From Dragon Quest Wiki
Chilling Chuckle is a mockery skill that reduces the Tension of its targets and is one of the signature moves of the templar Angelo.
Dragon Quest VIII: Journey of the Cursed King
Angelo learns Chilling Chuckle after allocating 52 skill points into his Charisma skill tree, replacing Sarcastic Snigger. It costs 3 MP to use, and will target a group of enemies.
Dragon Quest Heroes II: Twin Kings and the Prophecy's End
Chilling Chuckle is already known by Angelo when he joins the party. This time around, the name of the skill is quite literal as Angelo is able to freeze a group of enemies solid, costing 4 MP to use. It does not inflict any damage.
