The following items grant Quicksilver:
- 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.
- Will not remove: Drain, Unspeakable Horror, Decrepify
- This includes any damage it applies and secondary effects.

- 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.
- 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.
