Helped some randy named isweng from the cc skull hunt his "killer", we found a skulled 74 and dropped him but I accidentally tangled the wrong guy so I waited out my skull with this guy who attacked me at 8 minutes left. After 15 seconds he realised he wouldn't be able to win and stopped and said it was his brother. I gave him 2 rocktails for some stupid reason which gave him more reason to attack me again which he did. It was a close fight despite the combat difference because my stats are really spread out and I only had 80 range. After about a 3 minute fight he started to run but fought back at the end. I had no food but my only option was to keep DPSing him. I ran back but he followed so I kept trying to kill him. He ran once again and then turned around and specced a 17-0. This put him above my hp. After multiple 0s he dropped me but he was only <5 hp and the poison from my ddp+ dropped him. Shortly after arriving in Lumbridge I received 2 keys (mine and his). I ended up making ~900k but lost a fair bit of melee stats and hp.
TL;DR: Don't trust randoms in cc
My key was the 1m one this was his:
