I can confirm that this method works for both ranged and melee. I went from 87 combat to 95 combat in a few days due to Google Remote Desktop. I would highly recommend this guide for anyone like me in their 30s that doesn’t have time to dedicate fully to the grind. Next stop, 99 str.
Also thank you to @Simbalalala for teaching me this method and loaning me a blow pipe, anguish, scales, and ammo. Huge help for my first ever 80 on my account.
