Threats to Sion with this build

Show all
Threat Champion Notes
Bard Utility-centered supports like Bard, Soraka, Janna, and Nunu are pretty easy to bruise in lane.
Janna Janna's ultimate makes her a bit of a problem, but otherwise, not too tough to face.
Nunu Nunu tanking up later on may make him tougher to slap around, but otherwise he shouldn't be too much of a problem.

Video Guide/Notes

The following guide is made to accompany the following video:

Additional notes after the release of the video guide will be listed here:
- Changed the recommended ability rank order to better get effectiveness out of your W shield.
- Just made a minor change to the item build. With the removal of Zeke's Herald, I took that out of the utility options and replaced it with Frozen Mallet, an item that someone pointed out in the comments of the video guide. So if Vektordeformacio on Youtube sees this, let it be known that I liked your idea.

Pros / Cons


  • Not the strongest damage sponge early game compared to other tank supports
  • Damage is slightly lacking early due to utility masteries
  • Passive loses strength with a utility build
  • Can be kited when ability CD's are down
  • Can be disrupted pretty badly by abilities that reposition you from enemies
  • Somewhat easy to miss poke with Decimating Smash and Roar of the Slayer

Your passive, Glory in Death, is probably the least effective asset of Sion with this build. Basically just hit that Death Surge and go punch someone to either pick up kills you wouldn't have normally gotten or get some damage to assist your ADC in getting the kill before you stay dead.

Decimating Smash is your main tool for poking down opponents in lane and is what I personally get and rank up first. You basically charge this up to knock up opponents in a cone AOE in front of you. This provides good damage with good knock-ups, but it also comes in handy letting your ADC land more basic attacks on the enemies you knock up. This is why you want ADCs that can capitalize off of small amounts of hard CC, so your bot lane can make the most out of the Q poke you supply. And even they can walk out of the Q area, this ability can come in handy in controlling where the enemy is able to move when situations get hairy for them.

Soul Furnace is what I rank up second and has two aspects to it: It's active makes a shield based on your max health and can be detonated in order to supply damage that scales with the enemy's maximum health. This helps make you a better damage sponge in lane, as well as punishing tanky supports. Your passive component grants you extra maximum health based on how many enemies you kill, and this is why you get Relic Shield in order to maximize the amount of minion kills you can get as a support. (Your alternative way to rank this up is to fully rank it up after you put one extra rank into Decimating Smash and then fully rank up your Q.)

Roar of the Slayer is what I rank up last due to the level of damage it delivers per rank, as well as the increasing mana costs that go up along with it. This is a short skill shot that applies a slow and armor shred, but can be used on a minion to slam increased damage and the slowing effect into opponents at a longer distance. I would not recommend trying to get Relic Shield proc using the damage from this ability and would recommend poking enemies with this when the enemy minion wave is at full health so you won't steal any CS on accident.

Unstoppable Onslaught is Sion's famous ultimate ability in which you charge and slam into opponents with either a knock-up or a substantial AOE slow. In the laning phase, this comes in handy either providing a quick knock-up by slamming into your opponents point-blank or catching out enemies that are fleeing the fight. However, what you want to remember with charging people from a distance for team fighting is, one, try to avoid hitting the tank with your knock-up, and two, make sure you have a clear trajectory to hit someone with the CC.

The following start (With two biscuits) is what I recommend to get a stable start in the laning phase; the Relic Shield will provide extra utility by healing your lane partner and letting you generate some extra health with your, while the biscuits and Stealth Ward and Warding Totem help you get vision before you can obtain your Sightstone.

My standard protocol for playing support is to rush this and make sure your vision around bottom lane is covered and you're prepared for the enemy trying to either gank or get dragon.

This is basically your core build (Counting the Sightstone and Sweeping Lens from earlier to boost your utility with the Face of the Mountain's shield, maintain vision using your Sightstone and Sweeping Lens, and simply boosting your mobility.

Here are some options to upgrade your core: Additional health and wards for keeping vision can be supplied using the Ruby Sightstone upgrade, but I prefer getting Boots of Mobility to help your ability to roam. Alternatively, your Boots of Speed can be upgraded into Ninja Tabi, Mercury's Treads, and Boots of Swiftness depending on the enemy team composition.
(Also feel free to supplement your build with biscuits and Mana Potions with Vision Wards as needed.)

zeke's herald
For utility itemization, your least situational pick is Locket of the Iron Solari for going against AP-heavy or just bursty teams, but you also have Frozen Heart to work against enemy auto-attacking, zeke's herald to supplement auto-attack dependent allies, Ohmwrecker to tower dive like a boss, Zz'Rot Portal to increase your team's push.

Straight forward tank items you can use are Randuin's Omen to tank against AD damage, Banshee's Veil and Spirit Visage to work against AP opponents, and Warmog's Armor to generally increase your health pool. Thornmail can help a lot in dealing with auto-attack dependent enemies, but it's less advised compared to the other options.

My favorite offense item to get for this build is Iceborn Gauntlet, with it being the "complete package" between mana, armor, AP, along with buffing your CC and auto-attacks. Though it's not advised to get with this build, early offense can be supplied with Ravenous Hydra and Trinity Force is useful in supplying a general offense boost if Iceborn Gauntlet doesn't seem like the best option for you.

Additional upgrades after your full build is complete include the Homeguard enchantment for whatever boots you're using, Oracle's Lens for you to better control vision around the map, Elixir of Iron to boost your presence as the team tank, and my personal favorite elixir, Elixir of Ruin, for increased health and push.
