Snow Ettin warriors usually travel in pairs or as part of a group with Stone Summit and Ice Golem mobs. They can be rather dangerous in groups,though lone individuals can be dealt with swiftly. Unlike Gypsie Ettin of Kryta, they don't use Healing Signet, so they are more easily defeated than their cousins.
In Hard Mode, don't count on being able to knock these monsters over, as they are almost constantly in Balanced Stance. This can be played to your favor if you farm them with Shield of Judgment.
