He is found in Bandos' Stronghold, which requires a Strength level of 70 and a hammer to access. To enter his quarters, players must have killed 40 of Bandos' followers throughout the dungeon, with goblins being the easiest of the followers to kill.
Like other God Wars Dungeon bosses, Graardor roams around a rectangular room with his bodyguards until a player enters, attacking them on sight. He attacks primarily with melee, and his bodyguards use a different combat style each. Graardor may also use a ranged attack where he slams the ground. If all players leave, his health and stats will be reset.
At Old School RuneScape's first birthday event, players could speak to General Graardor, resulting in the following dialogue:
Player: Erm.... hi?
Graardor: Puny 'uman ffffedddfded meeee
Player: Yeah right okay there's no point taking this further.
Graardor eats a nearby ankou.
At Old School RuneScape's fifth birthday event, a very large statue of General Graardor was present.
Prior to the 19 January 2017 update, Graardor had a Magic level of 280; this was reduced to 80 in order to prevent the Twisted bow from dealing massive damage on him, and to compensate for the decreased Magic level, his magic defence bonus was increased from +65 to +201. However, this ultimately resulted in Graardor being much easier to kill with magic attacks, and a hotfix was applied the following day in order to rebalance his magic resistance.
Although he is the last living Ourg, General Graardor does not drop Ourg bones.
