Tighnari is the first 5-star Dendro character to make its debut in Genshin Impact. The Verdant Strider is a Forest Watcher who lives in the Avidya Forest. It's safe to assume that many will be pulling on his banner if you already have the character and are looking for the best Tighnari build, including the appropriate weapons and artifacts.
Best Weapons for Tighnari
Tighnari's signature bow, Hunters Path, is a no-brainer. It deals a lot of damage and has a high Crit Rate. It also has a 12% All Elemental DMG Bonus and increases the Charged Attack DMG by 160%.
Polar Star and Aqua Simulacra are two good weapons to consider if you are unable to get your hands on Hunters Path. Both deal significant damage and are quite viable on Tighnari. One underrated weapon that many may overlook is the Slingshot. It works superbly with Tighnari and is an excellent free-to-play option.
Best Artifacts for Tighnari
Tighnari's 4-Piece Gilded Dreams set increases Elemental Mastery and, depending on the Elemental type of each character in the active party, the 4-Piece Wanderers Troupe set may be better for you. Lastly, Deepwood Memories 2-Piece or 4-Piece sets increase Dendro element damage.
