This is how he looks like:

Now we come to its attack details:
Once Thorax starts jumping it starts rotating its Blades and if it lands on a player it deals alot of physical damage.
If the player is able to avoid the Thorax it will still follow him , spinning arround trying to reach the player with its blades.
The blades are poisoned , so if a player gets hit by them he gets stunlocked and recieves poison damage.

What do you think about this suggestion?
