Rescue Biorr of the Twin Fangs

If you help Biorr of the Twin Fangs, he will join you with your fight against the Penetrator. With Biorr's help, the fight should be extremely easy.

How to Rescue Biorr

Where to Find Biorr

Wait for an Attack and then Strike

Penetrator - Dodge Attacks
The Penetrator's attacks are large, and dodging them will be easy once you get used to the timing. Dodge its attacks and then attack to defeat it.

Watch Out for a Thrust Attack when the Sword Glows

Penetrator - Sword Glow
Watch out for a piercing attack when the Penetrator's sword begins to strongly glow. It is a very powerful attack that can one-shot you. Be sure to dodge this attack.

Be Sure to Maintain your Stamina for Dodging

Be aware of your stamina throughout the fight. The Penetrator has an aggressive move set which makes it easy to burn through stamina by constantly dodging.

Do Not Hide On the Pillars

The pillars offers little to no protection against the fight with the Penetrator. His attacks will easily break the pillars so if you wish to heal yourself, aim to use an item after he attacks.

Penetrator Cheese Strategies

Firestorm Strategy

Whiel not exactly a cheese strategy, it can still be called an auto-win button.

Recommended Gear
Clever Rat's Ring
Firestorm (clear 2-3)
Morion Blade(clear 4-3)
Ring of Magical Sharpness
Some Spices

Before entering the fog, bring yourself to critical health (can easily be done by letting enemies hit you or using a self damaging weapon like the Makoto). After entering the fog, bait one of his attacks then immediately use Firestorm. Due to the Penetrator's small stature (compared to other bosses), the Firestorm may not immediately kill him so stay away and replenish your MP with some spices then repeat.
