Devourer Mutant=double ability

[Cynxos]

While playing against destiny, she got a mutant Devourer with paradox.
Now the thing is, the devourer still had its ability, its NATURAL ability active, as in it would take 1 random quantum from me, and turn it into darkness+ the mutant ability, which in this case was paradox.
Now when I think about it, it seems quite bizzare on one hand, and makes sense on the other.

Well, I'm no expert, but devourer's quantum taking ability is passive, where as paradox is active. It's likely mutate only changes/adds active abilities, and leaves the passive.

This is the same as anything mutated into graboid is burrowed, even if they got a different active ability.
Consider this bad or good luck

[Lucifear]

This is not a glitch
Creatures that have certain passive abilities will keep them when they are mutations.
Examples include this, shrieker coming into play burrowed, and more recently, casting reverse time on a mummy from a mutation will give you a pharaoh, but with a random ability!
