I'm not 100% sure but it is my understanding that the difference between final area and the initial is how much it will expand. Basically having a high final area means it would blast out like a cone.
Maximum damage is how many times the damage can be dealt.
ie: Carrion Swarm with maximum damage of 200 and Collision damage of 100.
This means that it will collide TWICE and then it will be maxed out and deal no damage to units.
Thnx alot! But about the max damage, u say how many times it can do dmg, but one of those wave skills (think shockwave) has max dmg of 900, so it deals damage 900 times??
