FAQ

Which combat level formula is used?

`combat = ⌊ 0.25×(defence + hitpoints + ⌊prayer/2⌋) + max(melee, ranged, magic) ⌋`, where `melee = 0.325×(attack+strength)`, `ranged = 0.325×(⌊ranged/2⌋+ranged)` and `magic = 0.325×(⌊magic/2⌋+magic)`. The three branches take the maximum, not the sum, and the floor is applied once at the end.

Does prayer count toward the combat level?

Yes, but only half: base includes `⌊prayer/2⌋`. Prayer does not enter the melee, ranged or magic branches, and does not affect max hit. So raising prayer nudges the combat level up slightly without making your attacks hit harder.

Why is the max hit so low?

Because the equipment bonus is assumed to be 0 (empty hands, no bonus), so this is a floor. A real value needs your weapon strength / ranged / magic bonus in `⌊0.5 + effective level × (bonus+64)/640⌋`, with the effective level being the level plus 8. Magic additionally depends on the spell; this is the structural value with no bonus.
