For building an Operator as a tech-specialist? Well, demolitions specialist more like, but explosives fall under Tech-Use, soo...
Our entire squad are Guardsmen, no Specialists, so I decided to make an Operator who specializes in demolitions and minor repairs.
Seeing as my chance, on an unmodified test, to set up any explosives (Int 32, Tech-Use is Trained) without incident is 42%, and the chance of it going off in my hands is something like 28% (unless I'm flubbing the math?), I was looking to improve that. I feel it's slightly... ah, risky.
Are there any things that are good for that, besides just buying some Int increases and higher levels of Tech-Use?
