Narukami's Wisdom, Narukami's Joy, Narukami's Affection, and Narukami's Valor are weapon upgrade materials used to upgrade Inazuma's weapons. Currently, four weapons use the Narukami power-up line: Hamayumi, Katsuragikiri Nagamasa, Predator, and Thundering Pulse.
You can grow these materials at the Flowing Sand Court, which is located near the Grand Narukami Shrine. The domain does not require a special unlocking method, just locate it on the mini-map and unlock it as you would a normal domain. (You can get there by heading north of the Sakura sacred tree waypoint.)
Narukami's Wisdom materials are available on the following days:
- Tuesday
- Friday
- Sunday
The domain recommends bringing the characters Geo and Cryo, as enemies are susceptible to Geo attacks. Geo characters are especially useful, as their shield strength is increased by 40% (good for Zhongli and Noelle, but should work with other shields like Diona or Xinyan as well). Additionally, elemental fragments generated by geographic reactions unleash a shockwave that deals area damage to nearby enemies.
The fight of domination consists of several Hilichurls, Electro Slime and Mitachurls with crackling axes. You don't really need a Cryo character for this fight, but a Geo character with shields should help you absorb much of the damage. Combat is fairly straightforward, with not too tough enemies.
There are four difficulty levels that unlock as your adventure rank increases. The higher the difficulty you challenge, the better your rewards will be. You need 20 Original Resins to claim your reward on each race.
