A Zerker, short for Berserker, is a type of combat pure in OSRS.
These account builds are characterized by their level 45 defence and high strength and attack levels, and are named “Berserkers” because they get right to level 45 defence to wear the Berserker Helmet.
These accounts must be trained in a very specific way, and most of their defence experience must be obtained through questing as a way to obtain the barrows gloves. And those are really a must-have on any zerker.
In fact, if you do all of the quests correctly for the barrows gloves, you’ll be at exactly level 44 defence!
How To Use a Zerker
The best way to make sure your zerker is effective in PvP is to have a high strength level of at least 90, and ensure your attack level is between levels 70 – 99.
This allows you to wield some of the best in slot weapons, like the Abyssal Whip and Armadyl Godsword.
And this’ll ensure that your zerker hits pretty darn high.
Another important skill to have is at least level 94 magic, so you can cast the Vengeance spell.
This can rebound 75% of your opponent’s damage back to them, dealing massive damage (which is just what we’re after here).
It’s also crucial to try and time your Vengeances correctly, so that you hit for the maximum possible damage.
This can be best done by trying to cast it right as your opponent uses a special attack with their knock out weapon, like an Armadyl Godsword.
