(All fully ascended and maxed out)
I have no 5*'s yet, but have 3 x TC20 up and running (30 pulls, no 5*'s but plenty of 4*'s)
I have 14 hidden blades and 3 rings.
I have multiple Gormeks, Keliles, Scarlets and a Colen (none ascended to their final stage)
Should I save all the hidden blades for future 5*'s? or should I use hidden blades to ascend one of my other 4* fire heros for backup/red stacking (considering I have so many)? if so, which one?
