How can I increase my maximum Health, Stamina and Dead Eye?

Solution 1:

The three attributes are leveled separately. The best way to level these is by completing challenges (see below for more info).

You can view your current level under Pause Menu – Player – Your Character – Health, Stamina, Dead Eye. Click each attribute and check under “Progression” to see your level and XP to the next level up.

Required XP per Level:

• Level 1 = 0 XP
• Level 2 = 50 XP
• Level 3 = 100 XP
• Level 4 = 200 XP
• Level 5 = 350 XP
• Level 6 = 550 XP
• Level 7 = 800 XP
• Level 8 = 1100 XP

Doing all Challenges gives you 1425 XP per attribute, enough to reach Level 8. That’s where XP progression stops but you can actually bring them to level 10 via outfit sets. The way this works is that every challenge category unlocks a piece of a clothing set after challenge 1, 3, 7, 10. So completing all challenges in a category gets you a complete set consisting of 4 pieces. Equipping all 4 parts grants you +1 skill bar on the attribute (=level 9). Doing ALL 9 challenges (90 tasks) then unlocks another skill bar (=level 10).
