Restores 40% maximum mana to you and nearby allies.
Self, with AoE of 600
Clarity is a 'non-targeted' Summoner Spell. This spell instantly restores a portion of mana for yourself and all nearby allied champions.
Clarity is best taken in teams where most, if not all, champions are mana based. Usually this spell is taken by a mana-hungry champion that needs to compensate with low base mana/mana regen (eg. Malphite), or focuses on aggressive play by spamming their skills (eg. Ryze).
