the overcharge skill works like this:
- its a supportive skill, u need to activate it. clicking the skill-icon will "highlight it = green" to make it automatic, otherwise u need to click the key that is was assigned (check key-settings)
- when the skill is activated, it will countdown from 5>0, when 0 its ready.
- u need to use knights blast (for now, as theres only 1 cannon active-skill at the moment)
- when u attack a monster with knights blast "and" the overcharge is at "0" it will use the overcharge bonus damage
- after that the overcharge need 5 seconds to reload, so 5>0, when 0 it will be used again.
that means, when u attack monsters using knights blast it will only use that attack while the countdown is >0
when 0, it will use "both" knights blast+overcharge for increase damage and repeat.
I say 5 seconds, but thats when its fully upgraded. u start with 20 cooldown.
