Today's daily: Fight a Painted Greyhorn in Zamunda Outskirts.
A friend and I have looked everywhere for one. We ran all over the place and even went into Zamunda. No Painted Greyhorns. We went into all of the sigils. No Painted Greyhorns. We switched to all of the realms. No Painted Greyhorns.
If there is one that spawns among the Greyhorn Mercenaries, then it is more elusive than the Elf Pathfinder in Firecat Alley.
Fighting Greyhorn Mercenaries would make more sense for a daily.
I have good news and I have bad news. The good news is that the recent Test Realm removes this as a possible quest objective: https://www.wizard101.com/game/update-notes/testrealm -- The bad news is that there is a still a chance this will happen again until we update the Test Realm to live. Sorry for the inconvenience.
