I'm almost finished with my first 5* loadout, which is entirely for FSC.
Divine Avenger
Argent Peacemaker
Vog Cub Coat
Vog Cub Cap
Barbarous Thorn Shield
Elite Slash Module x2
Assuming I used this same loadout for all four of the available Danger Missions (saving my future orbs for very specific things, namely a Gunslinger loadout), how hard would they be to run solo? My experience with them in T2 was pretty grim, and I'm not sure if it's because I need to improve, or if they really are intended to be done with a full party and not solo.
I at least want to get good enough to be able to run them without having to burn a jackpot of Life Sparks to get through them.
The answer is...It really depends!
Anyway, you cannot do them with those weapons. Pure elemental is baa-aad news. (When did I turn sheep?)
Do you have any UVs? Are you bringing a Sprite?
I would personally have wanted some Shadow resist, since Elemental monsters aren't nearly as deadly as the Shadow ones. (Also, Shadow shows up in 3 of the Danger Missions, while Piercing is in 2 of them and Elemental is in another 2.)
Finally, yes, some of them are much better in a party. I find the Freeze-themed one to be impossible without a party, due to how freeze works. C42, though, is easier solo since that mission is already so chaotic. (And you have a better chance of causing flinch when you're alone.) The other two are more up to preference, but most like to go in parties.
