Who knew that wraiths are rigid creatures, being in same class as DM’s, crabs, crystal guardians. As such, they would take extra extra damage from a Duelist’s pickaxe.
On the same time, Mimics are not rigid (they’re demonic). They’re one of the very few demonic creatures that can appear in sewers.
That’s interesting, I always thought they were like octopus, they just squished themselves into shape and changed their color.
