OSRS Top Barrows Guide, Setup/Gear 

Austin Harlow Each brother has his own unique defense towards magic, I.E. Karil and Ahrim have higher magic defense than the rest of the brothers. Even still, if all brothers have zero magic defense you would need greater than zero magic attack for maximum accuracy. I.E. 0 magic defense > -15 magic attack, which nets the brother +15 magic defense. Having adequate magic attack is absolutely important to prevent splashing too frequently on a brother. The gear options I've explained in the video give the best combination of magic attack and melee defense.

i hope youre still around, most barrows brothers have -200 magic defense, how can you even make a video without knowing any info. having -30 magic attack changes accuracy by a fraction of a percentage

@@wowepicheroic I'm not sure where you found the -200 magic defense data. The wiki says the following for magic defense; Torag/Verac = 0, Dharok/Guthan = -11, Ahrim = +73, Karil = +106. Thus, for using magic on the four melee brothers it is optimal to have greater than 0 magic attack.
