Hello Runners,
I did some training and accurately calculated the experience needed for each level.
Strength, Agility, Stamina all have the same experience required.
Hope it helps with your build plans !
Total XP Per level
Level 2 - 80 XP 80
Level 3 - 180 XP 100
Level 4 - 320 XP 140
Level 5 - 470 XP 150
Level 6 - 710 XP 240
Level 7 - 960 XP 250
Level 8 - 1260 XP 300
Level 9 - 1560 XP 300
Level 10- 1860 XP 300
Level 11- 2160 XP 300
Level 12- 2460 XP 300
Level 13- 2760 XP 300
Level 14- 3140 XP 380

Level 16- 4140 XP 500
Level 17- 4640 XP 500

I stopped testing at level 18 but i imagine it requires a further 800Xp for a few more levels.
