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.
Psorek- It won't change at all. Even at this low hit, blood+orange outstrips pure blood and pure orange. The blood and dual both have same multiplier. So will they 40-60 levels from now. The difference will only get greater- Use Dual-Black. It's hands down the best.
Let's say, that you want to do orange/black gem of grade 6. You can eg. do g5 O and g5 B and combine them, but there is a better method.
You create g1 black and orange and combine them to g2 orange/black. Then duplicate it and create g2 orange and g2 black. Then combine g2 orange/black with g2/pure orange and g2 orange/black with g2 pure black. Then combine freshly created g3 gems together.
You've got now g4 black/orange, which is slightly more powerful than a classic one. Repeating process incerases the difference further.
I'm still pretty low level, but I got.. inconsistent results trying this. The first round is easy enough, following until I have a rank 4 BO. Then I dupe it, make a rank 4 O and a rank for B, and combine (BO+O) + (BO + B) to get a rank 6 BO?
I did that, then again to 8, then compared against a plain 8, and didn't see the difference except like 0.04 leech. The bloodbound was exactly the same. Am I missing something crucial, or is it just that I have pretty pitiful stats still (skill cap at 8 still, so..)
