This list of mods focuses on making a mage-filled party more interesting while also removing some of the annoyances I find with Divinity: Original Sin 2. Later, with testing, I will add mods that balance the game around more hybrid-focused physical/magic builds - hoping to achieve a balance between the party that Larian did not.

I currently recommend playing this list on at least tactician, and even that (especially with 5 characters) can be too easy sometimes. I hope to add mods to this list soon such as level enemies to current level, reduced XP, and the Armor and saving throws reworks.

Basic load order stuff:
Odinblade's Pyrokinetic add-on goes after Odinblade's pyrokinetic overhaul
Chronomancer (magic) goes after the Chronomancer class
make sure combat luck comes before combat luck + containers
Enhanced talents and then
Divine Talents comes at the last of the load order
