A Zerker Pure Build is an account build known to have the lowest defence level with all requirements to obtain Barrows gloves. Although the Barrows gloves don’t have a defence requirement, the minimum defence level a player can acquire is 35 when all quest requirements are completed, assuming the player does not accept Daero’s training at the end of Monkey Madness I.

Completing notable quests shown below will increase the defence to 43. Players can train freely to 45 defence, the maximum defence for a Zerker pure account. It’s best to complete quests that provide experience rewards first before training combat, to not obtain a higher than desirable combat level.
