Talisman Weapon Causes Black Screen Death in Bodach Ritual Boss Fight

Hi, I would like to report a bug related to the new Ritual boss Bahlak.

When using a Talisman weapon, the character model appears to become abnormal/glitched during the encounter. After reaching the second-phase platform, the screen turns black and the character is killed.

This makes the boss fight impossible to complete while equipping this weapon type.

Oil Barrage is my main damage skill, so I cannot temporarily unequip the Talisman weapon to progress through the fight. This leaves me completely stuck with no viable workaround.
