Stridebreaker is a fun and viable item for Sion, and is my favorite Mythic Item for Darius. It eliminates their biggest weakness, which is being able to close gaps. You can use Stribreaker to cover extra ground before using Sion's Roar of the Slayer, or you can use it to get extra range to activate the second cast of your Soul Furnace. The item also grants Sion movement speed, which is another really nice stat to have no matter what portion of the game you're in. The biggest weakness of the item is that it won't grant you any resistances, which is arguably one of the most important stats on Sion, but you can still absolutely make it work! Try it out and see if you can use the active effeicantly.

Because Locket of the Iron Solari is now a Mythic Item, this is no longer a core item you should be building on Sion. If you're looking to play entirely around your team and you don't have a support already building this item, then it may be a decent pickup. Still, there are just better Mythics for him in Season 11. Locket of the Iron Solari (as far as I know) does NOT scale off your champions bonus HP anymore. It instead grants nearby allies increased armor and MR. Furthermore, if you plan on building this item, you must go with the build and rune setup I provided at the start of the guide. The payout isn't worth it anymore if you ask me.

This is a decent item to rush against an AD champion in lane, but is still overshadowed by how powerful Sunfire Aegis is. The item is a massive stat stick for Sion, which he absolutely loves. Since his passive already gives him bonus health, building straight resistances on him is extremely effective. The item gives Sion a whopping 100 bonus armor, an extra 10% Ablity Haste (another 10% from Glacial Shroud), and an additional 400 mana on top of the extra from glacial Shroud! The passive also reduced incoming damage up to a ca, so it's an extremely cost effective purchase against champions such as Tryndamere and Sett. Even if the enemy team isn't populated by many AA reliant champions, towards the late game, you at least have a go-to purchase to help itemize against the backline. For the price of 2700 G, this is one of the best items in the game for Sion. It's just too good at how it synergies with his kit. If you decide to go bruiser Sion to Split Push, or are playing around vision with AD Sion, selling your build to adapt this as a part of your core ensure you scale extremely well into the late game!

Spirit Visage is the second MR item you should be looking on purchasing in the event you happen to be paired against considerable amounts of AP. However, the item does have some situational use as a first item. The passive synergies well with champions such as Soraka and Nami, as they will have their healing bonuses increased by 30% when used on you. Rushing this item in lane can benefit Soraka's global ult! The problem with the item is that if your team doesn't have any healing to support the passive, it can be very gold inefficient, as Sion has no way of healing himself with his abilities. The item does enhance your health regen and the amount you're healed by potions, but I personally don't think that's enough to warrant you rushing the item if your team still doesn't have considerable healing! It's a good item to purchase if the enemy team is flooded with magic damage, but it's an item designed for bruisers who heal damage from Conqueror and in extended trades.

This item is pretty self-explanatory for the most part, however, the most important thing to keep in mind is when to build it! Remember, since Sion's passive gives him bonus health from actively killing creeps, he can unlock the Warmog's Heart passive relatively quickly! This passive gives Sion an insane amount of health regeneration outside of combat, if he has a minimum of 3000 health. This passive is strong enough to the point where the only factor determining how long you can stay outside of base is your mana. Purchasing Warmog's Armor as your second item is EXTREMELY effective, but ONLY if the first item you completed happens to give you health. This is because, although Sion's passive provides him with bonus health, it is not enough to unlock the Warmog's Heart passive if it is the first item which grants you health. Towards the late game, the item serves as an excellent way for Sion to expand his already massive health pool!

As late game begins to approach, you might notice your relevance in terms of damage output begin to fall off. Sion is in no means a bad late game champion, however, it will become increasingly difficult to outduel late game carries with a full damage or bruiser build. When this point in the game arrives, purchasing Gargoyle Stoneplate is one of the best purchases you could possibly consider! The item gives you 40 armor and 40 MR, which might sound quite lackluster on paper, but the primary reason we purchase this item is for its passive and active ability during teamfights. When three or more enemies surround you, Sion gains an additional 40 resistances of each type, granting Sion a total of 80 resistances of each type from a single item! Furthermore, when activated when three or more people surround him, the item DOUBLES Sions health momentarily, at the cost of dealing reduced damage. Furthermore, the bonus health you get from it also applies to the Locket of the Iron Solari Shield, so you should be looking to complete it earlier in the game if you plan on building around that item. If not, just complete this as a final item, or when you think your damage is beginning to fall off. It's value is just too good.

If you're looking to play Bruiser Sion who is also capable of split pushing, Titanic Hydra is the item you're going to want to get! Once you're done itemizing against your opponent in lane, rushing this item provides Sion with an incredible amount of utility in and outside of lane. It gives Sion a decent amount of AD and health, and its build path is exceptionally good. Rushing an early Tiamat allows Sion to have solid waveclear without having to waste mana. But the main reason we would want to purchase it is for its AA reset and its passive, cleaving damage in an AoE around the target we hit for bonus physical damage scaling off our HP. This means by sitting in a side lane all game, killing lane minions, and stacking HP off our passive, the item will just get stronger as we play the game! The Titanic Hydra build path helps Sion with his already insane waveclear, and split pushing all game will allow you to scale insanely well into late team fights! When your damage and relevance begins to fall off, and champions begin to contest your split push, sell your bruiser items, and purchase the Locket of the Iron Solari and Gargoyle Stoneplate to maximize your playstyle around your carries!

