Edit: I got feedback from SrkAmt@R2games.s272:
I'm lvl 50 mage. Talent level12. To upgrade to lvl 13, 18000K exp is required while at 15000K exp ur char lvl will upgrade to 51. So the talent cap for lvl 50 is 12.
Edit 2: Got feedback from SrkAmt @ r2games s272 who is a level 54 mage
- lvl 50 - 53 talent cap is 12
- lvl 54 talent cap is 13
