A nightmare for Sivir. Even if you block her Zenith Blade, she can still stun.

Bursty playstyle, self-sufficient ADC.

Champion Build Guide
I bet y'all didn't know Sivir had AP scaling.
- Spending 875 gold on
Pickaxe would grant 25 AD, or +27.5 damage added to
Boomerang Blade.
- Spending 850 gold on
Blasting Wand would grant 40 AP, or +20 damage added to
Boomerang Blade.
Is it safe to estimate that AD is around 33% better than AP? Not necessarily.
- The above calculations were made assuming
Boomerang Blade is at max rank, with 110% AD scaling. At level 1,
Boomerang Blade has only 70% AD scaling, making AP equally valuable in ranged match-ups. Only when the ability is maxed can AD be considered to be vastly superior.
- One benefit of building AP is in the cheap CDR and mana which aren't found in AD components. For example,
Lost Chapter would be comparable to buying
Caulfield's Warhammer and
Sapphire Crystal at a cheaper cost.
- Roughly one-third of the value of most completed AD items is in critical chance, life steal, lethality, or attack speed. None of these stats are beneficial for supporting. Only lethality benefits Q damage.
In short, AP easily competes with AD early in the game for this particular play style.






Ultimately, AP items are better for the true purpose behind Sivir's abilities:
...to control the speed of team fights. Even Sivir's passive

- AP items naturally have better options for area-of-effect utility.
Youmuu's Ghostblade is a strong pick-up for speed and
Boomerang Blade damage, but its speed boost is only applied to self and it's missing the +100% base mana regeneration that
Shurelya's Battlesong has.
- AD items are more expensive and offer less utility. That's because AD items are balanced around the possibility of auto-attacking, which support Sivir doesn't do a lot of. AP items are balanced around, well, abilities.
Frozen Mallet isn't applied on
Ricochet bounces and so
Rylai's Crystal Scepter does a better job of slowing enemies.




Sivir is one of the hardest counters to
Thresh,
Morgana, and
Pyke in existence.
Spell Shield sets Sivir apart from other ranged supports, allowing her to "body-block" linear skill shots in a similar fashion to Braum's
Unbreakable.
Boomerang Blade offers high-damage poke on a short cooldown. Its base damage + AD/AP scaling equals 184 at level 1 if it hits twice (in addition to
Scorch and
Summon Aery damage).
- Its range is comparable to that of artillery mages such as Vel'Koz and Xerath.
Mid-late game,
On The Hunt is only down for 47 seconds with 45% CDR.
On The Hunt with 45% CDR provides a semi-global presence to Sivir's team.
- Sivir can run bot or top to collect a minion wave, check brushes with Q, then rotate to a fight in mid lane with R.
Boomerang Blade has a monstrous collision radius, unlocking unique playstyles through itemization after 45% CDR.
- Easily apply Grievous Wounds with
Executioner's Calling.
- Assist the primary ADC with
Black Cleaver /
Zeke's Convergence.
- Control the movement of both teams with
Rylai's Crystal Scepter /
Glacial Augment items.
See the items section for more details.
One might argue that Sivir with
Essence Reaver and blue buff fulfills a similar role with 40% CDR and has much more damage with crit and attack speed.
Item Sequence






Neither
Boomerang Blade, nor
On The Hunt, nor
Spell Shield scale with attack speed or crit.
- Only one ability makes use of crit and attack speed, and that's the one we won't put a single point in until level 8:
Ricochet.
- Not even Sivir's passive
Fleet of Foot scales with attack speed or crit.
A traditional ADC build is extremely expensive, costing upwards of 10400 gold to be considered powerful.
- Support Sivir's full 6-item build costs 9650 gold and potentially less when
Frostfang's gold income is accounted for.
- With it, Sivir obtains vision control, on-demand speed, healing reduction, limitless poke, and a powerful team-fighting buff in
Zeke's Convergence.

Karma is the closest competitor among support champions as far as providing a team-wide burst of speed.

Spell Shield has a significantly shorter cooldown than
Black Shield.
Spell Shield is more difficult to use in terms of timing, but it's also easier in that it doesn't need to be targeted.
Black Shield has the advantage of being able to negate multiple abilities, but also none at all if her opponents deal enough magic damage to break the shield first.

