I wouldn't say that aiming for Defense in SK is a bad idea, Juances.

Aiming for Defense and expecting to tank everything, however, is, so even if one goes for pure defenses common sense should still be exercised (read: dodge when you can and you will be a happy man).

@ the OP:

As far as pure defenses go, the Jelly/Magic/Skelly set endpoints are your best bet, and you should focus your efforts on knowing how the heck to use your weapons safely -- because nothing says 'bad day' like attacking at just the right time for that Lumber to not get stunned out of its swing and therefore you get to kiss pavement.

If you're not really going for PURE defenses, if a swordsman build up a Skolver Set to go along with your Vog Cub and get to work on Skelly gear or a Deadshot set so that you aren't caught with your pants down in areas where you need Shadow DEF until you can get your mitts on the Snarbolax Set (which of course will take a while).

Beyond that, though, again: While you build up your defenses, make sure to not forget your evasion -- the most painless hit is the one that misses.

Warrior-Iguy, your proposed loadout (Vog Cub, Vog Cub, Grey Owlite, DA, FF, Umbra, Polaris) is reasonable. But I agree with the others here who are recommending that you get some shadow armor. The monsters that deal shadow (fiends, undead) include many of the nastiest monsters in the game. And, since you seem to be pretty evenly split between swording and gunning, one piece of Vog Cub and one piece of Shadowsun seems great to me. That's what I would get first, anyway.

Your original post already contains the key insight to your loadout: Your fourth weapon is primarily for crowd-control rather than damage. Polaris is good for crowd-control, and good against knockback-resistant targets such as turrets. For other uses, there are better elemental guns. My favorite is Nova Driver, although I also like Storm Driver (for shock) and Argent Peacemaker (for ease of use). Consider also Voltaic Tempest.

Really, any three of your four proposed weapons would make a decent loadout. So don't fret the details much more right now. Try it out and reevaluate later. Enjoy.

If you're undecided about your support bomb choice, here's some things to consider, hopefully help you out:

Shiver works well with anything, and is good for sword attacks (esp. solo) for letting you take your time and pick enemies off.
VT is a bit riskier as they continue to move, but the shock damages, spreads and interrupts, which is great but allows retaliation much easier. Also, your polaris can spread shock just as easier, with some safe KBing.
VV is a vastly underrated bomb, although it's better utilised in parties. If you can get a group of them poisoned them drop on any wide attack (DA charge, polaris spams, Umbra charges etc) you'll kill faster than you even realise.

Don't forget to consider AoA and SS, as AoA can deal crazy DoTs and SS gives you all the time you need to act, especially with the slow swords (although will require attention to stun bug).

In your situation, personally I'd go with shiver, as that's what I use with my hybrid loadout for reasons above.

@Bopp/Warrior-Iguy:
Fair point; I probably should have mentioned that for all the benefits of shiver, it has to be group-compatible (depending on how your group plays) or it could potentially cause even more problems than not, in which case the other options could be much better.

@Warrior-Iguy:
Oh also, vortexes are a good support bomb option, and work nicely in group play for most playstyles and weapon choices (allowing group gankage of a bunch of baddies at once), just in case you hadn't considered it.

In terms of "good dodging armor" I would say to go for mercurial armor (gives movement speed increase) or for ASI armors, like vog and justifier. ASI will let you move a bit more as well...

If (There are mendors && your party knows about poison) venom veilor > Ash of Agni; else Ash of Agni > venom veilor;
