Yeah, sounds like you're looking for a troika or sealed sword then lots of Attack Speed Increase. It is rather difficult to get a lot of ASI without going full Vog Cub, which you'll have to wait till 5 star to achieve. In the mean time though, you can craft a Swiftstrike Buckler which has ASI High (1/2 of the way to max) but it is only 3* and cannot be upgraded.

If you get the Troika you are going to want the Swiftstrike buckler like Culture said. It makes a huge difference. Get ready for a learning curve too, the 2 swing swords are very different from the 3 bangers. You may want to go ahead and grab an Elite Quick Strike Module too, Krogmo coins are easy to earn or by the Mod Calibrators from the AH. No recipe searching, you just have to come up with the mats, crowns, and ce.

Also, just go ahead and plan on abandoning your Troika after you get your hands on a Sealed sword (3* precursor to DA/GF). Unless the Troika line gets some serious balancing I would not recommend taking to 4* or 5*. I have a fully heated Troika that I used to like to mess around with in T2 (backed up with Swiftstrike & module), but sadly I doubt that I will ever upgrade it. The Troika's 5* just doesn't stack up against the other 5* swords.

There is a bunch of info there, but if you don't learn anything else from that tread, learn this. Shield cancel. This is a big deal and also applies to fast swords. The Troika animation for the first swing goes on for much longer then needed & can be stopped by shielding. This will let you get out faster first swing attacks & stay protected. Another thing I really like to do with 2 swingers is to deliberately whiff my first swing away from the enemies, then turn 180 degrees and connect with my second swing. This way you do more damage and knock them back out of attack range so you are safe to set up another hit. One more thought. Be warned the Troika's charge attack takes years & will leave you very exposed to taking free hits from enemies that you miss with the charge attack. The Troika's charge attack is pretty terrible, takes too long and at the 5* level is weak compared to other 5* charges.

Big and fast sword, huh? Use the Spur series. Upgrade it to the Winmillion and master it. If you need any help in using one, PM me and I'll show you how to use it effectively. Don't go for the cruddy easy way route by using a DA or FA.

Bluescreen, I enjoy your posts. Ima send you a friend request ingame if that's alright with you. haha

My Steam has just crapped out on me though, trying to get some support from the forums to fix it. I'll get at you when it's running again.

Mkay, done being off topic now. haha

big and fast?

get a sealed sword.

don't buy it, but get it from tokens

upgrade along avenger line

it's easy to learn, and ppl love it in T2 and T3. it will serve you well.

Quite a lot of 5* swords end up being big...

The DA and GF line are some extremely useful weaponry. unfortuneately, they have a high learning curve from the proto sword.
The leviathan blade is a good, balanced, weapon. its big, and the same speed as your proto. low learning curve.
The winmillion series could possibly be the best weapon in the game, but if you dont use it right, your gonna start saying F*** u wolvers wont get hit by my sword@! unfortunetely, it onlys goes to 4*
Troika series is like the DA and Gf, only normal damage.
Brandish lines are like leviathan blade.

A good shield with the calibur would be any shield. grey owlite, dread skelly, dark thorn, etc.
