So I've got 121 CSC I'm sitting on. I bought a 100 CSC Card with SP some time ago, and really have nothing else to spend it on. Would Autotraining Khariklo be worth it? I can only train Level and Speed right now. (That's all that appears in the dropdown menus)

Her stats so far:

Level: 21 Strength: 66 Defense: 60 Speed: 50 Health: 58 HP: 58/58 Intelligence: 11

Also has 864 EXP to spend.

OR....should I just start over with a different pet? I heard once level is up it gets longer and longer to train.

You can just autotrain speed, hand train level to be able to train your other stats (should be level 24 for health, level 25 for defense, and level 27 for strength). It is not a good idea to autotrain level as effective training requires you to have as much control over level as possible.

I'll try that, thanks!
