1. you can open your crystal bag by clicking on it and you have 5 spaces to place/ remove crystals.Crystals will improve the crystal bag holder's resistance to whatever type crystal you put in there, your resistance will depend on the size of the crystal you place in there.
2.Charms can be placed in the slots by dragging and dropping into the appropriate charm slot. There are no skills to do this. it can be done right away.The majority of us who have played DD will realise that the slots are now crossed permanently and dont open after using certain skill levels like in DD.which is the same mistake I made until I thought hod on this is the second act and I am still not able to charm anything.. oops.. <img src="/ubbthreads/images/graemlins/up.gif" alt="" />
