Each time you upgrade that Calibur, you'll have the option to either keep the current UV, or try rolling for a new one. But if you choose not to keep the current UV, you may wind up with a completely different UV, or most likely no UV at all. Players who are trying for good UV gear will generally make a large quantity of the lowest level item (the 2* Calibur, in this case) until they get a UV they like, and then upgrade the "keeper". There is no mechanism in the game at present for upgrading the UV on an item.

As for Heat, it's evenly distributed among all equipped items that are less than level 10. Needless to say, if you're trying to level 5 items at once, it will take 5 times as long if you're only leveling one.

Score! Thanks man, this is just what I've needed for a while.

I personally would HIGHLY recommend a Nightblade and further upgrades to it. It does half normal damage and half shadow damage. The key is that slimes are weak to shadow damage and thus, the blade crits them. Any newer player is likely going to go through the slime kingdom countless number of times, and this blade pays off in spades so long as you do so.

One question: I'm a newbie, using my energy to craft haze bombs are a good option to make money?

Is there any merit to the Autogun lines? I'm currently T2, and I'm trying to upgrade my own. Is it worth the effort, or should I just go for an Alchemer?

Also, am I better off crafting my own items, or buying them?

@Pika_power - Most people aren't too high on the Autogun. I haven't played with anyone in T2 or T3 that uses it. I have one that I occasionally use as a just-for-fun gun in T1 and will eventually upgrade through the Needle Shot line, but I have other higher prioties. For me, it looks cool, but when I want to go on a serious run I leave it behind. But, don't forget to have fun with this game. Some posters will tell you how terrible a weapon/armor is, but you know what, if you're having fun, then who cares?

For the most part, you're better of crafting your own items, but it's a matter of time. For crafting, you have to obtain all of the materials and there's an energy cost, but you can craft as many times as you want (as long as you have the resources) and sell what you don't want at the auction house. But, if you want something now (don't want to spend the time to do dungeon runs to obtain the crowns and materials) then buying is the best option. I usually craft, but occasionally I buy. I bought my magic cloak with med curse UV for only 5K crowns at the AH, a great deal! And on days when I don't play I craft 2 2* items with my ME and sell at AH so I make money even when I'm not playing.

This looks like a good place I could ask a question.

Should I keep my Owlite shield and upgrade it to 3, 4 and 5 stars, or should I buy and upgrade the Bristling Buckler instead? What do you think will be better?

@Kerma
The calibur is a fantastic weapon all the way up until 5*. I would recommend it to anyone, i'm currently working on a divine avenger but will always use the calibur line. It has a brilliant charge attack and can hit everything for good damage. it's not just a "newbie" weapon, it can be used anywhere effectively.

Also, I would recommend going from Wolver -> Vog Cub because fire resistance is a must for the higher tiers in my opinion.

Is there a recommendation on which line to take the calibur at 4* and 5*? I figured just the Leviathan since it would be multipurpose whereas the Vanquisher is more undead damage. Which would be best for just a beginner player not spending money for energy (so probably won't be getting multiple gear of any sort for a very long time lol)?
