Hey guys, so this is my first league I started about a month ago almost. I ended up with going seismic on my second character and currently I feel pretty solid, but I feel like I am missing some major dps somewhere and I just cant seem to see where. Besides going to the unusual gems and getting level 100 ,what else could I do to take my build up another level? https://pastebin.com/Wu7UWq7S

Any help is greatly appreciated, as I mainly wanna use this league to learn as much as I can before the next one starts.
