My Pet Verdruss have this Stats: Level: 17 Strength: 54 Defense: 63 Health: 14/14 Speed: 57 -- but i can train only Lev. and Healt. I have Pets higher and lower and they have more Options, what is happend here? I no find any Info so i beg for a Tip.

From training page "You may train each stat up to 2.5 times your pet's current level." So, 17x2,5 = 43 Stats other that health are higher than that. You'll be able to train them after increasing level.

Mmmh, my Pet Traumfaenger is on lev. 20, so that means the next Stats come on Lev. 50 ? 20 x 2,5 =50. But he have :

Level: 20 Strength: 18 Defense: 15 Health: 10/10 Speed: 10

That confused me, cause i have read the same you wrote. The Lev. is higher but the Stats are lower. !?

No. On level 17 you can have each stat at 43. For Verdruss Strength: 54 - higher than 43, can't train Defense: 63 - higher than 43, can't train Health: 14/14 -lower than 43, can train Speed: 57 - higher than 43, can't train

For Traumfaenger, level 20, stats can go to 50 Strength: 18 - lower than 50, can train Defense: 15 - lower than 50, can train Health: 10/10 - lower than 50, can train Speed: 10 - lower than 50, can train
