Green looks nice and is easy to read. Yellow and white also look fine to me.

Playing through slowly but finished Act 1.

Progression Levels:
Sparta - 6
Tegea - 8
Megara - 10
Ambrossos - 11
Delphi - 12
Athens - 16
Knossos - 16
Rhakotis - 18

I've found some more bugged gear which occupy a single slot and have no model:
-Telkine Veil
-Tricker's Bow
-Ring of Atus
-Moltenblade
-Emerald Marchers

The Runemaster prefix also doesn't apply the skill bonus to Rune skills. I'll send my save with the bugged items separately.

For feedback on the changes to leveling, I would say that for Act 1 the progression still feels smooth. The difficulty didn't feel much different even with reduced levels. As noted however, the level requirements for souls no longer aligns with the level you encounter the enemies that drop them. For example, Nessu's soul requires level 14 while I fought him around level 7. This issue will probably become more pronounced in Epic and Legendary.

I'm a little disappointed about not being able to enchant Epics/Legendaries. From prior Soulvizier playthroughs I already thought that many of the good affix rolls on Rares and MIs outclassed most uniques. With the changes to resist penalties you can probably just focus on getting good damage rolls on green gear and get resistances from enchantments. That said, I haven't played much with the new Ragnarok/Atlantis content and don't know how well it stacks up compared to IT. I also miss the small quality of life changes such as potion stacking that I believe were previously built in.
