I know that this question is asked many times by various people, but, what is an appropiate level for a wizard to enter Avalon at? I'm at level 73 and has not done any part of Wintertusk. I've just started Avalon. Is this just right, too high, or not enough? Any responses would be appreciated.
You're at a typical level. I would recommend doing Wintertusk though. By skipping the spell quest in Wintertusk you are missing out on your most powerful healing spell, Availing Hands at lvl 55, as well as Mana Burn lvl 72, Supernova lvl 75 and your lvl 75 minion Nerys.
The minimum recommended level for Avalon is 70. However boosting yourself up a few levels by doing Wintertusk first will get you new spells when you hit 75 which will help you quest through Avalon
