Illuga is a straightforward character in Genshin Impact. He exists to buff Geo characters, especially when they deal Lunar-Crystallize DMG. Basically, he’s one of the best characters to include in Zibai teams in Genshin Impact. However, Illuga still needs a decent build to operate properly when supporting other Geo units. Here’s the best build for Illuga in Genshin Impact.

Illuga Best Weapons In Genshin Impact

Weapon	Why It’s Good
Favonius Lance	Illuga is a support unit in Genshin Impact who doesn’t depend on any weapon to activate their utility. For that, it’s better to go with supportive weapons that add more supportive mechanics to their gameplay, such as Favonius Lance. With Favonius Lance, Illuga gets the Energy Recharge he needs to keep casting his Elemental Burst, where most of his buffs come from. Additionally, the F2P 4-star Polearm will also allow Illuga to operate as a battery for the entire team, especially the Geo character he’s supporting.
Dragon’s Bane	If Illuga has enough Energy Recharge and the team can regain their energy without any delay, you can build Illuga with Dragon’s Bane in Genshin Impact. The 4-star weapon will grant Illuga around 221 Elemental Mastery. This is very important for Illuga since most of his kit scales with Elemental Mastery, especially his team buffs.

Illuga Best Artifacts In Genshin Impact

Artifact Set	Why It’s Good
Aubade of Morningstar and Moon	Illuga gets 80 Elemental Mastery from the 2-pc effect of Aubade of Morningstar and Moon. This is good for Illuga’s build in Genshin Impact. More importantly, when building Illuga with the Aubade of Morningstar and Moon set, he will increase the team’s Lunar reactions by up to 60%, which is an absurd buff for his team. The only condition Illuga has to fulfill is not being on the field, and that’s easy considering he’s a support unit that doesn’t need any field time.
