if you create you own equip, you can get UVs (improvements), if you are lucky.

dont just buy it, it destroys your fun.

Pure bomb is difficult because there are many situations where its easier to have a sword with you (breaking blocks is one of them, killing a single lone enemy is another) I would recommend carrying a calibur with you for bombing.

jelly king palace levels 15 and 16 are very profitable, and easy to bomb in. Currently the trip to JKP will put you up against dangerous alpha wolvers though, so be prepared.

A 4* fire bomb should be your first investment. It will let you rip through JKP easily and efficiently, and is also good for arenas.

Once you can solo JKP you can easily make back the CE you spend going there and then some with just the cash drops, sell the materials and its very profitable

Use the AH to buy two pieces of low fire UV spiral bomber. The reason for this is because if you upgrade this to one piece of mad bomber (armor) and one pierce of volcanic demo (helmet) the twin low UVs will be 'enough' fire resist to counter the one piece of mad bomber (ignore what the resist bar says, it lies). More is wasted. This will give you VH CTR and med damage boost, allowing you to capitalize on high or very high UV damage bonuses on your bombs with out waste.

Damage bonuses on haze bombs only effect the elemental 'blast', not the status effect damage, So getting a high damge bonus to construct or undead (or maybe slime) is a reasonable proposition, but worrying about damage against elemental resistant things is pointless. The good news is a high damage bonus UV haze bomb is only like, ~10k crowns, which is very affordable.

Once you have your 4* fire bomb and 3* other gear you can easily farm JKP. From there you can work on upgrading everything to 4*. Then start colecting other bomb types, and upgrade stuff to 5*, and you are all good and nice and shiny.

Try to remain CE neutral if possible, spend some of the money you make from each run buying the CE back, though you have a nice buffer to work with its a good practice to get into, and CE prices are only going to go up so CE bought today is money saved tomorrow.

Since you bought CE on that account, you can also run another 'free' account now, as its mist energy store will be unlinked from your own. This gives you a crafting alt on the other account that will generate 100 mist energy every 22 hours. Thats 10 haze bomb attempts. CTR on bombs is no good for 'bombers', but non bombers find high/vh ctr haze bombs very desirable since it lets them have a shivermist as a backup weapon, so you craft to sell those (VH are worth quite a bit, auction them in the bazaar forum). Any high or VH UV damage bombs you get you can use for your own collection or sell (150CE for highs, ~500CE for VH, those are the prices i use. I only bother selling construct undead and slime UVs though, the rest i just vendor)

The Owlite line is always good since it gives Elemental defense and Fire resist which you'll want for tier 3.

I would say: Don't be in a rush to use your CE, you will regret it. Using crowns to buy cheap 2* equipment from the Auction House might be ok, though, so that you can quickly try out different weapons/styles. Once you have a good idea what you like, you can try to make your own High-Quality items with your Crystal Energy.

Any 2* item listed at 2,000 crowns or less is a good deal, but that doesn't mean you should buy every 2* item because you will go broke this way.
