Magnus Exorcismus

Magnus Exorcismus build is one of the most fun character to do in this game. Killing lots of undead monsters in a single cast. You need dex for casting time and int for damage. Int should be prioritize more, because being an exorcist drains your mana, especially if you are wearing mistress sunglasses.

Fast Cast exorcist - Prioritizing dex more than anything else and having a fairly amount of int. Killing undead and demon monster in less time because of the decrease in casting time. Spamming turn undead is easier and you have enough vit to survive.If you don’t want to get Safety Wall because of blue gems hassle, this build is perfect for you. Just get the Kyrie Eleison or Assumptio instead. Or you could have the Safety Wall and undead monsters would be a no match to you. You also have to get Meditatio to compensate for the lack of int in this build. Gloria to increase your chance in safety wall. Beware, you might cast Magnus Exorcismus twice because of your moderate int but the good thing is, this build is flexible. You can use this in boss hunting parties, pvp and siege.
