Calcharo Build

Lupa's Signature weapon is an increase in damage for Calcharo, albeit a very small one. As it buffs Resonance Liberation DMG, it's able to buff Calcharo's Death Messengers which concentrate the majority of his damage, however it will not buff more than 2 Death Messengers due to the short nature of its buff (Calcharo cannot extend this effect without reducing the number of Death Messengers he can perform per rotation). As a result, the increase this weapon provides for him definitely exists, it's simply very small.

Top Broadblade option only in competition with some 4★ weapons with multiple copies invested or limited 5★ weapons. Offers high base ATK, ATK%, a good amount of Energy Regen to save at least 1 sub-stat on gear to be reallocated to better uses and a stackable Resonance Liberation ATK DMG% bonus that ramps up as you use Resonance Skills.

A very competitive option to his best in slot if you didn't pull it on the standard banner. The high base ATK, as well as the 24% crit rate and 12% DMG bonus substats are very nice, especially if you need your weapon to even out your crit ratios, in which builds it might outdo Lustrous Razor; and while barely used on Calcharo at all, the Resonance Skill DMG boost is always a small damage increase.

Jiyan's signature weapon that's not only fantastic for him but also usable on all damage-focused Broadblade users. Offers a huge main stat of CRIT DMG% granting excellent scaling, 12% permanent generic DMG% and up to 48% increased Heavy ATK DMG% after using 1/2 skills and or a Resonance Liberation.

Strongest 4★ Broadsword option, granting main stat CRIT RATE for excellent scaling and an incredibly easy to access bonus ability which grants a stacking ATK% buff that only requires you to use Basic or Heavy attacks during your rotation.
