Arcane Conquest is all about squeezing out the most DPS that you can with a proper build, upgrades, and cycles. That said, some classes simply have better DPS outputs than others for various scenarios. Here's my Arcane Conquest class tier list .
I'll be ranking all classes across three categories which are best overall damage, best cycle damage, and best support. Each class has its strengths and weaknesses but it's ultimately down to scenarios and your build. That's why I'm assuming you're playing Calamity with best gear, upgrades, and skill trees for these rankings.
The best sustained DPS classes for boss-killing from best to worst are:
The best overall damage classes per cycle (burst) in the game from best to worst are:
Paladins are the best supports in the game because they can both draw aggro well with high HP and heal allies. Also, they can block attacks with shields so always be sure to stand behind your Paladin. Additionally, if you have 2 or more Paladins in a party, be greedier with your build focus on damage, and ignore the Shield (Green) tree.
And that's my Arcane Conquest class tier list. For more Arcane Conquest guides, check out the best skill tree
