Logic is that hero only skills should have bigger modifiers than skills that have effect on whole army. So I increased them if you wanna go stronger Hero path, because army support skills are already strong.. I aimed to make balanced skills, not OP (theres some other mods that do that)

Changes (if not listed, rest of the effects are default values in same skill):

Fighting I now gives +15% damage
Fighting II now gives +15% damage
Archery I now gives +20% accuracy (specially useful if u have my Increased Range mod enabled)
Archery II now gives +20% accuracy
Martial expertise now gives +20% damage
Defense I now gives +2 armor
Defense II now gives +2 armor
Magecraft I now ignores 2 resistance
Magecraft II now ignores 3 resistance
Distant Evocation now adds +2 magic range
Arcane Strength now gives +20% magic damage
Resistance I now gives +2 resistance
Resistance II now gives +2 resistance
Resistance III now gives +3 resistance
Restore now heals 20 HP
Inspiring Leader now reduces upkeep -30%
each Vigor skill now gives +20 hero HP

should be compatible with all other mods that dont change exactly the same properties.

unzip file to your "\Documents\Paradox Interactive\Age of Wonders 4\Mods" folder (create one if u dont have)

enable mods in your AOW4 launcher (dowser.exe in game folder)
> playset
> add new playset
> check the "hero skills" mod name and play.
if you have more mods, add "hero skills" to your existing playset

due to more extensive changes to hero skills I recommend starting new game :)

compatible with Expanded Hero Traits and others mods that just add skills.
