Current Future said:There's a fusion mod on Havarl, which only becomes available after restarting the Vault, that decreases you're power cooldown by 50%, but if you get a kill your powers instantly cooldown. I'm on my 1st playthrough, on Insanity (of course) running as a Sentinel with Overload on my left-hand, charge in the center and flamethrower on my right hand.
To quote Dr. Oppenheimer: "Now, I am become death."
That mod is great. I used it exclusively once I had it. Played as a soldier the whole way, the biggest issue was ammo problems until I could really do damage with both a sniper and AR.
BTW, first-run insanity is the only way to play this game. Super fun, just enough challenge.
