That's right kids, its "the ultimate wizard in terms of attack and defense."
But really, this is Wizard of the Order that gained hunter, 2HP and while is an immediate threat, still dispenses a doom that may haunt you next mythos phase. It gaining Victory 1 also means he's not just going to get shuffled in all the time, something that Chapter 1's core loved doing.
Overall, combined with Zealot's Aloof and the Treachery, makes an encounter set that you cannot ignore and, takes extra actions / resources to deal with and giving more incentive for the party to stick together.. Comparatively, original cultists made you go to them as action economy, and prioritising Fighters (who had less movement tools to work with back then) to stick to more central locations or head off threats.
If the original cultist set was Arkham Horror the board game's fires that you must go around and put out in Arkham Town, these are the guys starting them.
(I'm mainly here to make the YGO joke, but I also wanted to give my 2 cents.)
