What level of each is required? It's unspecificied on the achievement page

it used to be you needed to get the 1000 in STR DEF HP and SPD (maybe LVL too?) because those were the other achievements that you needed to get Super Pet, and those were the maximum tiers at the time. Now that the maximum tiers are higher it might be different. I already have this one, so I can't test it.

I'm not sure honestly maybe a battler like or can answer?

Super Pet - Have the following pet-related achievements: Strong Pet, Strong Defender, Speedy, Lots of Health, High Level.

I don't have the achievement yet so not sure. I think it is 1000 of each for those other achievements. I have over 1k in everything except for level but that won't be happening for a while. Though with the new achievement system being worked on and tested the Requirements should show up at some point on the new one.

thanks guys!

you are welcome. I do remember it was a long slog to get it so hang in there.

I believe I got mine around 500 of each stat

I just got that achievement in the past few weeks. It is definitely 1000. I had all the others ages ago, but of course my level lagged and my battle pet is now at Level: 1015.
