The Infernal Eclipse of Ragnarok modpack has recently gotten an update with a lot of changes. One of the major changes in the update is the change to the Boss Rush event, and good grief, the event is a nightmare to deal with. It's so much harder than it normally is in Calamity, base or add-on, that it's actually ridiculous. While I highly doubt most people would care, I figured that, to those who struggled with the event, it would be nice for me to share what loadout is best for it for each class.

Some notes to address:

1. The Infernal Eclipse modpack for this topic includes these mods:
   * Calamity
      * Calamity Ranger Expansion
      * Calamity Infernum
      * Catalyst
      * Calamity Hunt of the Old God
      * Calamity Wrath of the Gods
      * Clamity (yes, that's the actual name)
   * Thorium
      * Calamity Bard and Healer
      * Thorium Helheim
   * Ragnarok (Calamity + Thorium compatibility)
   * Consolaria
   * Secret of the Shadows
   * You (yes, that's also the actual name)
   * Enchanted Moons
2. Quality of life mods like Fargo's Mutant and Quality of Terraria are factored here.
3. Due to the benefits of Demonshade and Tix-Burnt Ring, hybrid Summoners are also taken into account.
4. Buffs aren't present here because, at this point, you can literally use almost all of them.
5. Catalyst's Auric Tesla armor sets are objectively better than base Calamity's. I just can't find an image of any of those.
6. Exo Sights, the final upgrade to the Eye of Golem, are a viable accessory. Again, I just can't find an image of it.
7. With the Calamity Ranger Expansion add-on, Rangers will use God Slayer Slugs and Auric Bullets for guns (switching ammo is convenient, all thanks to the Planebreaker's Pouch) and Bloodfire Arrows for bows

I think I said enough. Let the image speak for itself.
