Stat wise, I'd suggest Imaginary Damage Boost on the sphere, and either attack or energy regen on the link rope. If you're using Echoes of the Coffin as your Light Cone, its speed buffing effect might help you do that, but otherwise Musketeer should help you reach it. The Space-Sealing Station set buffs attack by 12%, and a further 12% if you hit 120 speed. Planar Ornaments: Space-Sealing Station (Two-pieces equipped).

As mentioned, you also want to make sure Luocha is over 120 speed for that extra attack buff. In terms of main relic stats, attack is a good shout, but you could also go with an Outgoing Healing on your chest. While Wastelander of Banditry Desert is an option for that 10% Imaginary damage boost, I think Musketeer is better for an attack buff, since that extra speed will help Luocha meet the secondary condition of the Space-Sealing Station ornament I'm recommending, granting him a further 12% attack. Musketeer of the Wild Wheat increases attack by 12% for two-pieces and buffs speed by 6% and basic attack damage by 10% for four-pieces. While the Passerby of Wandering Cloud set buffs Outgoing Healing, it's better to simply increase Luocha's attack, as this gives him both better healing and damage. Relics: Musketeer of Wild Wheat (Four-pieces equipped).
