How do you get 99 def in runescape?

There is no one definitive way to get 99 Defense in RuneScape, but there are a few methods that are generally considered the most effective. One way to achieve 99 Defense is to train primarily at the Barbarian Assault minigame. This method requires purchasing the appropriate rewards from Commander Connad so that you can participate in the game’s higher-level waves. Another popular method is to train at the Warriors’ Guild, which offers a wide variety of enemies with high Defence levels. A third option is to use bonus experience weekends and/or other boosts such as Dungeoneering lamps or Tears of Guthix to raise your Defence level more quickly. Whichever method you choose, be sure to focus on raising your Defence level as much as possible so that you can reach 99 as quickly and easily as possible.
