Veil — guide

the buff has two levels: Veil and Perfect Veil. A Champion under either of these buffs cannot be selected as the target of an enemy Champion's skill. Note: if all remaining Champions on your team have an active Veil or Perfect Veil effect, the enemy will no longer have any targeting restrictions. In the case of the basic Veil buff, the effect will be removed immediately if the Champion uses a skill that deals damage. Except for: Damage dealt by a skill that applies Veil; Passive damage; Damage that "does not count as a hit". At the same time, Perfect Veil is not affected, no matter what skills the Champion uses. Thus, it allows them to deal damage with impunity as long as the buff remains active.
