I’ve had a lot of good times with my dark/devices blaster. Not the greatest DPS but still solid. The -tohit from dark really syncs well with devices. The goal here is to hit the range def cap and keeping enemies at bay.
When I solo, I go group to group and set up with a trip mine and hover. I start my chain with torrent (be sure to slot a proc to convert kB to KD, I recommend the overwhelming force set for the KB protection) and afterwards tenebrous/soul tentacles to keep enemies locked down. From their, I normally snipe (instant snipe) any leftovers and siphon life for any health recovery. This mixed with my nuke really just keeps me going from group to group! ❤️
