I run into a balance problem.
But the question itself can be relatively easy?
If a weapon charges over multiple turns.
How much would the weight be of said weapon?
Previously I tried dividing the weight by the amount of turns needed to charge.
Thus weapons of equal value, gain increased linear damage by increased linear amount of charging turns.
This proves to be slightly off balanced.
Also, the weakness of these weapons are:
-Enemies can go out or range or vision.
-The weapon gets destroyed before fully charged.
Somehow, I should give weapons with a longer charging time. A little bit more power than first calculated. But how much?
Well, maybe.
It really depends on the exact game design of everything else, and how likely it is that something negative will happen while the weapon is charging. Estimate what that is, and then increase the damage by roughly that...
Once I can estimate what to estimate.
I could calculate it ;)
I presume that it has to be linear to the increasing of the negative effects.
So 20% might actually be a nice start to test.
