Bloodbath of the Heavy Metal Necro

I show you the power of the Heavy/Dark Metal Necro. It's quite a fun class to use. I didn't farm for it instead I did Pay2Win, heh. But it's probably worth it to farm for Dark Metal Necro.
I kill the Ultra Blood Titan in 3 minutes and 21 seconds; I don't know if that is good or not but whatever. I probably suck.
For the skill combo sequence I go with 2, 5, 3 and then 4. If the monster deals too much damage I usually stop using 5 and just use 2, 3 and then 4 until Dark Pact fades so I don't get killed.
