Your performance and skills in bear form can be improved with a lot of talents
As a bear, you will be able to take a lot more Habbo credits damage than in caster form, and you will be able to perform tasks like tanking or staying alive in PvP, like a warrior would (although never quite as good).
With a talent point in Feral Charge, you will also be able to charge like a warrior, which is great for pulling. You will also be able to charge mid-fight, which is great for stopping runners.
Your performance and skills in bear form can be improved with a lot of talents, mostly in the Feral tree.
Aquatic Form: You will receive aquatic form at level 16. It will make you look like a sea lion, and you can only use it while in water (because a sea lion out of water would just look plain silly).
Oh yeah, it will also double your swimming speed, so you will be able to swim as fast as you walk, and you will get infinite breath.
Shifting to aquatic form costs 5% of your base mana without talents, this can be valuable to save time crossing large distances under water, but also to escape your enemies.
Escaping in aquatic form is always an option when near water in open field PvP, although hunters pets will still be faster than you.
