Reactor made the difference in my defiler time with Ines

So I went from a reactor with crit dam\cooldown to Colossus dam\tech dam and cut my time in half so far on the first try. And my Colossus reactor is one level lower upgrade than my other too. I didn't think it would make that much difference but glad I farmed it. So if anyone else is wondering, a reactor can make all the difference in damage depending on what you are doing (yes I consider myself casual so forgive my ignorance haha)
