point is try to hit your cap quickly, because the more your Q and Ult are up, the stronger you'll be.
synergizes with Sion stupidly well, but it's more of an item when your cooldowns are up, so keep in mind that a raw AD item MAY work better for you depending on the situation. I personally recommend
as an item if you think it'll be better, stealing back health works great on you though I haven't actually tested DD but it looks good imo.
In Teamfights you (usually) want to be the Initiator. If you see someone squishy step in front of the team, you fucking ult into that idiot and follow up with Q. If you lose the fight, it is your team's fault 4/5 times so don't blame yourself and move on.
Overall, your job is to Initiate and send all of their team to the hospital with Concussions or to the Graveyard. Any Further Questions?
