Re: Javazon question
Agreed.
You'll want the poison skills (both) maxed.
Then I'd max CS. As for it's synergy. . .it's a toss up. Some say LF. . .and that's a good road to take.
Personally, I don't go with LF, I go LS for the Chain Lightning, but that's just me.
You can go with any of the synergies you want actually, but you probably will want a skill that you can fall back on.
And we all know what a gem that LF can be on Cows and other packs of non-LI monsters.
