This is an existing quest on live that has a couple of interesting twists on Rolath:
Find Saemey Wirewhisker in cat town in Stonebrunt and say to he "open a portal". She will transport you into the first floor of Tower of Frozen Shadow. At this time only the first floor is available, no keys drop yet. Alternatively run to the waterfall at the North edge of Stonebrunt, proximity to it will port you inside Tower of Frozen Shadow approximately where you would port to the second floor. This allows characters whom are not liked by the Kejekans to gain access to the Tower. You can exit the tower back to cat town by clicking the portal which would have normally exited to Iceclad Ocean. Or if you want to be ported back to the waterfall, click the portal which would have normally ported you to the second floor.
Purifying drops from the Temple of Frozen Shadow can result in weapon augments:
There are also Crystallized Shadow armor drops that can be purified. After a closer review of the items on live, we have decided to remove the race & class restrictions that vary between items and allow all races and all classes except pure casters (Nec, Enc, Mag, Wiz) to use the purified armor augments (effective November 2021).
The same is true (above) for the weapon drops and their augs (November 2023).
Turning in Orbs and Dust can give you a new friend for awhile.
