Drakeroot is a special root that is used in the ranks of the Black Guard berserkers in Vanna. The root grows in the oases of the Tronin Desert in Southern Libaterra and gives its eaters temporarily more strength albeit at the cost of turning them into raging lunatics in the process. This has been very useful in battles, though, since the berserkers of Vanna have managed to keep their opponents in line with their ferocity and strength.
Some say that Drakeroot is just a variant of the Remonian Bud. However, the key difference is that while Bud causes hallucinations and makes people feel happy, Drakeroot causes hallucinations and makes people feel really angry.
