Guide

How to play this build

Forbidden Sanctuary monsters are level 400, this is a tough dungeon and if you don't have an optimized build it will take a while to clear. 

All monsters are legion of breach, except the endboss is legion of truth. They are all weak against electric. 

For mobbing, we just use a Restored Relic multi-hit fire-optimized weapon. Last boss we use Excava, which deals insane dmg vs the boss because he is weak to electric.

I usually range between 4:45-5min runs with this Serena Build for The First Descendant.

You must apply Defense Neutralization mutant cell on bosses to get a huge damage boost vs bosses for a bit. The debuff only works when the boss has full HP.
