Extreme damage from Albion on Lance Master?

I had to finish Oreha Prevesa to advance my Lance Master’s progression, and noticed during the Albion fight, that no matter how much I dodged or mitigated every other ability he used, his frontal lightning breath attack in Electric mode would one-shot my character. This is the only character I have ever encountered that with, and I have 3 other characters which have done that quest.

Seems to be a bug in the algorithm of damage assigned from that attack specifically to the Lance Master?
