The servant’s master has given her a tall order, to retrieve a tundra rose, which only grows in the harshest of cold places. You already know you’re heading to Jack Frost’s Playground, so travel there. Specifically, you want to fly to the coast just east of Coldera, where you should find a Tainted Monster. This is level 68 Ziggy, which is pretty much the same as Zagg. However, being level 68, this thing definitely hits hard, as even at level 70 or so, most hits from this creature will take off most, if not all, of your health. Your best bet is to try and stay away, using ranged attacks to whittle down its health, along with some poison weapons if you have any. You’ll receive Songbook No. 23 for defeating Ziggy, as well as the Tundra Rose after the battle. Return to the servant to hand over the rose and finish the quest.
