profane bloom ignite occultist , how bad / good is this idea?

hello exiles, so was "inspired" by all the new elementalist ignite builds , especial the ones using obliteration wands to ignite with the chaos explosion. So my take on these "autobombers" is this one

Setup

1. occultist for profane bloom 25% as chaos explosion
2. [[zerphi`s heart]] to enable to ignite (and shock / chill) with these explosions
3. stack ignite chance to 100% (e.g. doryani`s invitattion belt, flask) and fan the flames for prolif
4. use [[blackflame]] ring to enable us to scale these ignites with chaos stats (and get more synergy with occultist)
5. use [[the grey spire]] to scale explosions and ignite dmg at the same time (+ better defence)
6. use [[death`s oath]] to kill and trigger explosions while walking and scaling death aura the same way we scale our ignite , win win
7. use blasphemy with despair to improve dmg and enable chaos explosions in the first place
8. use supreme ostentation to disable attribute requirements (and negating the downside of the amulet and the steep str requirement from death`s oath)

running around at lvl86 as "glasscanon" but early redmaps are doable , using 4L vaal blight to help with bosses but i am rly squishy so i guess you could call it "proof of concept" so far.

So what do you think? is this just elementalist with extra steps? Can you help me make this into a "real" build? Any ideas on how to go from here? Here are some thought i am currently mulling about

• how important is death aura? maybe i dont need it / can replace it with something else
• maybe i could get more Synergie with the other ailments, with flask + tree i am at 45% chance to shock / chil which is nice and could be improved on or abandoned
• having 80/80/80/79 is nice and all but phys dmg exists and i am sitting at 2k life atm
• could go for spritual aid for even more "global damage" (or use it to replace grey spire and make room for something else)
• blight does have a little bit synergy with soal eater (cast speed = faster stacks) but maybe there is a better way or something else with more synergy
• i dont think CI would be viable and we would "throw away" on benefit / reason for occultist in the first place
• what about hexblast, i dont have any experience with it but it sounds like it could have some synergy worth exploring

thank you for reading and your time , looking forward to your input and ideas.
