Very odd to me that they include dungeons with monsters we can't get yet. Master dragon dungeon was pretty easy...Will be trying legendary next with Ra/Horus.
Master was very easy with Horus/Isis team and double horus. Not sure I could do legendary with a Horus team right now. I would need a lot more levels into the supporting cast. Final boss has over 2 million HP.
Anyone beat Legendary yet? What type of team did you use?
