An attack's primary benefit is being able to OSRS gold use top-of-the-line weapons, such as godswords or chaotic mauls and the Noxious scythe, and using these weapons can deliver high-quality and precise damage to opponents who wear armour. In EOC they can use the abilities Barge and Slaughter which are important for attacking targets who are trying to escape, or the Special Attacks of the AGS or Claws for legacy.

A strength purist has one weapon to choose from and that weapon is the lv60 Tzharr-ket Om, however they can do a lot more damage per combat level with normal attacks when compared with all other types of pures. Although they may face accuracy problems against opponents wearing armor, they do deal more damage than attack purifies against opponents who have defence levels that are lower than lv1.

Reaching lv60 strength takes less time than 75/80/90 attack which means you can begin making PKs faster. Mauls are very cheap to replace in case you lose it upon the death of. Strength pures are able to access the strong Berserk ability, however, they'll need to purchase a few attack levels for the ability to utilize certain of the most useful Attack abilities in eoc, and also do not have a unique attacking ability in Legacy.

Defense levels could be completely left out in the old game, but in eoc the ability to be free is essential. Always ensure that your mage or range is 50% or less of sum of your attack+strength.

Leaf does make a good point, and if dual Ascensions are better than Nox and cost about the same cost, then there's no reason not to cheap OSRS GP get the dual Ascensions instead.
