Im just curious what HSD I need to train a pet up to so I am able to trade for uc-draik-royal-plush?

I know it takes a long time to trade so, how many years would it take to train to that estimated hsd?

Also, is it worth it to train agility at least a little or not bother?

I really don't do anything else on neo so I figured since time is passing by anyway, why not train a pet.

thanks!
