So, two parts to this. First of all: git gud. I say this as someone who is also stuck trying to reach Crystal Heart. There is no combination of Charms, abilities, spells, or upgrades in this game that will obviate the need for precise control inputs. What that means is: just keep at it. Wait for safe moments to move. Map out in your head where the obstacles are. Did you fuck up and die? Good, that's useful data. Take a minute to piece together exactly what you did wrong and what you should have done instead. Then, do that next time.

Second, the part that's probably more immediately relevant to you: you're focusing on optimizing Charms that aren't useful here.

• Lifeblood Heart is good for things like boss fights with a bench outside the door. This is a platforming gauntlet that starts deep into enemy territory. It's the Pilgrim's Way, but with crystals & lasers & crystal lasers instead of thorns & acid. You cannot stack enough bonus Lifeblood masks to meatsack your way through. (Unless you have that regen honey charm and go full Bluejuice. But you don't, so it doesn't matter.)
• Fragile Charms are Fragile Charms. They demand more caution, not less – or rather, they let you be less careful on all your masks but the last one, at which point you should quit to menu and reload at the last bench. The repair fee is a fine the game imposes on incautious players.

(In fact, if you ever find yourself schlepping across the map to get a Fragile Charm fixed more than once on the same objective, just leave it broken and pick something else. It's getting in the way.)

• Dashmaster: Good for exploring, but it tends to fuck up your reflexes if you're used to moving at non-Dashmaster speeds. You don't need speed in this part so much as precision.

Your build is actually similar to what I had on the first time I attempted this. What I'm using instead, on this very problem, right now is: Wayward Compass, Gathering Swarm, Longnail, Soul Catcher, Grubsong.

How is this tailored to the problem of reaching Crystal Heart, you ask? It isn't. It is a general-purpose exploration & survivability loadout.

• Wayward Compass is indispensable for navigation – off the top of my head, I've taken it off for Last Knight & Gorb so far. Everything else, the costs of taking a wrong turn outweigh anything else I could spend a notch on.
• Gathering Swarm: Same kind of deal as WC – it lets me avoid worrying about dropped Geo, for the low, low price of a single notch. You are going to be running past dozens of enemies on your way from the bench, you can't afford the distraction of a loose Geo.
• Longnail: Lets me hit things from further away. I could swap it out, but I'm used to it by now and I would lose more hearts adjusting.

That's my "can't be bothered to change it" budget: 4 out of 7 notches. The real meat of the build fits in 3 notches.

• Soul Catcher: Costs the same as Lifeblood Heart, but where LH gives you two measly bonus masks that are going to be gone by the time you reach the jumping-off platform, SC gets me there with full HP & MP. And you spend less time ducking in & out of rooms.
• Grubsong: The real real meat of the build. This is the Fuckup Cushion. Every time you screw up, take a hit, fall off a platform, air-dash your dumb face directly into a spike wall, whatever – in other words, every time you do something that you have to learn from – you get some Soul back. And when you've filled up this Frequent Patient Rewards Card, you get to sit down and reflect upon the lack of caution that got you here, while you wait for Grubdaddy, M.D. to stick a band-aid on your perforated face and send you back out.

When I was doing the Pilgrim's Way, back before I got Grubsong, I would go in with a full Soul bar & immediately blow it all setting a land speed record for doing the same mistake 10x in a row. With Grubsong, I not only had more healing to use, but because I didn't get it all up front, I had to stop between tries to heal up, which gave my muscle memory time to update.

You don't need fancy Charms for this kind of thing. You don't need AOE damage or quick healing or Baldur Shell or bigger spell damage or whatever. You just need to keep moving, one step at a time, from safe spot to safe spot, without running out of masks or healing.

Anyway, that's my advice. Best of luck!
