Strategy

Most of Aul's attacks are, well, attacks with a capital A. High Evasion and Attack Block can greatly reduce the effectiveness of Aul's attacks. Additionally, they mostly deal cold and physical damage, with none at all of any other element or chaos damage (assuming that there are no mods).
