I have no idea whether to choose trinkets holding CTR medium or go old fasion and bring some volcanic armor/mad bomber suit for FSC runs with a shivermist and radiant sun shards, and I need ideas to bring.
Shivermist has no UVs, same with radiant sun shards
If you're using only status-giving bombs, such as Shivermist Buster, then you just want CTR Max! But if you're also using damage bombs, such as RSS, then you also want damage bonus Max! You can get these bonuses from UVs, armor, and trinkets. You don't have UVs. So you need to use both armor and trinkets.
Two Mad Bomber pieces and one trinket will suffice. One Mad Bomber piece, one Volcanic piece, and two trinkets will suffice.
