Finally managed to afford a
Saradomin Godsword.
It dwarfs the other Godswords in terms of usability because of its Special Attack which heals half the amount of damage you do or otherwise would have done if it kills whatever you're fighting. With no cooldown on Special Attacks, it makes it pretty damn popular. Certainly a feature I could've done with years ago but couldn't get the bloody thing because it was so expensive due to high demand.
