Ethereal Weapon Item Guide - ARAM Mayhem On-Hit Formulas
Ethereal Weapon is an on-hit amplifier, not an automatic best pick. This guide covers AP, tank, physical and summon routes, item choices, champion fit and traps.
Current Patch Positioning
In ARAM Mayhem 16.11, 
Ethereal Weapon is a Gold augment built around mechanics, with about 50.1% global win rate and 0.3% pick rate. Its value comes from how well a champion kit, on-hit items and later augments amplify each other.
The core idea is not turning spells into basic attacks. It adds on-hit effects to damaging spells, so the payoff drops hard without triggerable items.
How To Judge The Trigger
Start with spell hit frequency, then check whether the item is actually an on-hit effect. Single-hit spells care about each hit, while damage-over-time and summons care more about interval, target count and positioning.
When paired with 
Mystic Punch, 
Dual Wield, 
Fan The Hammer, 
Tap Dancer and 
Master of Duality, high-frequency champions can stack item and augment value more easily. These are not mandatory every game, but they explain why the same Gold augment swings so much by champion.
Do not force your build around Ethereal Weapon if you lack on-hit items, miss often, or face heavy anti-heal and reflect pressure.
Four Item Formulas
| Route | Core items | Best condition | Watch out |
|---|---|---|---|
| AP | Lich Bane, Nashor's Tooth, Luden's Echo; Riftmaker for melee AP | High spell frequency with repeat hits | Do not give up spacing on poke champions |
| Tank | Heartsteel, Iceborn Gauntlet, Spirit Visage, Thornmail, Jak'Sho | You can stay in contact on the frontline | Pure durability is not enough without hits |
| Physical fighter | Trinity Force, Blade of the Ruined King, Black Cleaver, Hydra items, Stridebreaker, Terminus, Voltaic Cyclosword, Essence Reaver | Mixed spell and attack damage with repeat hits | Not every physical item is an on-hit item |
| Summons | Summon users such as Yorick, Zyra, Malzahar and Naafiri | Summons can reliably participate in hits | Still verify the current champion data |
Which Champions Should Prioritize It
In the current data, Hecarim, Kai'Sa, Ekko, Gwen and Katarina are high-fit samples worth watching first. Yorick, Zyra, Malzahar and Naafiri lean more toward summon-based mechanics.
The safest rule is champion first, items second. If the kit hits often and the items trigger on-hit effects, Ethereal Weapon is worth building around.
Common Traps
Do not judge only by global win rate. 50.1% means this is a mechanic augment that needs the right champion and items.
The listed items focus on on-hit value or reliable repeated hits. Do not add unverified passives to a fixed formula; if core items are unavailable, prefer direct damage, haste or durability augments.
FAQ
What does Ethereal Weapon trigger?
It adds on-hit effects to damaging spells, making items such as Lich Bane, Nashor's Tooth, Blade of the Ruined King and Heartsteel more relevant on the right champion.
Why is its global win rate not high?
At about 50.1% global win rate, it depends heavily on spell frequency, item route and enemy draft. Without good triggers, it is not a high-value pick by default.
Which champions fit it best?
Champions with high spell frequency, stable damage over time, summons or built-in on-hit value fit best. Ekko, Gwen, Kai'Sa, Yorick and Zyra are worth checking first.
