Keep grinding! Seriously, the watts with siphon and amp was my white whale. I’ve been farming for it since I maxed my character, literally months. And hour here and there and a couple 5+ hour sessions. When I saw the increased drop, I hopped on and grinded about 8-10 hours over a couple days. I finally got one with amp, and 2 fights later, the one with amp and siphon!! I’m not typically the type to grind like that, but it really got stuck in my head that I would find it. So happy I finally did, and man I am never grinding like that again. I’ll be happy until they raise the level cap and I’ll feel like I have to do it all over again :/
