From everything we know, Ruan Mei is acombination of Asta and Tingyunwith some insane weakness-break capabilities sprinkled on top. Let’s take a look at her kit to understand how to play her optimally with the best Ruan Mei build.

Ruan Mei’s kit is stacked with buffs, her Skill giving a massive Damage and Weakness Break Efficiency buff. Her Ultimate furtherincreases All Type Resistance penetration for allieswhile delaying attacks from weakness broken enemies. Ruan Mei’s Talent also gives a Speed % increase to all allies and her Technique lets you enter battle by targeting enemy weakness, irrespective of ally damage type.

Ruan Mei’s ideal cycle rotation should be:

Skill » Normal Attack » Normal Attack » Skill » Normal Attack » Normal Attack

Her Ultimate lasts for two turns, so use it during a big damage cycle or when the enemy is close to a weakness break.

Ruan Mei is a very strong Support, but she can be even better with the correct Relics and Planar Ornaments. Here are the best Relics, Planar Ornaments, Sub, and Main stats for the Ruan Mei build.

Ruan Mei’s buffs are based on her allies’ stats, so her stats don’t affect most of her buffs. Since her kit is made for weakness breaks,the Thief of Shooting Meteor artifact set will be perfect for her. This artifact set will further increase her break effect, dealing additional damage with her Ultimate and regenerating energy with each break. You can also use the 4-piece Messenger Traversing Hackerspace for an additional 12% speed buff to all the allies.

For Planar Ornaments,2-piece Talia: Kingdom of Banditry fits her bestas it increases her break effect, directly affecting her Ultimate’s additional damage during the weakness break. You can also run a 2-piece Pan-Cosmic Commercial Enterprise to apply debuffs easily on enemies with high effect resistance.

For Relic stats, you must stack as much Break effect as possible. Also,make sure to add enough Speed to reach the high 145-speed requirementof the 2-piece Talia: Kingdom of Banditry. Other than that, stack HP%, Defense %, and Effect Resistance % to make her tank hits. As Break Effect damage is unaffected by Attack, Crit Rate, and Damage, there is no need to add offensive sub-stats.

There are a lot of good Light Cones that can work well on Ruan Mei. Let’s take a closer look at them:
