Upgrade path for Poison Penance Brand of Dissipation Pathfinder

Hello all, I am running a PB Pathfinder.

Here is my current PoB: https://pobb.in/4dteOJPvnSCQ

And here is Rue's, which I'm sort of following (just recently transition to Mageblood so things are a bit of a mess): https://pobb.in/jn8CZc3UhiVN

Now I just bought my Mageblood, and started repurposing my tree for it (hence the abyssal jewel with CB immunity in the topleft cluster socket), yet I'm starting to have doubts about the efficiency of my undertaking.

I ran a Valdo's map that gives another mageblood, so my budget is around ~200 divines, and I'm not sure that investing into this build further will significantly increase my power level. Obvious things I've reviewed:

• Adding Progenesis (buying one for 120+ or however much they're going for right now is mentally killing me and I'm considering actually running some uber Mavens instead, although I'm not sure how well I'll do since I'm shit at mechanics).

• 21 Penance Brand (again, I'm going to level some and corrupt them myslf because the market price is insane).

• My Charms are shit, and I've been very lazy about upgrading them. I can't really afford the ones in Rue's POB but I guess 15% magic flask effect would have to be sufficient.

• Weapon: I already have a 7% corrupted Dawnbreaker and I have unequipped it since I'm running ToH because I don't have Progenesis yet. Some people on poe.ninja are running Saffel's which looks cool but leaves me unable to reach ~95%+ phys as X, probably.

• Finish crafting the wand (force +1 Phys via Harvest aug, probably on a Heathen base instead of Profane because the Int req is really annoying to manage).

• Cluster Jewels -- There are multiple setups, some use Septic spells medium jewels and use a real ring instead of the Herald of Agony one, Rue runs the absolutely insane 12 small passives phys% which cost a fortune and I worry about the liquidity of in case I actually decide to sell my items.

• I'm 99% sure that if I switch to Enlighten 4 I can fit in Malevolence into my reservations, which would be really cool for damage, but I haven't fully mathed out the reservation yet so that's a work in progress.

At the end of the day, what I want from my character is to do all content. Mapping, Uberbossing etc, Sim30 etc. And while mapping is fun with the explosions (I'm pretty sure that asenath's explosions will not clear so I'm going to have to use a 15% charm/TwwT, but that remains to be seen), the single target is just OK (obviously, by improving my wand, getting a 21 gem and Malevolence I'll probably get at least ~50% more DPS, but how likely am I to DOT-cap Ubers?)

In general, I would just like to spark some discussion on the endgame potential of the build and just probably look for some inspiration in regards to what to prioritize and how to make the most out of my available resources.
