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.
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.
