Now you can actually make the AH split the results easier, by color, then add the surname of what it is supposed to add to as stated in the post above.

Someone help me with this question. This gem is clearly red socket according to the data. But I see it appearing in all the sockets. Prime example is Aspe from D&T;: http://armory.worldofwarcraft.com/#character-sheet.xml?r=Korgath&n;=Aspe

He puts them in all the sockets of his spellstrike and frozen shadoweave set. And these are mostly blue and yellow sockets. How? I would love to upgrade all my sockets I have to get that +18 or +27 on each piece of gear I have with 2 and 3 sockets.

+9 spell dmg = 9 spell dmg

Stacking +damage gems for raids is a bad idea. While +damage gems give a visible and obvious increase in DPS, +spell hit rating will increase your DPS much more than +damage against raid bosses.

As a Mage you will have a 17% chance to miss. You can migitate 16% of that by stacking +spell hit rating gems. The two blue gems give +8 spell hit rating and +9 damage, and is compared in the conclusion (scroll down to the bottom).

Spell Hit Percentages
+12.62 spell hit rating is required to gain 1% hit. Therefore, +8 spell hit rating will give 0.634% hit. +4 spell hit rating will give 0.317%. +1 spell hit will give 0.08%.

1% Spell Hit = 1% increase in damage
No matter what amount of +damage or +crit you have, 1% Spell Hit will always equal 1% increase in damage.
The roll for Spell Hit takes place before the roll for resist and crit.

Imagine you could cast 100 Fireballs, each hitting for 1,000 damage. You would do a total of 100,000 damage, assuming you could somehow obtain 100% Hit Chance, no crit and no resists of any kind. This is -0% damage.

Now bring that back down to earth. You have a 17% chance to miss against bosses. We will ignore resists for these calculations. 17% miss would bring your total damage down to 83,000. That is exactly -17% damage.

You decide to get 12.62 spell hit rating, equaling to 1% Spell Hit. You now have a 16% chance to miss against bosses, increasing your damage up to 84,000 damage. This is -16% damage.

As you can see, 1% spell hit increases damage by the same amount of damage Fireball hits for. 1,000/100,000 is equal to 0.01, which is 1%. Therefore, 1% Spell Hit = 1% increase in damage.

Maths
Assume you specced 10/48/3 and you are in a raid trying to do maximum DPS:

Improved Fireball will cause your Fireball to receive 87% of +damage
Empowered Fireball will add 15% +damage
Playing with Fire increases damage done by 3%
Fire Power increases damage done by 10%
Improved Scorch stacked 5 times will increase damage done by 15%
Ignite causes crits to hit for 210% normal damage (150% + 40%*150%)

Giving

A total of +102% damage coefficient
A total of +28% damage.
Massive criticals

The below table shows the amount of damage Fireball does at different damage amounts with the above conditions, ignoring Fireball DoT:

+dmg	Fireball Damage	Fireball Crit inc. Ignite	Avg dmg (20% crit)
0	1043.2	2190.72	1272.704
200	1304.32	2739.072	1591.2704
400	1565.44	3287.424	1909.8368
600	1826.56	3835.776	2228.4032
800	2087.68	4384.128	2546.9696
1000	2348.8	4932.48	2865.536

This table shows the amount of damage +1% hit is equal to at different amounts of +damage.

+dmg	Avg dmg (20% crit)	+12.62 spell hit equivalent
0	1272.704	12.73 damage
200	1591.2704	15.91 damage
400	1909.8368	19.10 damage
600	2228.4032	22.28 damage
800	2546.9696	25.47 damage
1000	2865.536	28.66 damage

Conclusion
This shows that, at +0 damage, with the conditions mentioned above (10/48/3, 5 stacked scorches), 1 spell hit rating is approximately equal to 1.03 spell damage (1.01*102%).

At +600 damage, which is easily obtained with blues, 1 spell hit rating is approximately equal to 1.8 spell damage (1.77*102%).

At +1000 damage, which should be the amount of damage obtained from SSC/TK epics, 1 spell hit rating is approximately equal to 2.31 spell damage (2.27*102%).

Comparing the two gems +9 damage and +8 spell hit at +600 damage. Since 1 spell hit rating at +600 damage is 1.8 spell damage, the +8 spell hit gem would give +14.4 damage. 14.4 is bigger than 9.18

In conclusion, stacking +spell hit will give the highest DPS increase for boss fights until you reach the +spell hit cap at 16%, or 202.24 spell hit rating (164.32 spell hit rating for 10/48/3).

As a Shadow Priest you should be socketing all your PVE-gear with these. You should have the +hit cap with talents, a bit of hit gear and a hit trinket (Starkillers Bauble, Scryer's Bloodgem, Arcanist Stone, etc)so the spell damage gems are perfect.
