Top, middle and bottom of a fractured rune are found on Evil Eye in RunnyEye and are used for the Crafted Pauldron's quest. Bring the three parts of the rune and a fire emerale to Shakrn Meadowgreen in South Karana.
Crafted armor is the Old World quest armor for warriors. It used to be THE Armor to get past level 30, for the stats and for the look.
Nowadays it costs much less to just buy the armor parts than to do these quests. The stats aren't that good anymore and with LoY, you can dye your armor.
Of course, there may still be quest lovers (like myself) but then, I'd rather recommend doing the Twilight Sea quest. They are also for level 30ish, less expensive and the stats are a bit better.
