Adaptive Strike (divine, polymorph, transmutation) The naunet chooses adamantine, cold iron, or silver; its melee Strikes count as that type for 1 minute or until it uses Adaptive Strike again.

Change Shape (concentration, divine, polymorph, transmutation) The naunet can take the appearance of any Small, Medium, or Large animal, beast, or humanoid. This doesn’t change its Speed or its attack and damage bonuses with its Strikes but might change the damage type its Strikes deal.

Confounding Slam (divine, emotion, enchantment, mental) A creature hit by the naunet’s tentacle Strike is stupefied 2 for 1d4 rounds (DC 24 Will negates). If the creature was already stupefied in this way, the duration extends by 1 round instead. A chaotic creature is only stupefied 1 instead.
