Activity in the CoTCC forum is slow so I'm posting this here. I'm a little unclear on how the havero tentacles in the Acropolis of the Thrallkeepers are supposed to perceive their targets. The stats give them blindsense, which reads:
"Using nonvisual senses, such as acute smell or hearing, a creature with blindsense notices things it cannot see. The creature usually does not need to make Perception checks to pinpoint the location of a creature within range of its blindsense ability, provided that it has line of effect to that creature. Any opponent the creature cannot see still has total concealment against the creature with blindsense, and the creature still has the normal miss chance when attacking foes that have concealment. Visibility still affects the movement of a creature with blindsense. A creature with blindsense is still denied its Dexterity bonus to Armor Class against attacks from creatures it cannot see."
So, the havero tentacles don't have to roll to perceive a target, but since they can't see (only the tentacles are in the encounter, not the full creature) the targets get total concealment and the 50% miss chance? Or does the total concealment apply only if the target has invisibility or something similar?
