Named item effects function similarly to unique effects, except that the effect is unique across any and all items which provide the named effect. Similar effects that do not share a name will stack, such as Quicksilver and 
Mikael's Crucible.

Quicksilver
Quicksilver is an active ability which removes all crowd control, damage over time and other debuffs. This effect has a 90 second base cooldown.
The following items grant Quicksilver:
Notes:
- Quicksilver will not remove persistent areas of effect.
- If Quicksilver removes Veigar's Event Horizon, the user will gain immunity to that instance of the skill.
- Quicksilver detaches the effect of Chum the Waters, prevents it from reattaching to the same champion, and removes the initial slow, but conveys no immunity to the damage, knockup/knockback, and AoE slow when the ability goes off at the end of the delay period.
- Quicksilver's interaction with leashed effects is somewhat complex, and it would appear that each is coded individually:
- Will entirely remove: Ethereal Chains, Soul Shackles, Death Sentence
- Will remove the crowd control: Nether Grasp, Hyper-Kinetic Position Reverser, Infinite Duress
- Secondary effects, such as damage over time, will continue until you "break the leash" (i.e. get out of range). Note that Hyper-Kinetic Position Reverser does not have a maximum leash range and the secondary effect can/will activate regardless of whether or not you are still under crowd control.
- Secondary effects, such as damage over time, will continue until you "break the leash" (i.e. get out of range). Note that
- Will not remove: Drain, Unspeakable Horror, Decrepify
- This includes any damage it applies and secondary effects.
- Will entirely remove:
Mikael's Crucible provides a similar effect, allowing you to remove crowd control from the target ally. Note that Mikael's Crucible does not remove damage over time or other debuffs, and it cannot be activated while unable to activate abilities (such as a silence).

Spellblade
- Spellblade may also refer to the item, Moonflair Spellblade, or the Spellsword mastery.
Spellblade causes your next basic attack to deal bonus damage after using an ability. ( 1.5 second cooldown )
The following items grant Spellblade:
- Sheen - Basic attack deals bonus Physical damage equal to your base attack damage.
- Trinity Force - Basic attack deals bonus Physical damage equal to 200% of your base attack damage.
- Lich Bane - Your basic attack deals bonus Magic damage equal to 75% of your base attack damage + 50% of your ability power.
- Iceborn Gauntlet - Basic attack deals bonus Physical damage equal to 125% of your base attack damage to surrounding enemies and creates a field for 3 seconds that slows enemies inside by 35%.
Notes:
- In the event you own multiple spellblade items, only one attack bonus applies, to which the order of priority is: Lich Bane, Trinity Force, Iceborn Gauntlet and Sheen.
- For channeled abilities (and such as Garen's Judgment), the buff effect timer will start at the beginning of the cast, not after the ability successfully cast off or ended. Leaving the player with less time to proc the effect.
- The area of effect slow is not considered part of the "Spellblade" effect, and is instead classified as Icy. If you own both Iceborn Gauntlet and a higher priority Spellblade item (i.e. Lich Bane and Trinity Force), you will trigger the higher priority's damage component while still triggering the area of effect slow.
- Abilities that apply on-hit effects such as Gangplank's Parrrley and Ezreal's Mystic Shot can trigger the damage and slow effects when the ability hits.
Spoils of War
Spoils of War: Basic melee attacks deal 200 bonus true damage to minions with less than 200 health. Whenever a minion is killed by Spoils of War, the wielder and the nearest allied champion are healed, and the ally gains gold equal to the kill.

Tenacity
- Main article: Crowd control#Reduction
Template:For Tenacity grants the user 35% crowd control reduction.
The following items grant Tenacity:
Notes:
- Crowd control reduction stacks multiplicatively.
- Until patch V1.0.0.118, Tenacity was an unnamed effect unique to Mercury's Treads. In the aforementioned patch, the effect was promoted into a champion statistic and three additional items were added: Cloak and Dagger, Eleisa's Miracle and Moonflair Spellblade. Tenacity from multiple sources did not stack, similar to Enhanced Movement. With the Season Three item overhaul and the introduction of named item effects, Tenacity was reverted to an item effect. In V3.01, all sources of crowd control reduction were changed to say "Tenacity" and Tenacity was reintroduced as a champion statistic.
- Tenacity DOES NOT reduce the strength of slows, only the duration.
- Until Season Three, Tenacity's in-game icon was the same as the icon used for Cho'Gath's Vorpal Spikes and Baron Nashor's passive. Between the introduction of season 3 changes and V3.01, it shared the same icon as the Tenacious mastery. As of V3.01, it no longer has an icon in the buff bar.
