Questions about eth titans and others?

[Peanut Butter is nice]

What is it, and how do you get it?
How do you 'upgrade it?'
Also, how much dmg does your LF do?
What are the main killing skills of a pure lightning zon and their synergies? Is it possible to not have to put any in the poison jav skills?
Should I put one point in each passive skill or are some unnecessary?
How can I stop me running out of mana after spamming LF?

Thanks. =)

you find an normal eth titans (monsters drop it yes)
you use the recipe to upgrade weapons (only works on ladder)
and there you go, one eth upg titans ;)

dont know the exact dmg, it depends on the weapon, skills, equip,...

its better to put some points in those passive skills, at least one, dodge can be handy

running out of mana: try get some mana leech on your items ;)

Put points in passives. Just 1, but put them there. Dodge/avoid/evade/pen/pierce/critstrike all very handy. I like a valk too though and I usually put 15-20 in there, but that's my preference. Look up titans and the cube recipe on arreat summit.

Main crowd killer LF (Lightning Fury)
Main Single target/boss killer CS (charged strike)
after passives put the rest in synergies for LF/CS

No you don't need poison skills.
