1. Drop Well of Suffering and Well of Darkness.
2. Use staff skills.
3. ????
4. Profit.
You may need to wait until you’ve got enough skill points to get the relevant wells, but I rarely-to-never kite on my necro (level 45) during solo PVE and I’m fine with several mobs, a veteran in the mix, etc. Ranged can still be a pain because they’re difficult to round up tightly but otherwise, it’s pretty smooth sailing. On the rare occasion when you have too many or it’s taking too long, Death Shroud for a bit until your wells are back off cooldown again.
