A previous post outlined various conditions regarding intel available surrounding Naakuals.
It seemed that information regarding the overall colonization was connected to the Naakual's fatigue, rate of Reive appearance, mob repops, and HELM opportunity abundance.
It stands to reason that weapons have nothing to do with the 0 damage.
More likely is that Colonization % is the means whereby Naakuals are made damageable, and presumably, ultimately defeatable.
This fits with SE's overall theme with this expansion. The efforts of one, a few, and an entire linkshell do little to tame Ulbuka. It requires the efforts of the entire server.
