Sword: Final Flourish; I love the enormous range, speed, and mobility it has. The charge is a lot more fun to use than the one on the BTB.

Gun: Magma (or any other) Driver; setting up ricochets and aiming is a big part of using this weapon, and getting good at it pays off big time. I really enjoy weapons that have that high potential.

Bomb: I'm not a big fan of bombs, they feel really clumsy and I would rather not occupy my limited weapon slots with a utility item. Voltaic Tempest is pretty cool, though.

Electron Vortex for me, hands down.
Nothing is more fun for me than seeing heat and crowns suddenly appear en masse after wiping out
most of an arena wave in the vortex.

Bombs:nitro,RSS and ash of agni.
i love exploding things,sniping and i am pyromaniac.
just kidding.
Full bomber FTW!

Pure enjoyment purposes?

Rss and callahan. Not extremely effective, but fun.

Huh. Thats a good question. My top 5 things I've crafted-

Biohazard/Neutralizer. Its far more complicated than you think, and there is no spam involved, unless you want to compromise DPS. All boolets start at north, and travel counter clockwise. Explosions occur on the circling charge, not the center of the target. Lots of timing, lots of challenge. DPS is also interesting with healers- the more initial charges you have on, the more damage is saved by letting the healer do nothing.

Stagger Storm. Its strangely hard to use, and doesn't do anything too useful in the clockworks- but once you get used to it, you can walk through huge crowds easier, and keep it up constantly.... allowing you to continue to stun things. The minute you leave, it gets dangerous- if you're with a team, they'll benefit greatly from your status though. More so than shock or fire or poison or frost in many cases. BSSHHOONNGGGGG

Radiant Sun Shards. The dual damage makes it deal good damage to everything in FSC except the few slimes/turrets/beasts, and its bonus vs fiends makes it kill trolljams easily- its fun bating them onto it. When used with electron vortex, you can deal 4 times the damage by pulling everything in and then dropping it- a dangerous maneuver. And there is nothing more satisfying than watching 15 kat/grievers die at once.

Volcanic Pepperbox (Post Nerf). Fighting mecha knights is hilarious. They rush up to you, disabling their ability to shield, and then get hit full on by a charge that shoots them across the map. All of them. Pushing things away doesn't deal as much damage, but you can still kill lumbers, slimes and turrets with ease.

Brandish lines. They kill, and they kill well. They're easy to use, and they deal a ton of damage quickly, meaning that they supplement any gun or bomb greatly, for any applicable stratum (eg. not a fiend/beast stratum). They're cheap as well, and great for bosses. Probably the first weapon you should get, unless you just have something against swords.

Well it's glacius for me.

When u charge u can escape the enemies LOL

I'd have to say hands down, the Rocket Hammer is the most fun sword to use, and are very useful in situations such as FSC, where it is easy to skate around trojans, but still have the benefit of elemental damage.

Other than that sword, I find that the Wild Hunting blade is fun to use, because who wouldn't want giant wolvers coming out and biting the crap out of stuff while you hit it.

Guns aren't much my style, but they can be used to fool around with. The inner bomber in me likes the Pulsar series, because its a gun that explodes. Who wouldn't want an exploding bullet gun. For that reason, the other favorite of mine is the catalyzer series. Because 1 shotting lumbers and almost everything around it is fun too.

For bombs, Dark Retrobution has to be the most fun by far I've had, however I don't really like when everyone uses it. It requires you to gauge kiting, much like nitro, but its shiny.

I also like Radiant Sun Shards. When I was a much younger knight, I thought it wasn't very good, but when I played with it, and found out how easily it kills zombies, it became a bomb that I almost always have on me at all times. It requires some skill to use effectively, but even if its not placed properly theres still a bunch of shiny stuff that pops out.

The Warmaster Rocket Hammer is the most fun weapon to use (for me). It is only really practical vs a single target & even better if that target is stationary otherwise it is outdamaged by Brandishes. It is just really fun to use & takes some care to use around hazards. Plus, I barely walk anymore... I just rocket charge everywhere (note not really any faster then just walking due to the pause in forward motion of the first swing).

My Vile Striker

On my first craft, I got a gremlin very high UV. I can't put the thing down, especially with the new Ex pack.
