(reupload) Sorry for the obnoxious shaper filter lol.
Here's a map showcase of the Herald of Thunder Elementalist Autobomber I'm currently running in 3.19: Lake of Kalandra league mainly for altar farming.
Level: 95
~7m Sirus DPS
This is a moderate budget version of the Herald of Thunder Autobomber build that utilizes the Annihilating Light staff along with the Lone Messenger cluster notable to do big damage. The playstyle is quite fast and relaxing for mapping since most of the time you'd only be running around using Phase run to clear the packs and occasionally use Storm brand/Flame dash to apply the initial shock for the map boss/beginning of the map. You can look at the PoB for the other setup that I have in the video.
BEWARE: its far from being the tankiest build out there and its possible to die from one shots especially for dangerous mods or if you are running Wrath of the Cosmos.
Current cost: ~25 Divines
