Baizhi Build

Shorekeeper’s signature weapon is not only amazing for her but also for any Rectifier support. Granting insane amounts of Energy Regen as its secondary stat, increasing the equipped character’s HP all the while providing additional Concerto Energy when casting your Ultimate is seriously valuable for any support that can equip the weapon. It additionally provides a team-wide ATK buff if the equipped character’s Resonance Skill is used and it provides healing, which makes it stand out as an amazing support weapon.

A utility-focused weapon prioritizing lightning-fast Concerto rotations over raw output with the ability to transform entire units' action priorities under the right circumstances. Not always a good choice but when implemented correctly makes all the difference. Also offers an immense amount of Energy Regen further accelerating rotations and supportive capabilities.

Best weapon choice if you don't have Concerto weapons available, acquired for free via Rinascita Exploration Quests, which gives a great amount of Energy Regen and an extra Healing Bonus boost upon casting Ultimate for higher sustain.

An easily accessible supportive option with a reasonable amount of Energy Regen. It also grants the unique ability to gain a sizable chunk of raw Resonance Energy once every 20 seconds. For most character's rotations in teams, this bonus will be ready every time it's their turn to switch-in, making this weapon a great choice for any character who doesn't need damage but needs their Ultimate fast and has trouble accessing it otherwise. The flat energy gain is more powerful the less energy the character and team they are a part of can generate. This weapon is preferred over certain 4-star Rectifier options that give Energy Regen such as Originite: Type V as the flat Energy boost from this weapon's passive is more effective at granting Resonance Energy.

Decent F2P craftable option that provides a lot of Energy Regen, some additional HP restore and some ATK% depending on your current HP situation. Little value beyond the Energy Regen and small ATK% boost.
