A second attack allows for mitigation of the miss chance in effect instead of an all or nothing you have the chance to miss and still do damage.
Good point, but i think that it would be easier to implement if high level monsters get the backswing ability.
Increasing the number of attacks across the board for a champion will make them more of a threat across the board, but I think it would be more balanced. A general point of order here also if this were to be implemented (double attacks from a normal attack), this could replace give me initiative traits if they didn't want to give it to every hero. The double strike is a particular useful trait with tarth... especially if you go assassin and choose precision a couple of times. You are then accomplishing the same thing I suggest.
I would like to see it done through a different stat as opposed to a spell and automatically compute the damage as two strikes on the same unit. Decimate is a powerful ability, but I think is the wrong approach to a balanced system of having groups of 7 as 1 unit so the damage is normal * 7 vs. a champion which is normal * 1 + BUNCH OF BONUS. I would like to see it more like normal * 3 + some bonus. Making it so you don't have to min\max your champion to be effective throughout. I think there is more possibility, if they could add this into the core game.
Hmmm, if units would have a base initiative of 100 and if heroes would have a base initiative of 125 the heroes would get always extra attacks, too, and it would work for physical attacks and for attacks with spells.
Assassins, defenders, warriors and high level monsters would get the second chance ability, that works like backswing, to allow a mitigation of the miss chance.
If medium sized heroes and monsters would get the evasion ability, that increases the initiative by 25 (100 > 125) and reduces the number of lost hit points (not the damage) of an attack by an enemy group by 50 % it would make them stronger against groups. If you combine the evasion ability with the decimate and second chance abilities you would get this:
Hero attacks a group of 4 units:
The attack misses and second chance gives the hero another attack that hits and inflicts 10 points of damage
The decimate ability increases the damage by 100 %, because the group has 4 units, to 20 points of damage
A group of 4 units attacks the hero:
The 1st attack hits the hero for 10 points of damage and the defense reduces the damage to 4 points
The 2nd attack misses the hero
The 3rd attack hits the hero for 12 points of damage and the defense reduces the damage to 5 points
The 4th attack hits the hero for 10 points of damage and the defense reduces the damage to 5 points
The evasion ability of the hero reduces the lost hit points from 14 to 7
