Let me explain in detail that this kind of stone can generally be called "the only equipment".
Are all cut from the longan nucleus. Your own equipment can only have three stones cut from longan at most.
What's in your bag is optional. You can put all the equipment in your bag on the stone cut from longan stone, but it is impossible to change it when changing equipment.
Give another example:
You can plug three 34-strength devices into your equipment, no problem.
Three 34 agile, no problem; 1 34 strength, 1 34 agility, 1 68 storm, no problem; If you want to add a tolerance of 5 1, it won't work;
All the equipment in the bag can be changed to 34 strength, but it can't be changed if it violates the above rules.
