you do not get extra elements from SOX
I have had from Breaking stuff (best chance with 3+ blue, ideally lucky as 1 of them):
4 Lucky
2 fogs 35% and 5%
2 Penetration 35% and a 5%
1 Warriors 5%
this is from breaking about 40 - 50 Items with 3+ blues...
Interestingly the Stone of Warriors came from a 64 Blade with no blues at all!
at the time I was breaking the Blade, I went to break a 64 Glaive with blue BR 5%
had 4 free slots, clicked the Fuse button - it canceled the destruction and said I needed 7 free slots!!!
I excitedly cleared the space, clicked the Fuse button again, the Glaive flashed and disapeared...
and I got...
a bunch of elements, no stones at all
I have read this from before too, it is always random what you get...
But only 8th Deg seem to give stones from items with no blues...
