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.

How this Strength estimate is built

12,296,804 XP separates level 70 from Strength 99, out of 13,034,431 total. 105,000 XP/hr on NMZ Dharok's turns that gap into 117 hrs; 0 XP per dream turns it into 0 actions. No per-action XP for NMZ Dharok's, so the action tile stays blank and the hours carry the estimate. Gemstone crab, Slayer tasks, NMZ Dharok's report no countable unit, and features in hours only for that reason. 82 nights at 1.4 hrs a day covers 117 hrs of Strength. 127 hrs from level 1, if you switch at 10/40/50/60/70.

Decision example

12,296,804 XP: NMZ Dharok's converts it in 117 hrs, Sulphur naguas in 123 hrs - 5% more clock. Sulphur naguas returns 27.1M gp while NMZ Dharok's breaks even. Low attention instead: Gemstone crab at 40,000 XP/hr.

Limits of the number

105,000 XP/hr is NMZ Dharok's over a session, 141,750 on a perfect tick. NMZ Dharok's has no supply or drop value attached at all. Prices are 16 October 2026 estimates: 0 GP/XP today, and the Strength cost moves with supply.

Strength, level 70 to 99

12,296,804 XP - 94% of a whole 99 - explained twice. The 12,296,804 XP is identical in both rows, which leaves the Strength rate to explain the 5.9 hrs.

Method	Rate	Actions	Active hours	GP/XP estimate
NMZ Dharok's	105,000 XP/hr	no action unit	117 hrs	not estimated
Sulphur naguas	100,000 XP/hr	30,743	123 hrs	+27.1M gp

NMZ Dharok's saves 5.9 hrs over Sulphur naguas, which is 5% of the slower total.

A practical Strength route

Below, the Strength route from 1-40 to 70+: 3 switches, each tied to an unlock.

1-40

Build the base
Use quest rewards selectively, then train on low-defence monsters with the Strength style to grow max hit quickly.
40-70

Choose controlled or dedicated XP
Dedicated Strength is fastest for the skill; controlled training is sensible when Attack and Defence are still behind.
70+

Spend the damage breakpoints
Compare the next max-hit or weapon unlock with the time saved by a higher Strength level before planning all the way to 99.

Strength by goal

What changes the choice

Fastest: Use the highest-damage monster method you can sustain; Strength XP follows damage, so max-hit upgrades matter more than raw weapon price.
Shared combat: Controlled style keeps Attack and Defence moving but sacrifices the focused Strength rate.
Low cost: Slower melee targets reduce food and potion burn; the calculator's GP/XP does not include the value of your time.

Requirements and caveats

Your max hit, prayer, potion uptime and monster defence determine the real damage rate behind the XP estimate.
Combat XP is affected by attack style; select the row that matches the style you will actually use.

Common mistakes to avoid

Choosing a high-level monster with impressive theoretical XP/hr but insufficient accuracy or survivability.
Ignoring a one-level max-hit breakpoint that can change the entire hourly estimate.
