Sorry to ask, but what's a max stat pet? I read about them everywhere but I don't know what they are??

A max stat is a pet that, as it's name indicate, have all his base stats maxed out. Usualy the mana isn't comptabilised due to the fact that boosting it is a fairly new mechanic.

If you are more visual here is an exemple.

I don't have max stats level 0 anymore but as you can see in the parentesis, he have 2000 health and 100 in evry stats with is as high as they can get. In aditions to this, some peoples are making superstats from the stat boost that the lost grove stats give them.

Thanks so much. I feel more educated now. Lol

Max stat:
2000 HP
100 Str/Int/Dex/Agi

Mana used to be considered Max at 100 or 120 (potentially 150 for venes), as Mana was reliant solely on the parents, with no possible way to raise it (high-rarity grove pets have made 150 possible in species obtainable in the Grove, and only the incredibly rare Legendary(/mythical) Grove Themed pets have 200 base- and passing on that Mana is difficult (since all stats pass on a random number from between the parents' stats.))
However, the ability to raise mana via Philters has been newly implemented, to a Max of 200.

So a Completed Max stat would look like
2000
200
100
100
100
100
(I doubt there will be much of any of those for a while, with how recently the philters were added- it'll take time for people to breed for the requisite amount of generations to get the Mana up that high)

(there are also Super Stat pets being those who have almost max stats, being taken over 100 by Grove stats (eg. a pet with Str 90 with a +24 grove bonus has 114)). Maybe some of their stats are max, but not all)
Super Max pets being those that do have Max stats in all stats (and 100+ mana) along with grove bonus stats, making them 100+__)

Thank you
