Forest Giant

Forest giants can be found in deep and primordial woods. They range in height from 12 to 14 feet tall, and their skin tone goes from a rich earth tone to a tan. Their hair is wild, unkempt, and usually shot through with leaves, twigs, and other forest debris. They wear the skins of animals they have slain and eaten and fashion trunks of small trees into warclubs. Forest giants will also have a thick growth of gray-green moss covering most of their bodies and gear. They are proud of their moss covering and grooming it as it helps in their natural ability to camouflage themselves. Forest giants are not stupid and have average intelligence. They construct traps, blinds, and funnels for hunting game and ambushing those entering their territory. 

While not chaotic in nature, forest giants tend to be cruel and show no mercy to any creatures they come across. Creatures they capture are tortured for entertainment before eating them. Due to their voracious appetites, forest giants do not tend to stay long in any area and constantly roam between a handful of favored hunting grounds found throughout the forest where they live. They are omnivores but prefer fresh meat. 

Forest giants are solitary creatures but can be found in mated pairs. They rear their young for roughly one year before driving them off to find their way in life. Forest giants at this young age are as large as adult male humans and aggressively targeted by other predators within the forest to prevent them from growing into adults.

Combat
Too large to be effective hunters that stalk their prey, forest giants have become masters of ambush and can remain motionless for hours on end. When confronted with a foe they feel might be stronger than themselves, the forest giant will use their natural ability to blend into their surroundings to hide. ​

In combat, a forest giant uses their club and pushes over trees onto enemies to pin them down. This tactic is a favorite when confronted by a pack of animals or a group of adventurers. They usually prep several trees around their ambush site by loosening the soil around the tree's roots. If they feel the need to flee, they might topple over trees to bar the way of their pursuers.
