I've been scouring the mod lists here and on Nexus, but I haven't found any mods that change gameplay to represent DnD 5th Edition or 3.5 mechanics. I've been experimenting with in-game stats and have come up with a compromise for melee (using dodge as AC and reducing Accuracy to base 50%, with each 5% accuracy adding +1 Hit and each 5% dodge adding +1 AC. All weapons damage changed to match DnD weapons, e.g., Daggers 1-4 damage, etc.), but spells pose the biggest issue.

Has anyone found or made a mod that is closest to the DnD system?
