Storm totem seems to currently have an issue with target recognition.
-Summon Storm Totem
-Totem Kills monsters
—On death effect spawning more monsters after the totem was placed
—Dragging enemies closer to the totem
—Enemies spawning in after the totem was placed
-Totem fails to recognize the enemies until being re-summoned
This generally isn’t too much of an issue, however the buff totems get from storm crows depends on the totem staying active, having to re-summon the totem to get it to hit the monsters really ruins the damage potential this build could have. The other note here is that this can also happen in boss fights with phase transitions.
Here’s a clip I made. You can see the totem losing recognition around the 14 second mark.
