Hi, some pets grow marginally larger every 10 levels, and some don't. Is there anyway to know if they grow or don't grow? I really love my Balrog and cant wait to see it grow even larger in coming content updates. On the other hand I was a bit disappointed that my PvP colossus is... not a colossus... more like a cute-sus. Basically I would like to invest in pets that grow but I don't know which ones do/don't.
Also in regards to growth, I believe the cheerful Tinsel Owl stops growing at level 30, whilst the original mechanical owl continues to grow larger. I think it maybe a glitch.
