About bombs thanks for the recommendation of the different types of bombs, I am thinking about crafting a new set only for bombing as imo using bombs with bad CTR are really hard to use while battling monsters especially Arenas.

This is why you should consider saving up 150k crowns and buying a 2* bomb you want to craft up to 5* that has a CTR Med UV on it. It's worth it in the long run because 150k (price may vary a bit depending on bomb and I've been inactive for quite some time so I'm not up to speed with current market price for UVs) is cheap when compared to the cost of heating up a 5* item to level 10. Having CTR Med will make your bombs have CTR VH by default at level 10. That will let you avoid chaos armor's bad status resist, or save you having to get trinkets for bombs. Just makes your bombs a lot more versatile, because you'll be able to bring them in your non-bomber loadouts as well. For example having a Status haze bomb or an electron vortex as a side weapon in your sword/gunner loadouts. Definitely buy the UV from other players, don't try to punch it yourself. Punching is riskier since it's not unthinkable that you won't get the CTR UV that you want in 7-8 tries (which would cost you 140-160k crowns).

Yea, getting chaos is probably the best idea for you because it can power your blitz needle, combuster and shiver all at once, making for a very tidy starting FSC loadout. Since you're nervous about the status weakness, I'd recommend seerus's mask via Operation Crimson Hammer, as that would buff your blitz to max ctr without you having to UV it as well as provide fire and shock resistances, which are key. You could also get one piece of vog to pair with chaos, or full vog if you plan on getting CTR uvs on your bombs, though chaos is just too good.

Later on you'd want to look into dark briar barrage and dark retribution, because that combination will let you handle Dreams an Nightmares which will let you in turn heat your gear up.

Yes Hagekobing,

A weapon gets a standard CTR Low at heat level 5, and that goes up to Medium at heat level 10. So if you start off with a CTR Med UV, it will add up to CTR VH when you finally max out the weapon at 5 stars level 10. Then you can still equip a piece of chaos armor or a bomb CTR tinket if you want to max it out (+6 CTR). Alternatively, you can stick with the +4 CTR which is already pretty good and focus your trinkets/armor on other things.

The thing is, many players ignore UVs until they get to the late game, leaving them with many 5 star weapons that have no UVs but took a lot of effort to heat up (because radiant fire crystals are so hard to get). At that point, you have to turn to Punch (the UV NPC) to get them, and it's likely that you'll end up spending more Crowns. In the end, you only have limited equipment slots to work with. UVs allow you to get boosts outside the standard slots, so in the end you'll be more comfortable and flexible in creating your loadouts. You can easily side in a voltaic tempest with a CTR med UV in your sword loadout, it'll charge up fast enough. If you have a Voltaic tempest without the UV, you'll only be able to comfortably use it in your bomber focused loadouts or when using chaos armor, which comes with the cost of lower defense.

3200 CE for 3 very good items is a very good trade. I would start saving as soon as possible for it, or if you ever plan to pay money to the game to buy OCH with said money. It's the best value proposition in Spiral Knights, especially since you want to go swords + bombs.

I would also not suggest setting aside chaos for later, because you want to be a bomber and chaos is what will make that dream come true for you, and if you simply must avoid it, go volcanic demo set-- swords are useable without ASI; asi is just the icing on the cake. Bombs are borderline not useable, or at least much much much worse, without any CTR. Chaos solves all of these issues and makes all of your weapons useable to their fullest-- something that vog simply cannot accomplish.
