The large ogre would be as tall as a giantman, if it would only stand up straight. Heavily muscled, its long arms hang nearly to the ground, ending in massive hands that easily crush anything unlucky enough to be in their grasp. The large ogre squints as if barely able to see through its long, matted hair or extremely puzzled by the world around it. When standing downwind of this creature, it is evident that a bath is long overdue.
The large ogres in the Cairnfang Forest are the easiest to hunt for most professions because they wear no armor. They will also commonly drop either their flails or two-handed swords to attempt to claw you or punch you with a closed fist, which is a much less damaging attack. Polearm users will want to pick up a naginata to use against them if they don't use one already since their lack of armor makes most other pole arms hard to hit with.
The large ogres located in the Foggy Valley can be quite easy for pole-arm and two-handed weapon users. They wear double chain armor, which both of those types of weapons hit quite hard against. Although, be forewarned, the greater spiders, darkwoodes, and forest ogres that wander the area too can be quite a danger or nuisance.
Bringing a disk out to the Foggy Valley to hunt the ogres and filling it with their double chain can be good additional profit when sold to the pawnshop in Solhaven.
