The fight didn't last much longer than that after Tyal transformed. It didn't matter how much Gale had enchanted himself. He was simply far smaller than Tyal's beast form and too weak to oppose her domination over the wind. He still tried to fight back, but his tempest was quickly swallowed whole and destroyed in the violent tornadoes emerging from Tyal's typhoon.
The spectators had to take shelter beneath the secondary magic barrier of the arena to hide from both rain and hail. Arad lifted his hand and caught one of the hails, which was at least four meters wide. It was quite horrifying to see one as big as a room in his house.
Thankfully, the hail was mundane and not magical, which made it easier to block with barriers. It won't even harm Claug if she were to fly through it.
This meant that Tyal was at the level of a great natural disaster and nothing more than that, which was mainly due to her still not being used to it.
