If you enjoy customizing your virtual home, it's better to get started early. Here’s everything you need to know about crafting and using Mortar in Blue Protocol Star Resonance.
How to get Mortar in Blue Protocol Star Resonance?

At the moment, there are two ways to get Mortar in Blue Protocol Star Resonance. The first one is to craft the item yourself, and for that, you’ll need to unlock the Alchemy and Gemology Life Skills.
Here’s everything you need to craft Mortat:
- Raw Ore of Limestone x1
- Fine Sand x2
- Boiled Water x1
Acquiring these materials is fairly easy. By collecting various Ores, you'll accumulate Limpid Azure Water, which you can refine into Boiled Water at the Alchemy Research. The same goes for Fine Sand, which is also a byproduct of your mining activities.
Lastly, the Raw Ore of Limestone is available through mining Limestone or purchasing the material directly from the Gemology exchange. Once you have all of them, you can craft Mortar by spending some focus.

The other way to get Mortar is by making a direct purchase. If you have enough Luno, visit the Alchemy Exchange, available right beside crafting, and buy the item directly for 1,542 Luno each. This method isn’t optimal if you're running low on currency.
