You can take it at any time under normal circumstances. Perception doll (plot), power doll (above the statue in the lobby of Energy Building) and intelligence doll (Boston Library) are the best. Other agile, endurance, luck and charm dolls are in the high-grade area, and it is difficult to get them in the early stage.

In addition, because the upper limit of the attribute is 10, you have to reach 10 to break the upper limit. If you add the attribute to 10 in advance and then take the doll, you can reach 1 1.

Other non-attribute dolls can be taken at will.
