Flins Showcase: Lunar-Charged Power
Flins is the latest Nod-Krai character to arrive and stands out as a Lunar-Charged DPS. With Prospector’s Shovel and Night of the Sky’s Unveiling artifact set, his Mini and Big Bursts deliver millions of damage when paired with another Nod-Krai ally like Aino or Ineffa.
At Constellation 0, his best F2P setup outputs around 1.3 million per rotation, making him one of the strongest F2P-friendly picks. His Triple Burst Playstyle—mixing both Mini and Big Bursts—offers strong long-term potential if built with enough Energy Recharge.
Best Teams and Weapons for Flins
Flins pairs best with Hydro enablers and another Electro support. His strongest team includes Aino, Ineffa, and Sucrose, but F2P alternatives like Ororon and Kuki also work well.
Weapon choices:
-
Prospector’s Shovel (F2P craftable, great balance)
-
Signature weapon (strongest option, lowers ER requirements)
-
Favonius Lance (smoother rotations, lower damage)
This makes Flins versatile, but still heavily reliant on Nod-Krai synergy to reach peak numbers.
