TzHaar-Ket-Zuh was the only banker in TzHaar City, prior to the graphical rework of the TzHaar. Players could right-click him and select "Bank" to access their bank, as well as access their Grand Exchange account. As with the Shilo Village bank, his bank did not have a booth.
He was found conveniently very close to the TzHaar Fight Cave, and therefore was often used by both Tzhaar Fight Pit and Tzhaar Fight Cave and was often used to resupply for the next round or attempt.
He was replaced by TzHaar-Hur-Zuh during the graphical rework of the TzHaar.
