Gen Narumi is the only permanent five star dual-attribute attacker. Since both of his attributes are physical, he can efficiently chip away at enemies with physical resistance. Combined with his bonus damage against exposed cores, he’s a highly reliable attacker.

Wait Until After You’ve Finished Early Gacha Pulls
The best time to use your 5-Star exchange ticket is after you’ve spent the free gacha tickets from the start and completed your rerolls. At that point, choose a character role your roster is missing.

In General, New Characters Are Recommended
It’s usually best to use your 5 Star exchange ticket on a character you don’t already have. In later stages of the game, you’ll need two full parties to progress, so in the early game it’s more important to expand your roster.
