[@Kafka Komedy] By mold* I meant as in actually mold the crystal in your body. Like the nails on your extremities that look like continuations of the skin. That kind of molding to actually make it a part of your body. 

Also since you said that the power and effects of the Lapis cannot be controlled when mined, meaning that you get what you get, can the power of lightning change between 2 different lightning Lapis? Lapi's A lightning is more powerful than Lapi's B one. Does the stamina used to activate them differ? If you master/manipulate Lapi B, does it limit the power of your lightning, making it weaker compared to Lapi A?

On another note, when using Lapis with passive abilities, does it slowly drain stamina from you little by little? Can some be activated/deactivated at will? Does the activation also cost stamina? Can you master/manipulate passive Lapis? Do you need to hold them in hand to actually gain from their buffs or just hold it in person, like in a satchel that you carry? Similar wise about other Lapis, like the lightning bolt one, do you need to hold it in your hand or having it in your pocket will suffice for casting it? If you master a lightning Lapi, is it easier to master another one of the same element or is it the same as mastering a fire one difficulty wise? Since manipulate costs extra stamina, if you have mastered Lapi A and Lapi B, both lightning, recreating Lapi's B effect by manipulating Lapi A costs more stamina than just straight-out recreating Lapi B I assume, just to clarify.

**Do you gain any additional buff to your spell if you use a Lapi crystal although you have already mastered it?**
