PoE builds similar to Path of Exile: Detonate Dead / Volatile Dead Spellslinger Necromancer

I've spent 45-50ex so far. With \~30ex budget i had roughly half the damage but same defences.

gems awakened cascade 20c awakened unbound 15c divergent inspiration 4.5ex x2 (dont really need divergent inspiration on desecrate) detonate dead 10c withering step 20c enhance 4ex x2 (save 4 ex if you use level 3 enhance on withering step but you lose 1 stack of wither) desecrate 1 ex herald of agony 15c 18ex 80c gear (including essences + eldritch currency to roll prefixes/implicits) 2x 6 link 5ex bow 5ex (crit essences until attack speed, wipe prefix, cannot roll attacks, beastslam/annul prefix) asenath with enchant 2ex body 3ex gloves 2 ex ashes with good rolls 1ex, 60c an

The idea is to play it similar to the Diablo 2 Necromancer, just let the bodies hit the floor, I mean explode. I think it will have a good clearspeed, but will have problems to kill bosses, something I would be fine with. It would look along the lines of following PoB: Create the first corpses with desecrate totem (to also use the Maurauder Ascendency), the scorch them with scroching ray while let them explode even more with infernal cry.

POB: These flasks is for mapping and for single target none of these really do much since I am indeed aliment capping on end game bosses like shaper and not aiming for ubers.

Since I am crit capping and have quick a lot of increase damage taken so even bottled faith is not that great either.

I got lucky and get 2 doctors from ritual and managed to upgrade my Bow and get corpse pact jewels and now I am free from skitterbot reservation. However I am not sure what I should be using now that I am here. I should be able to afford an reservation enchant but I do not really have sockets to spare anymore (or is the combustion setup even worth it?). Is Petrified Blood worth using in my case?

So here\s my Coc DD necromancer I\ve been building around for the last couple days. Since the new amulets are chase items I wanted to try something that was cheap and I knew it was still good So I tried the Leadership's Price. This item combine with Melding and Aegis is a very good combo IMO. Just in case someone got interested in playing this build and have some ideas on how to improve the single target dps I would appreciated that. I\m using reckoning to spwan desecrate but against single targets it is not that effective. I already tried that Arcanist brand and for me was way too clun
