Anyways i'm prepping for UIMF and UFSC and here is my intended loadouts for each.
UIMF:
Mask Of Seerus (Stun low, Curse high)
Snarby Coat (Fire max, Shock max)
BTS (elemental low, piercing low)
Bomb CTR Med Trinket
Gun Damage Med Trinket
DA (Slime Med, Fiend Med)
GF (Beast Low)
Polaris (Slime High, CTR VH)
Nitrome
UFSC:
Mask Of Seerus (Stun low, Curse high)
Deadshot Mantle (Fire Max)
CoA (Normal Med)
Gun Damage Med Trinket x2
RWH (Undead High)
Callahan (CTR med, ASI vh)
Polaris (CTR vh, Slime high)
To Be decided later
So any opinions and suggestions for the last spot in the UFSC loadout?
Read the wiki page "Shadow Lair", if you haven't already. I assume you mean Perfect Mask of Seerus?
For SIMF: There is basically no shadow or piercing damage, so some of your choices seem odd to me. You're bringing Snarbolax for the UVs and BTS for the damage bonus? Your weapons are fine, except that your gun is going to set off quicksilvers.
For SFSC: Your armor looks good. Don't worry too much about curse. I assume that you're comfortable with WRH in FSC? (Novices often dash into fire.) Callahan is for Vanaduke? Do you know the weapon well? It's a little less mobile than Polaris or Argent, and you're going to want mobility. For trojans, I really like piercing swords. Blitz Needle is also not a bad idea. Have you considered Voltaic Tempest, Venom Veiler, or Stagger Storm (stun is bugged, I know)?
