Ok, just noticed based on cost that somehow, I'd not gotten five of the gems in the control upgrade.
A HL0 dupe of the current killgem (the one that was Quad but trned Triple when I squeezed the W out) is :
Grade 50
388,169,271,925,430-8,451,450,461,096,004 damage
x55,018,620,671.56 crit damage
331 chain hit
x77.17 bloodbound
damage rating : 464,987,147,038,789,086,989,898,684 (4.6e26)
A fresh control (triple gem only)
490,846,252,277,475-10,546,715,297,151,698 damage
x85,743,800,437.84 crit damage
388.95 chain
x96.21 bloodbound
damage rating : 904,315,451,704,830,347,827,692,026 (9.0e26)
As you can see, its still a loss of about half the damage rating on this killgem.
And for what its worth, I just Dupe'd the manafarm gem. Sitting in the gembox, it is :
Grade 50
372,556,779,328,954-6,935,866,640,578,032 damage
320.49 chain
95,266,640,699.26 mana/hit
x73.43 bloodbound (HL1)
A triple gem for comparison purposes:
Grade 50
462,879,895,478,108-8,653,456,520,250,462 damage
375.85 chain
148,448,709,803.7 mana/hit
x91.54 bloodbound
The managem and killgem are still classified as Quad Gems. That means that, despite losing the W as a modifier, they are still subject to the same mods that Quad gems are : +220% damage, 120% specials power. Triple gems, on the other hand, are +220% damage, 150% specials power.
Doing the math on the Bloodbound special, that is almost exactly the difference between the two gems. Factoring in the bloodbound multiplier, that is almost exactly the difference between the two gems' mana leech as well.
Anyone think that W is still a viable thing to use in their manafarming gems? Because I don't. Sure, it started off real strong compared to nothing but B .. but even after it got stripped from the effects list, it still hampers the gem by quite a lot. It may be worthwhile starting off with the lone W, but if you do, around grade 30, replace that gem with one that never had the W to begin with. Start farming the hits so your Hit Level is good enough that the replacement gem is an automatic upgrade.
