Best Light Cones for Joy Trailblazer

Light Cone	Description
When She Decided to See	The best weapon for Yao Guai in HSR is the best light cone for Joy Trailblazer. It provides speed, energy, and energy recovery to the Trailblazer, as well as increased crit chance and crit damage for the entire team.
Joy Full of Blessings	Since Yao Guai’s light cone is not easy to obtain, you can choose the free weapon from the Virtual Universe – “Joy Full of Blessings”. It increases the attack power of EMC for personal damage, as well as increases the Joy meter for an ally when EMC buffs one of them.
Mushi’s Adventures	Another supporting F2P light cone. It increases the Joy meter of the owner, and after using a skill, all enemies receive additional Joy damage.
Tomorrow, Together	This event-rewarded weapon increases crit damage and provides a Joy buff for the entire team. However, the buff only lasts for one turn. Therefore, it’s good for a team with multiple Joy characters, but requires proper timing calculation for maximum effectiveness.

Best Relics for Joy Trailblazer

Relic Set	Description
Seer of Distant Lands	Increases speed and crit chance, as well as provides Joy damage to all allies.
Dusk Line Eagle	Extends EMC’s action by 25% after using the ultimate skill.
Hacker Space Messenger	If someone is already using “Seer of Distant Lands”, you can use “Messenger” to increase the team’s speed when applying the ultimate skill.

Planar Decoration Set	Description
Living Vonwak	The Trailblazer’s ultimate skill is the most important part of their set, giving crit damage to an ally and activating their Joy skill. Therefore, it’s worth focusing on increasing energy recovery to use the ultimate skill as often as possible. For this, you can use “Living Vonwak”, “Sunken Sea Mermaid”, or “Penaconia’s Dreamland”. Choose the one with the best secondary stats.
Broken Keel	If you want to neglect energy recovery, you can accumulate resistance effects to get crit damage for the entire team.
Speed Increase	You can also get more speed using “Calpagne’s Lantern Horn” and “Giant Tree of Sorrowful Thoughts”. The second effect is not suitable for Joy Trailblazer, but it provides speed as the first effect.
