Individually for units (like invisibility, fire modes, etc).
1) full range (even if target is closer, so shot through) - default damage and reload time;
2) full range (even if target is closer, so shot through) - smaller damage and less reload time;
3) only necessary range (no shot through) - bigger damage and same reload time;
4) only necessary range (no shot through) - default damage and less reload time.
First switcher is for range (full or necessary).
Second slider - to choose between power and frequency. Or a switcher for power, may be between 1, 25, 50, 75, 100 percents, so frequency will be auto-adjusted.
