whts the damage thing which is under attack, which appers on the rite side of the screen when we duble click on any unit????

Thats the amount of damage one troop in a stack makes and the higher numbers below is for the whole stack

The number in parentheses with a plus (+2, etc.) is a modifier. It shows how much attack or defense advantage due to various factors has been added to the first number. It has already been added in, not extra above the first number. Being in a your castle gives you extra defense. Being on blood lessens your attack. Being on rubble lessens your attack and defense. These are some of the possibilities.

but if "damage" is the 1 which determines how much attack we'll be able to do then whts the use of the "attack" thing???

is it tht when our attack increases so does our damage?????

that i think is very right indeed.

The higher your attack rating is, the more damage you do and also if you have a higher level stack you can do more damage as well
