Tenacity of the Millelith · GenGuru: Your guru for Genshin Impact

Set bonuses

2-piece: HP +20%
4-piece: When an Elemental Skill hits an opponent, the ATK of all nearby party members is increased by 20% and their Shield Strength is increased by 30% for 3s. This effect can be triggered once every 0.5s. This effect can still be triggered even when the character who is using this artifact set is not on the field.

Overview

Tenacity of the Millelith is a staple support set. The two-piece bonus adds HP, so it is a common half of a two-piece mix for HP-scaling characters. The four-piece bonus raises the ATK and Shield Strength of the whole party for a few seconds whenever the wearer's Elemental Skill hits an opponent, and it works from off the field.

To keep the buff up, the wearer needs a skill that hits often, such as a lingering field or a summon that attacks on its own. The ATK buff matters most for teams whose damage dealers scale on ATK. Characters whose skill hits only once in a while will drop the buff often.

Best for: Off-field supports whose Elemental Skill hits opponents often, especially in teams with ATK-scaling damage dealers.
