How do I get gemstone avalons like Str, Spd, Crit, and Arm. How do I combine properly to get them too?
Completely random. The only things that affect what gemstone you create are the ranks of the gemstones you fused. Fusing an A rank gem gives a higher chance of creating an A rank gem, fusing a D rank gem gives a higher chance of creating a D rank gem, etc.
Ezpz buy premium gemstone (90 rc) or gemstone gemstone (3k carats) and wish u got nub luck. U can also mix them (waste of time usually get **** from mixing).
Let me backtrack, mixing should result in random gems. What I should've said is I wish they could be stacked. So let's say you have 2 B ranks, add them together and you'll get an A rank.
