Notes and Explanations
After four ability uses, Mirror Talisman will be activated by the next spell Faeis casts. The effect of Mirror Talisman is similar to Sivir's Spell shield, or Nocturne's Shroud of Darkness. If any spells hit Faeis within the next 2 seconds, the effects of said spells are nullified. If Mirror Talisman nullifies a spell, Faeis will receive mana equal to 20% of mana missing. This can occur multiple times.
Stifle is a line skillshot. The first enemy it hits will have a "Stifled" debuff applied. The base duration of Stifled is 2 seconds. However, if the stifled enemy attempts to cast a spell or attack, the duration of Stifled will be increased by 0.5 seconds. While Stifled, all abilities and attacks the Stifled enemy attempts to perform will be cast on the Stifled enemy. This means that every time a Stifled enemy attempts to use a basic attack, they are in fact damaging themselves. If a Stifled enemy attempts to cast an ability with a target other than themselves, the ability will affect them instead of the intended target. This means that if a Stifled Ezreal attempted to cast Mystic Shot, the ability would simply target the Ezreal, damaging him instead of the intended target. If a Stifled Olaf activated Ragnarok, the effects of Stifle would end due to the crowd-control removal on Ragnarok, even though a Stifled enemy using an ability would normally increase the duration of Stifle.
Even if an enemy did not attack or cast during the duration of stifle, the ability would still be effective as a silence and blind.
