The Shard of Mirabilis

Today's #RPGaDay2016 prompt is: share one of your best Worst Luck stories.

After joining the gaming group I had stumbled upon in university, I rolled up my very first PC. He was a monk named Den, made using some options from Oriental Adventures and trying to use 3rd ed tripping rules effectively. Essentially Den could quickly move around the battlefield, tripping multiple enemies to give bonuses to the other PCs and occupying the big bad while still easily avoiding wizard AOEs with lovely monk reflexes.

Or at least, that's what he was intended to do. See, I have this transparent purple d20 that must be cursed. Whenever the roll mattered, I don't think it ever got above 13, and I swear it was weighted towards a critical fail. Den would often trip himself instead of the enemies, and most of his multiple attacks were wasted by rotten luck. This happened often enough that the DM and I came up with plot to explain it. Den's parents were killed when he was young (shut up he was my first PC) by shapeshifting beings who live on the other side of mirrors. His father's final attack before death shattered the mirror-man Mirabilis, who cursed Den and his father's whole family line. Breaking a mirror gives you bad luck; breaking a mirror-man is far worse. Den carried a shard of Mirabilis on a cord around his neck, which once per day let him re-reroll a d20--so long as it landed on 13 or under. The rest of the time, he just had to live with bad luck.
