Im curious, why nobody uses a quad Black-White-Orange-Red Gem for Mana Farming. And a (either white or black) Red-Blue before the Mana-Gem for the extra slow.
I know, that its additative. But with a quad-gem with double bounds, its clearly stronger than a simple bloodbound.
Here a Orange-Black-Red gem (g40):
Damage: 28,811,796,220 - 198,870,515,225 (tough its not relevant for a mana-farming-gem) Shots/Seconds: 588.11
Chain-hit: 260.71 hit length Mana-Leech: 323,325,730.89 mana/hit Bloodbound: x98.25
compared to a Orange-Black-White-Red gem (g40):
Damage: 45,861,196,120 - 304,364,630,734 (tough its not relevant for a mana-farming-gem) Shots/Seconds: 612.13
Oh... i forgot something important. The poolbound doesnt rly scale well at later grades. I've just seen, that a g42 has only 2.x lower poolbound than g45. While bloodbound rises extremly high with each grade.
Here is a G60 difference The 8760 Hit is showing the difference after 60 step from a mana farm A regular mana farm has far more monsters that this example Mana Farm gem usually have 1b Hits and around 10000 monsters on it. Poolbound skill is not enough to supply a good multiplier to the gem That's why we will not choose GROB.
Why Quad gem with "Slow"? Slow can have a full skill (90% with 12.5sec) within G12. After that, (Blood)bound skills can hold the slow skill to a high level. Why not other skills? It is because other skills in a mana farm is useless (Armor Tearing, Poison etc.)
Why not double trap? Double Trap slows a monster early that it doesn't touch the mana farm. ORBS [Slow;Blue] can slow a monster and provide a good number of mana.
What is the combination of this example gems 1O1R2B Till G15 ; 1O1B Till G60; 1O1R1B1W Till G15 ; 2O1B1W Till G60
