I have Tiranwwn, Morytania, and Kandarin unlocked for context
Received a Master clue after todays update and it requires me to wave at castle Drakan with a Dragon Sq shield. From my knowledge i unfortunately cannot get a shield right half outside of the legends guild to make a d sq.
I can also confirm that Falo is STILL BROKEN for me even after the Leagues IV - Post-Launch update says it's fixed. I have only Kandarin and Desert unlocked and no luck with my master clue.
