Tips for Defeating Molten Fortress




Hard Mode Guide

Connect the Rods During Its Immunity Phase

The First Descendant - Connecting the Rods
As you damage Molten Fortress, it will eventually fill up its Frenzy Meter and position itself in the middle of the arena. It will then enter its immune phase and summon six rods surrounding the area. To remove its immunity, you must successfully connect the rods to each other.

To connect the rods, you must shoot the terminals hanging in the middle of each rod until they all have arrows pointing to the right. You can determine if you successfully connected two rods if you see a line of electricity in between them.

Shoot the Fire Balls to Prevent the Rods From Resetting

As you try to shoot the terminals in the right direction, Molten Fortress will throw fireballs heading toward the rods. These fireballs can overcharge the rods, which is indicated by the set of bars underneath the terminals.

If these rods become overcharged, their terminals will reset, and the arrow will point in its default direction.

Avoid the Rising Flame Pillars

The First Descendant - Avoiding Fire Pillars
During its immune phase, Molten Fortress will summon multiple flame pillars rising from the ground. These pillars can do significant damage to you but are relatively easy to deal with, as you just need to constantly move to avoid them.

Aim for the Core and Head

The First Descendant - Aiming for the Core and Head
The easiest weak spots to target while fighting Molten Fortress are its core and head. Aim your shots in these areas as much as possible to try and bring down the colossus.

Deal with the Roly-Poly Summons

The First Descendant - Killing Roly-Polys
While fighting Molten Fortress, it will summon numerous Roly-Polys, especially during its immune phase. Deal with these enemies first to prevent them from obstructing you from the mechanic and to gain recovery items and bullets as well.
