How do I max out my health/stamina/dead eye rings?

[Foxtrot]

For a long time now, all of my outer rings are stuck at level 8. I know the events of the later chapters affect core drain, but does that stop me getting max stats?

Do I need all the trinkets to max out, or something else?

You Need to do all the challanges, and then go to the trapper and buy the reinforced Equipment that you get from this.

So each set of reinforced equipment purchased gives me more for the rings? I thought that simply using a set of reinforced gear upped the stats and the others were just for style...

You can read it here , Dead Eye as an example: Earn bonus Dead Eye unlocking Special Equipment, witch gained from Challanges.

Thanks, yes I know that some kit gives me perks in terms of increased stats. 

So the trapper has a range of different reinforced bandoliers. Does buying every style of reinforced bandolier give me a bonus, or do I only need to buy one style to get my increase?

When youre shopping at the trapper, the description of the various sets tells what they do. For example, Bandit says "Stamina bonus: Buy the complete bandit set. Additional Stamina Bonus: Buy the complete bandit, gambler & master hunter sets."
