Blue crystals blocking your path in Pragmata? We’ll show you where to find the Lim Eraser and how to dissolve filament masses.
Pragmata’s level design encourages you to revisit each sector multiple times after unlocking it. As you explore the early areas—“01 Solar Power Plant” and “02 Mass Production Array”—you’ll notice certain paths blocked by gray rock formations with glowing blue crystal spikes. These “filament masses” block optional routes that often lead to hidden items or handy shortcuts. Here’s when and how you can clear them.
Filament Masses: How to Destroy the Blue Crystals with the Lim Eraser
To destroy filament masses, you’ll need a special gadget—the so-called “Lim Eraser.” You’ll find it in the final third of Sector 2, “Mass Production Array.” In Block 5, the “05 Lim Recycling Facility,” you’ll come across a terminal in a storage area that unlocks a data chip.
During a short cutscene, Diana reads the data and unlocks the Lim Eraser for you. It’s impossible to miss, so all you need is a bit of patience until you reach it.
After that, you can destroy all filament masses and clear previously blocked paths. It’s worth returning to earlier sectors to explore areas you couldn’t access before. To dissolve the rock, simply approach it and hold L1/LB when the prompt appears.
