Been waiting for this kind of gem for a long time. Currently the only gem with this kind of stats drop from heroic Mechanar (
This is a perfect gem for an affliction warlock. Finally we can activate some more gem bonuses on yellow slots (Girdle of Ruination, Voidheart Robe) and overall just get more +hit if you're in need of it.
Very nice for shadowpriests too, currently only option to yellow sockets was 8int or 4crit/5dmg, crit is rather useless for priest and i take spelldmg over int anyday.
This was introduced in 2.1, however, it is unknown exactly where the design for this gem is found. Perhaps as a reward or drop from some of the new 5 man content?
New rare gems with 2.1:
Great Dawnstone (8 Spell Hit Rating)
Veiled Noble Topaz (4 Spell Hit Rating | 5 Spell Damage)
Wicked Noble Topaz (4 Critical Strike Rating | 8 Attack Power)
Balanced Nightseye (8 Attack Power | 6 Stamina)
Infused Nightseye (8 Attack Power | 2Mp5
Thundering Skyfire Diamond (Melee/Ranged Haste Rating Proc)
Relentless Earthstorm Diamond (+12 Agility | 3% Increased Critical Damage)
All designs for these new gems are random world drops, only the Relentless Earthstorm Diamond is obtained from the Consortium Quartermaster once you reach exalted.
This is quoted from tivelositos from the sticky in the mage forums by Swindy, possibly one of the most helpful people to mage damage calculations in TBC
"So lets convert those formulas to a real world example. Let's take a fire mage with 900 spelldamage, 100 hit rating, and 30% to crit with fire.
+50 spell damage would mean (B+c*(D+n))/(B+c*D) = (902.5+1.035*(900+50)) / (902.5+1.035*900) = 1885.75 / 1834 = 1.0282 which is 2.82% more DPS.
+50 spell crit rating would translate to 2.26244 more crit chance (1.1*(C+n)+1) / (1.1*C+1) = (1.1*(0.3+0.0226244)+1) / (1.1*(0.3)+1) = 1.35488684 / 1.33 = 1.0187 which is 1.87% more DPS.
+50 spell hit rating is 3.96825 more hit chance on top of the 7,93651 hit chance the mage allready has (0.83+H+n)/(0.83+H) = (0,83 + 0,0793651 + 0,0396825)/(0,83+0,0793651) = 0,9490476/0,9093651 = 1,0436 meaning a whoping 4,36% more increase in DPS!"
Best raiding DPS caster gem period as of right now.
Are these in game yet?
what gem do you guys think is best for a 0/21/40 lock? ive been told veiled noble topaz but also be told potent noble topaz ( +5 Spell Damage +4 Spell Crit Rating) i do need more hit but that crit wouldnt be bad since when i crit its just crazy damage (7k in raids)
