Alright here is some knowledge that i know.
First get your legendaries first or just use mystica set if u still new. And then craft legendaries slowly.
1. Ghast -2pcs - a must. so OP for melee. you will notice a big dps differ.
2. Armilliaran - 3pcs.
3. Fang of Titanus 4pcs - ( for new player you prolly wont be able to get this since it can only be rerolled on Legendary( not the crafted one)
Sub Plague Descent 3pcs. Until u can get Fang of Tits 4pcs.
4. Bloodthirst - 3pcs. Ideally Bloodthirst on Ring and Pedant...
5. Arcane or Torture - Either one is good. I like Arcane seem to proc a lot. and the aoe dmgd and heals is nice.
note: Skip the two-mind set. itsnt worth it.
Skills and Runes
1. Death Gaze -
2. Deadly Forge
5. magnum Spike - Fang's Buff ( increase crit to party)
6. Anvil drop
7. Flaming sigil
10. Normal atk (spam between skills)
Max all the runes skill you use to 40's
then work your way up to lvl 60, on tempest duration tempest dmgd, and normal atk %.
Stats on Gears
Double stats is what you want to aim for first.
STR,Crit,VIT,SPirit is a Plus on the Double stats rolls.
ATK DIAMONDS with CRITS
DEF/SDEF - Hit Rating
HP - with Dodge
work on what you need.
If your DPs is weak . work on Agility and Swiftness. (swiftness aux give up to 2.5% each ) swiftness give 1Stats to all each upgrade as well.
if your are too squishy work on Flourish. Parry helps a lot.
