According the Guild Wiki they are supposed to be extra vulnerable to SS, but they seem to take 0 damage. Insidious Parasite works just fine though on them possibly because its vampiric and doesn't count as normal damage?
They don't use any enchantments, it seems. There are instances, however, when a couple of hits now and then cause SS damage to be normal but then they do something and its back to 0.
Sorry if posting in an incorrect forum.
