Collei is a 4-star Dendro unit released alongside Tighnari in Genshin Impact Version 3.0. She’s one of our first playable Dendro units in the game, and even though she’s featured as a 4-star on the current first phase of the event banner, players can get her for free by completing the Graven Innocence Event.
Collei’s Best Artifacts in Genshin Impact
Collei’s kit, like any Dendro support, will require enough energy recharge for a decent uptime on her elemental burst. As a Dendro unit, she will also need a healthy amount of EM and maybe a Dendro-damage main stat artifact for reliable and consistent Dendro damage. With that in mind, here are her best artifact sets.
Deepwood Memories
This set gives her bonus Dendro DMG bonus as its 2-piece effect and as its 4-piece effect- it shreds enemy Dendro resistance to boost your Dendro damage and your Dendro reactions damage. Since this set works off-field, this is the best overall set for Collei.
Noblesse Oblige
This set is excellent on Collei if you are building Quicken teams, as most of the damage and reactions in that team will come from your electro teammates. The set buffs her elemental burst damage and gives bonus ATK% to her teammates.
Instructor
A really good 4-star artifact option- this set gives Collei bonus EM as its 2-piece effect. As a 4-piece effect, Collei will buff her teammates with bonus EM every 8 seconds every time she procs elemental reactions. This set situationally also outperforms the Noblesse set, so it isn’t to be taken lightly.
For players who haven’t leveled up their Traveler and mainly focus on building other party members, Collie will be the only guaranteed Dendro unit, and it helps that she fills a support role. Even though her Dendro application isn’t as consistent as the Dendro Traveler’s, with the right build and proper investment, she can become decent Dendro support for your adventures in Sumeru.
