Clarity is an aura that grants mana regeneration to the caster and their allies. At levle 20, Clarity's mana regeneration is equivalent to the natural mana regeneration of 1886 mana. When the player has a large amount of life but little mana and needs both the regeneration and other mana-reserving skills, linking this with Arrogance Support might be a consideration. Beware the high reservation multiplier, however. For more information about auras in general, see aura. As Clarity reserves a flat amount of mana (whereas other Auras reserve a percentage), it can often be used at a low levle without overly compromising the mana available for active skills.
