In case anyone likes trying to use uniques (aberrant call) and skills / interactions (putrid wraith idols) no one else is using.
I find this build relaxing and satisfying to play, even though I haven’t tested it too much, and don’t think it will be powerful for end game. Here’s how it might look:
Basically, you just spam wandering spirits for poison, ward and mana, while casting stationary putrid wraiths ahead of you. With your high cast speeds, you get 13 wraiths out really fast, and they output high poison + a bit of bleed DPS over long distances. So it is very forgiving if you want to play safe, or speed run, or if you are spending very little time on crafting or gear like me.
Your dead wraiths will summon zombies for more poison and ward, all your mana spending creates ward, and your transplant will give you more mana and mobility if needed.
I like the idea of AOE using lots of poison darts flying everywhere from 13 wraiths and a few wandering spirits, but AOE is the main weakness of the build.
Bossing is quite satisfying, with dread shade buffed wraiths doing great single target damage.
Best of all, the poison darts are very pleasing on the eye, especially as most other builds are painful with screen clutter. Realistically, it is mostly a potential build if warlock offers the right synergies later on.
