I was about level 80 and had my first whip. (This is a few years back when they were 3m). I was doing slayer and got Killerwatts. I didn't have any prayer potions so I took my awesome blue dragonhide. Sure enough I was hit hard, and escaped on 1 health. In hindsight it wasn't as bad as I thought, since I wouldn't have lost my whip. It was bloody scary at the time though.
