I am so confused I thought Edea Florence was considered the strongest WH followed by Vihyungrang. Aria even confirms this while fighting Edea saying that when Edea fought at full strength that her pressure equal to that of Verate. And Verate is somebody on the level of the 4 great witches... Yet here Tasha says that Tania is just a powerful as Varete which would make her more powerful than Vihyungrang who is acknowledge as the second strongest :S Which in theory should make him even stronger than the 4 great witches if Tania is as powerful as Varete... So either the author messed up pretty greatly or Tania got a off-screen boost in her power without proper explanation.
