Cloth/Leather armor is similar in defensive capabilities - if you want a "medium" armor you'll need a moderate str score instead of dex.

Example - let's say you're level 10, chances are you can find cloth armor with 20 points of defence on it, leather would be about the same, scale armor would be 32 and then plate would be around 40.
The robes would require int 10, leather needing dex 10, scale would only need str 8 or 9 while the plate needs 11-12.

As for weapons - Daggers are dex, Bows/Crossbows are dex, Other 1 or 2 handed weapons are strength except staves, which are int.

Tbh I wouldn't recommend trying to recreate something you've played in another game here because you'll disappoint yourself - focus on playing this game and not some WoW or DnD character, you'll have a better time.
