OK light objects cause 2 clicks of damage and heavy cause 3 clicks right. But is this in addition to the normal damage a fig inflicts according to his dial. I.E. if I'm using (V) Hulk whose doing 4 clicks of damage then he uses a heavy object in close combat to smash someone, does him hitting them with a heavy object do 8 clicks of damage? And how about attacking with objects using TK, same question.

Ok throwing light objects cause 2 klixs of damage. Throwing heavy objects cause 3 kilxs of damage. Now using them in combat. LIght objects add +1 damage and Heavy objects add +2 damage. To your attacks.

Close Combat: A character carrying an object who is given a close combat action must use the object in their attack. On a successful attack, a light object inflicts 1 click of damage in addition to the damage inflicted by the character; a heavy object inflicts 2 additional clicks of damage.
Ranged Combat: A character with Super Strength can also throw an object at an opposing figure. To throw an object, give the character a ranged combat action, even if his range value is 0. A light object has a range of 6 squares and will inflict 2 clicks of damage on a successful attack. A heavy object has a range of 4 and will inflict 3 clicks of damage.
