GS-3305 is Recommended if You Have Narumi
For the 5-Star weapon exchange in the "Weapon Exchange" tab, we recommend the GS-3305 if you have Narumi. Narumi is the only 5-Star standard character with two Elements and is a reliable Attacker who can deal high damage with his bonus against Core Exposed enemies. His performance can be improved by equipping his best-in-slot weapon, the GS-3305, making it a top recommendation.

If You Don't Have Narumi, Exchange for a Weapon You Don't Own
If you don't have Narumi, we recommend exchanging for a weapon you don't own yet.
Weapon Exchange Can Only Be Used Once a Month
You can only exchange for a total of one item per month in the Weapon Exchange. Once you make an exchange, you won't be able to use the Weapon Exchange again until the following month, so be careful not to choose the wrong weapon.
How to Obtain Refinement Crystals
Obtain by Dismantling 5-Star Weapons
Refinement Crystals can be obtained by dismantling 5-Star weapons. You will receive one Refinement Crystal for each 5-Star weapon you dismantle.
