So, If a person solo's RV nightmare, and BC normal
You get about Total of Gems which Can make At least 2 Shining Gems, so the Third can be bought for Gold.
So in 2 Days you'll probably have 6Shining's +2PC Ready to make Frag arch Shard
54Scratched Gems=6Shining+2PC = Frag arch Shard
People normally, Start dealing with Shining Gems, thinking it would easier, but in S4, Since i don't know the prices of other servers, This is probably the easiest way to think and do so, i don't know if I' m right or wrong but this is how i think.
If there is another way or so to Make a Frag arch Shard quickly or easily , please tell me.
