Khadga is Medivh's apprentice, and antonidas is the exorcist of Dalaran's former leader. Medivh inherited the power of his mother, Al Govern, and Sargeras took control of his body.
In the first sentence, the rational discussion ended in meaningless strength comparison, especially the statement that "xx is stronger than xx", just like primary school students clamoring that Galen is stronger than Zhao Xin.
In the second sentence, except dragons, ogres, centaurs and Faye, others are crispy, including humanoid dragons, so whoever stabbed Faye with a knife does not mean that he is "better" than Faye.
Medivh's magic is incredible. Both Medivh and Egovin have the power of Kirin to hold the guardian, while the extreme of human demon king has far more magical knowledge than most demon kings (the so-called profession has specialization). However, only Egovin tried to single out Sargeras, who was in a weak state, and it was quite laborious, and he was also used by General Manager Sa without knowing it. This part of the content is seen by Medivh from hallucinations and described in the novel.
Personally, Khadga, the shaman who shines brilliantly in the 6.0 expansion, is greatly exaggerated. Before becoming Medivh's apprentice, Khadga was only a common law master of Kentory, because he was ordinary enough to achieve Kentory's purpose of sneaking into Karazan. Although he was exposed instantly by Medivh, he learned a lot in Karazan (including how to control a Griffin and how to calm the anger of a guardian).
The great mage antonidas is not an idle generation. He is much taller than Khadga. Khadga used to be Karazan's otaku. He was recognized by Kirin Tuo when he was young (in his teens). Within a few months of the invasion of the undead by natural disasters, he developed a magical enchantment specifically to deal with natural disasters. His knowledge is unparalleled and his personality has no dead ends. He is willing to be killed to cover the retreat of civilians (do you really think that the exorcist of Kirin Towery can't beat the fledgling death knight? )
Dick has been specializing in necromancy, and if he claims to be second in this respect, only Nero's regiment in the ice can be called first.
Ronin's level is still very high. He can control the airship with arcane bombs while casting spells, and at the same time make portals to push Jenna in. He is really the best among human wizards. Jenna took on a team of Cucalon, but almost everyone could do it. She has used long-distance transmission several times in a row and is quite accomplished in this respect. She was the best apprentice in antonidas, but she was shot after being with Blue Dragon.
In the plot, no matter who is unprepared, it is a one-shot thing (Dick is always a highly accomplished lich, he has a soul box. As long as the soul box is still there, it can be revived by powerful magic. If he is unguarded, he will be worth an entire army or even more, which is the usual performance of a mage in battle.
