Hi, I am level 3142, and I am going to be the first to get a grade 100 gem.
How did I get specs obscenely high? Well, thanks to this dude over here...
One important thing to note is how to create dual gems. Adding two grade one's them spamming U is losing about 33% special power.
Optimal creation is a G1 of both, combine, make a G2 of each, add one pure to each dual, combine the G3s, duplicate, and repeat with pure G4s, duplicate the 6, etc.
here is the difference at g34: Regular creation: http://prntscr.com/3dgs2c
Special Mix: http://prntscr.com/3dgs6k
Note that the hit count is the same, and the cost to duplicate is the same. This is a difference of 32.9%, and this difference keeps rising at higher levels. It's only a 16% difference at grade 6. It takes a decent amount of time, but it is worth it at ultimate grades (45+).
I now have huge specs. It takes me about 20-30 seconds real life time to get +1 grade. So a minute before +2(needed if want extra specs). I estimate my specs to be about 80% higher than normal, at least blood is.
PS- Level 46 amps got the spec treatment too, they are wicked.
