u forgot to mention that u can get 100% skill up if u fuse a max level deamon of the same type to another. ex. fusing a lvl 30 ww to a level 30 (or whatever level) ww will add the skill level by 1.

im not sure but bulk fusing deamons is not that bad, u only should avoid bulk fusing mags. but im lazy haha. so i bulk fuse 1* mags and deamons
