Recommended Main Weapons

Berzerker faces strong competition for its mainhand slot. Berserker's Barrage, though strong, may be difficult to justify creating if you already have a strong sword or axe for that element. If you do choose to build one, note that the strong 40% ATK UpATK is boosted

On the next turn, it'll have 3 turns remaining. and 5% DMG Cap UpCan deal big bonus DMG when DMG dealt in one turn reaches a certain amount

When choosing a mainhand other than Berserker's Barrage, consider the strength of its charge attack as your main priority. Give special precedence to those weapons that provide partywide multiattack buffs, such as True Infernal Flamescythe, Hermanubis, 4★ Certificus, etc. These will help you attack more times, thus gaining more charge bar, thus charge attacking more, thus attacking more times in a virtuous cycle.
