Mentee coints

hello!
i have a question about using mentee coints.
i wonder, if can i use both types of atribute stones (+60 and +150) on weapons/armors?
lets say i have weapon with 200 atri and i want to do it 300. can i use +60, or sohuld i buy +150?
can i use +150 atri stone on armor (i know max is 120), or sohuld i buy 2x 60 and put it to the same armor pice?

or its possible to use that items only one time, and the rest should be done in normal way (using crystals?)?
i say there is atribute change crystal... does it works on armors, or just on weapon?
i think thats all for now

 

after 150+ on weapon or 60+ on armor you have to use crystals not stones as i know.

 

u cannot use the stones 60 or 150 as crystals so no you cant go over 150 in weapons and 60 in armor...
