Gasbags is one of the best support tames in the game. It has great weight, is tanky, and when you level up speed, it can go very fast while flying. Not to mention but they are adorable. I suggest players get gasbags on both PVP and PVE. The only drawback is it does no damage and if you aren't careful you can kill it by falling to your death.
They can inflate and then they can do three things, do a huge jump that will deflate them, float/glide, and do a knockback attack that is similar to the diplodocus' only attack. They can also seat more than one person at a time
So bc most comments are from pve players here a pvp tip use them for soaking have them mate boosted veggie cakes yuty roar a deadon on passive healing and a good saddle no heavie or auto will stay in your way with a good gasbag and a food stat deadon