If you're interested in stacking a lot of armor against an all AD team, Iceborn Gauntlet is going to be the item you want to build! Just like Frozen Heart, the item gives Sion everything he wants to function as a champion; 65 Armor, 20% CDR, and 500 Mana is nothing to scoff at all. The primary reason this remains a situational item is because the item is mostly outclassed by Frozen Heart unless you begin stacking armor, which is when the passive from Iceborn Gauntlet becomes extremely effective. The passive creates an AoE field which briefly slows enemies trapped inside of it, which increases in size based on Sion's bonus armor. If you find yourself in a situation where you're forced to stack large amounts of armor against the enemy, you should highly consider this item! If not, just build the Frozen Heart if you plan on front line tanking.

Randuin's Omen is most certainly not an item you are going to find yourself building ever game, but it does have very powerful situational use. The build path for it is already rather friendly, allowing you to rush the item against specific matchups. The item gives Sion 70 armor and 400 health, but the main reason we purchase it is because of its passive, which negates 20% of all damage from critical strike basic attacks. Because of this passive, Randuin's Omen should always be rushed if you find yourself having trouble against champions such as Tryndamere and Yasuo. In fact, this item should always be rushed if you find yourself playing against a Yasuo in lane. This is because Yasuo's critical strike chance is doubled in exchange for reduced critical strike damage, so reducing his critical strike damage by another 20% can be detrimental for him being able to push you out of lane. If the enemy AD carry in the bot lane manages to get fed, and you need a reliable item to prevent them from completely taking over the game, this is also a very valuable item to incorporate as part of your build.

Among the other two MR items mentioned for tanks, Abyssal Mask is honestly the worst for Sion! It's in no way inherently bad, it's just the other two are able to synergize with his kit much effectively without the added effort. The two parts passives give Sion mana restoration based on how much damage he's taken, while nearby enemies take increased magic damage. By the time the item is actually completed, Sion should be at high enough level where the majority of his mana issues are negligible. Even if it's gained from what Sion already should be doing, tanking damage, the value is still not worth what you have to pay. The increased magic damage to nearby enemies is nice, especially since two of Sion's abilities deal magic damage, but you have to understand that Sion's viability does not come from his magic damage, it comes from him being a frontline threat who can function as a bruiser! Pick the item up if you're stacking full MR against an all AP team, or if your team has AP bruisers who can increase their damage from the item's passive. IF not, just stick to the other two items mentioned previously.

Sterak's Gage can be an amazing item to purchase on Bruiser or tank Sion! The item mostly depends on how well you value the passive and whether or not the enemy team has the appropriate burst to activate it. The first part of the passive grants Sion boonus AD equal to 50% of his base AD, which is always nice to have, no matter what build you decide to go with him. However, the primary reason we purchase the item is because of the second passive, Sterak's Fury. This passive grants Sion a shield which sales off 75% of his bonus health after taking a certain amount of burst damage. This means that all the HP you stack from your passive and will contribute to the shield's strength, which is capable of reaching absurd numbers in the late game! The best part about it, is that it includes the bonus health from activating Gargoyle Stoneplate, which effectively doubles the strength of the shield, if it activates while you have the bonus health.

If you're looking for the biggest troll item in this game for Sion which is 100% not troll, this is the item for him. I honestly don't know what Riot was thinking when reworking the build path to include the Aegis of the Legion, but the added resistances make this item absolutely broken. The main reason we are able to build it is because on top of the resistances it grants us, the passive mitigates 30% of all damage as DoT, allowing you to negate absurd amounts of burst damage. It scales incredibly well into the late game, where it'll prevent you from getting absolutely shredded in teamfights. The only real reason I consider this a situational item, is because of the price tag tacked on to it. 3600 G is a lot of farm you have to generate to purchase the item, so unless you're ahead in lane or managed to pick up kills in early game team fights, I would just hold off on purchasing it until the late game.

I would definitely consider Trinity Force one of the more situational items to build on Sion. However, there's a reason why it's considered one of the best items in the game. If you plan on split pushing in a side lane, manage to get fed in lane, or plan on playing AD/ Bruiser Sion, this item is an absolute must to pick up. Sion utilizes every passive and ever stat this item has to offer, where the only downside to it is the high price tag of 3733 G you're force to shell out. The passives grant Sion increased MS and increased damage on the next AA after using an ability, which turns him into a turret shredding machine. Honestly? This item will be down to personal preference. If you like the playstyle it has to offer, and want to spend your time farming side lanes, test it out for yourself and see if you can get any use out of it!
