Solo
This Hammer and Anvil Build is optimized for Serena in The First Descendant. With the latest balance update for this weapon the shotgun is actually amazing.
Core Slot 5: Pick whatever enemy type you fight the most.
Serena must use 4x Ascending Armory external component set. Otherwise you will run out of ammo quickly. Info here: https://alcasthq.com/tfd-serena-build-guide/#best-components-for-serena
