PoE Ice Trap, Cold, Duration builds

POB: The video is a T16 Dunes just alch n go. I couldn't decide on whether to start with shockwave totems or the hydrosphere Occultist so I decided to make a bad build that combines them both. Surprisingly, it has gotten me to endgame pretty smoothly and can take down pinnacle bosses. Uploading a video because a few people requested one. Edit: Note on a cool interaction, on-kill effects work with hydrosphere even though it's a totem build (bug?). At the cost of +1 totems from ancestral bond you can make it into a explosion build.
