About training Strength

Strength xp comes from melee damage - 4 xp per point of damage on the aggressive combat style - so training is all about finding monsters that are pure hitpoints with no defence. Knock out Waterfall Quest first for an instant jump to level 30, camp crabs or Scurrius through the mid levels, then finish at Nightmare Zone with Dharok's or Varlamore's sulphur naguas. Every Strength level raises your max hit, which quietly speeds up every other combat grind you do.

Did you know: Maxing Strength from 1 to 99 takes 13,034,431 xp - roughly 54,300 sand crab kills at 240 xp apiece, or about 124 hours of lying at 1 HP in Dharok's armour inside the Nightmare Zone.
