I have a related question - what skills increase target subsystems? I can't seem to find any documentation on this (shocking, I know ). Thanks!
The skills that boost them are
Starship operations training
This only affects the drain amount and not the percentage chance to disable system.
Alsousing sci team just before using the ability increases the drain due to boosting operations training
by around ~6.
I tend to use beam target shields III in front to knock shields down followed by quantum torp high yield III.
Then i use beam target engines in the back for someone who always seems to try to follow me when i attempt to escape.
