Blitz would be fine for Trojans, but trying to blitz and shiver simultaneously would result in a hammer to your face, I suspect.
I don't really see the point of having a normal weapon solely for the sake of the mask stage, though - the damage resistance isn't THAT high.

vog or snarby
bts or almire
enough slash to have max damage and then asi trinkets
DA+polaris or glacius+pacemaker
dread venom
your choice of whatever the hell you like (blitz/toothpick/shards/dbb for trojans or shiv for slags or fov for bigger slags)

My guide to soloing Vana with a Blitz (for someone who hasn't soloed him with one before).

The weapons you need for this setup is Blitz, and a Fang of Vog, and use your main elemental sword for the mask.

I've soloed Vana with a Blitz no deaths, no need to spend half an hour using Polaris, when you can spend a 1/4 of that time using Blitz.

Now, here's the guide.

This works for P1, and P3. You should be able to go without taking a pip of damage if you don't get hit by skellies or the mask.

P1: First of all, kill slags. Then, try to lure Vana to the top left corner. Get him as close to the pillar as possible.
Once you get him close to it, go to the top left corner. Once you get there, go to the very corner, where the pillar should be diagonally lined up with you.
Then, simply blitz vana through the hole. If Vana tries to charge you, or mace you, since his mace has such a wide Area of Effect the pillar blocks the mace hit! Then, just blitz charge him into P2.

Note: This works for P1 and P3. You should be able to go without taking a pip of damage if you don't get hit by skellies or the mask.

P2: Once Vanaduke starts walking to the center randomly, go get some water. Once Vana bends over, throw the water at the mask. Once the mask gets down to the 1, start going for more water. Dodge the bullets and throw some more water on the mask. If you haven't gone into P3 by now repeat.

P3: Repeat P1, there is no difference except shadow fire.

P4: Here is your chance to put out that shadow fire that's been getting around all the field. Once you've done that repeat P2, it will be harder, however. Don't get frustrated and start taking chances.

P5: This is the tricky part. The trick doesn't work because his fireballs will catch you on fire. Get your FoV ready to kill a slag guard right off the bat, it will OHKO it if you position it correctly. Once you do that, kite the other one and unleash another FoV charge. Then, wait for vana to whack his mace, sidestep it, and unleash your Blitz charge. Do that over and over, and if some shadow fire gets in the way a good amount put it out if it's a nag to you.

By following this guide, you should be able to solo vana. You should already be acquainted with using a blitz and where a slag guard spawns. If not, watch one of Exileddread's Vanaduke videos.
After a couple times of doing this correctly you shouldn't have to do this trick to solo him without deaths.

Good luck!
