Seems Seregios is not the only monster with interesting weapon 's mechanic, the Chaos Gore Magala 's weapon also have its own feature.

See that dual Affinity ? That 's right, the Chaos Magala can randomly inflict High damage or low damage , but then you will notice that the black beam will appear frequently , more than the red beam , which is bad.

However, the weapons will shine when you overcome the Frenzy Virus , when that happen , both affinity will combine plus the Frenzy Virus +15 % affinity bonus , so we will have this : 25( minus will become plus ) + 10 + 15 = 50% aff  , but if you fail , no bonus for you. Bad mechanic is bad. I will keep my shagaru magala 's glaive.
