A giant troll is a crossbreed between a troll and a hill giant. They resemble oversized trolls with reddish brown skin and red-rimmed eyes. In battle, a giant troll may wield a large spiked club made from a tree trunk or a house timber, or grab a human-sized target and wield the struggling victim like a club, beating a new target with the body.
Giant trolls are found in tandem with both hill giants and trolls and sometimes both. In these groups, the hill giants are often the leaders with the giant trolls serving as elite muscle and the normal trolls serving as the scouts and "pets."
