Currently, nearly all of my gear (and I have a lot of weapons) is 4* with only two 3*s (Twisted Targe and Prismatech Alchemer Mk II). Although I have only one armor set, I do not plan to get more until I get some 5*s. Personally, I feel that I have enough good equipment and want to upgrade one of my 4*s to a 5*.
Here is a list of my equipment:
Swords
Ascended Calibur
Avenger
Faust
Silent Nightblade
Dark Thorn Blade
Blzebrand
Guns
Gigawatt Pulsar
Strike Needle
Shadow Driver
Prismatech Alchemer Mk II (out of discussion)
Bombs
Electron Bomb
Radiant Sun Shards (out of discussion)
Freezing Atomizer
Armor and Helmet
Ash Tail set
Shield
Blackened Crest
Wise Owlite Shield
Twisted Targe (out of discussion)
In my opinion I should upgrade either one of my weapons or one piece of Ash Tail. I do not think it is practical for me to upgrade Ascended Calibur to Leviathan Blade since I plan on having 3 weapon slots always and I normally do not bring bombs so I am free to bring my Gigawatt + 2 of Avenger/Dark Thorn Blade/Blazebrand/Silent Nightblade/Faust. I think I should either get one piece of Ash Tail to Vog Cub or upgrade one of my swords (I am thinking of Avenger). What do you guys think?
By the way, I normally do either FSC or RJP and I am planning to do FSC more than RJP.
Ordinarily I'd recommend that you upgrade your weapons first, because Tier 3 is more about offense than defense. However, you don't have any elemental armor. So how about you upgrade one piece of Ash Tail to Vog Cub? Then you have some elemental and fire protection. This makes gun puppies and FSC easier. After that, upgrade your most-used weapons?
