Yep leave the sun wolf then the ram until last. Once ram is out along with everyone else, he surrenders. Beyond that, just keep swimming!

For the final battle, the underwater rune is a cheat. If the arena is covered with water, then just run along the bottom to the very end, float up and dash to find the right angle to get to the stairs.
If you pass the ram as the most unpredictable one at the beginning, and leave the solar wolf for the end, then you pass almost without damage.

There is a better option, a fast swimming rune, you just swim and the balls don't hit, I went through it the first time)

thats how i won after having lost alot

well easiest way to defeat wolves if you got the rune for walkin on does thorns get up a the hight ground what doesnt have thorns and stay there till the wolves use the one attack and strike at right moment

i just swam using the wolf dash when i beat it. lol

wish this could be a text guide aswell :/
