Upon release, Zul-andra teleports were dropped in quantities of 50 per drop, shortly reduced to 20. This caused an oversupply of teleport scrolls, and was silently reduced to one scroll per drop on 15 October 2015, limiting the quantity of scrolls that enter the game economy. As a result the teleport scroll rapidly increased in price. This caused some controversies among the Oldschool RuneScape community, as players, who hoarded teleport scrolls prior to the update, were able to profit greatly due to the higher prices. On the day of the update, 9,092,122 scrolls were traded on the Grand Exchange.
Shortly after the 25 May 2017 update that decreased the average value of loots from Zulrah by 30%, on 15 June 2017 the drop quantity was increased from 1 to 4.
