EXCAVA, while not as powerful as some of its competition due to its lackluster base stats, proves to be a solid option to use after obtaining it from the Battle Pass. The modules included attempts to patch its weaknesses by improving on Firearm ATK, Fire Rate, and its Critical Values.

The Special Mods you will utilize for EXCAVA varies. If you plan on doing Void Interceptions, bring Mental Focus; otherwise bring Sweeping Squad. Furthermore, it is recommended to add more Rounds per Magazine to reliably stack up its Unique Ability and build up more critical hit rate.

The optimal way to use Excava is to not expend the stacks you have built by only firing from the hip to avoid using your grenades. Doing so preserves the additional base +21% Critical Hit Rate you get from the stacks, increasing your overall DPS.