Dark Binding provides crowd control which Sivir lacks and sometimes desperately needs.
Boomerang Blade provides great raw damage and higher accuracy, but
Dark Binding generally results in even greater total damage if it helps the ADC reach the target.
- The final verdict on this comparison is that
Dark Binding is superior, but only marginally.

On The Hunt is more flexible. Whereas both tools can be used to engage or disengage,
Soul Shackles is more conducive towards disengage situations and relatively difficult to use for engage.
On The Hunt has a wider reach, with an effect radius of 1000 compared to
Soul Shackles' 625. Morgana is often required to complete
Zhonya's Hourglass to effectively use her ultimate without dying. Sivir doesn't have this problem.
Sivir has no CC to disable fed assassins.
Take

Sivir is relatively weak to ganks.
She tends to push the lane, and her spell shield won't protect the ADC against spells from 3 enemies.


Spell Shield requires superhuman reaction time against many abilities.
1.5 second duration means you have to either predict or react, unlike


Spell Shield is a selfish tool by design.
It won't help allies against things which can't be body-blocked, such as Leona's



Teammates will typically be against you for playing Sivir support in any way, shape, or form.
There's no way around this one. League of Legends can bring out toxicity and distrust in people, and your AP Sivir support might just be the trigger to their short fuse. If you perform poorly, you will likely be reported (though nothing will happen if you simply play your game). Don't be surprised if your ADC intentionally feeds as soon as you die once. Every off-meta specialist has this burden.
Summon Aery and
Scorch add even more poke damage to Sivir's Q,
allowing her to accumulate enough kill pressure to compete with any traditional support in the bot lane.
Spellthief's Edge is an incredible starting item for Sivir.
It makes her Q stronger at level 1 than an ADC Sivir with Doran's Blade, as Q has a low AD scaling at level 1.
Item Sequence






Executioner's Calling has extreme synergy with
Boomerang Blade and
Ricochet.
The item inflicts Grievous Wounds on enemies via any physical damage.

What else could possibly compare? Varus Q? Caitlyn Q? Jinx R? Ashe's

Item Sequence


How often have you played against Soraka, Dr. Mundo, and Vladimir only to have your teammates build full AP and not a single


Glacial Augment opens an alternate speed manipulation play style for Sivir in cases where kill pressure from
Summon Aery may not be reliable.
Note: Alternate build path explanations will be coming in future revisions of this guide.
Sivir boils down to two principles.
- Don't miss Q. Predict which direction the enemy will dodge towards. Strafe horizontally in the same direction after throwing Q, applying trigonometry to hit your target twice. (video example)
- Don't mistime E. Sivir is an AD carry by design, and thus most of her usefulness is in staying alive and being a consistent threat. Her only form of crowd control is death. If you die first, you are vastly inferior to other champions in the support role.
She has very few intricacies, but they are worth utilizing.
- When clearing wards, use
Ricochet as an auto-attack reset.
- When being chased, throw Q to activate
Fleet of Foot's bonus speed.
- Use
On The Hunt to get closer to allies, as its effects last 8 seconds. This also helps you get into a more favorable position to tag multiple allies with
Shurelya's Battlesong.
- Don't be too reluctant to use
On The Hunt to speed up minions and help your team reach a tower faster after a victorious fight.

It becomes worthwhile to be aggressive with

LEVEL 4
You have two options:
In most games, you will want to invest a second point into E at level 4 to conserve mana. This is usually the case against melee supports who have high base health pools and dangerous high-cooldown abilities.
Don't forget to take W at level 8 if you choose this route.
Sometimes, you need extra damage to win a close fight. If your opponents' health pools and yours are equally low,

At the end of the day, Sivir isn't meant to be a consistently top-tier pick in the support role. If ![]() ![]() Sivir is deceptively challenging to play, requiring precise timing and a sharp instinct for reading the enemy's mind. Despite these difficulties, there is an aspect of elegance in its simplicity. Every time you successfully block a spell, you will feel rewarded. Every time you land a full-damage boomerang, you will feel powerful. If you enjoy chucking pizzas at your enemies, I'm sure you'll find some enjoyment playing AP Sivir support ;) |
