My worst mistake was assuming guthans would heal me when I was fighting kalphite guardians I lost -Guthans Warspear -Guthans Helm -Obby Cape -Obby Sheild But my worst lost was when me and my friend combined our money to buy a santa back when they were like 18M I gave him 9M cash and about 1M in items. The next day he gets on and says his brother was playing and he got scammed.
