I stopped playing for a while, two months ago I came back and so I do not have several dragons, I have 2 days trapped in Sentinel level 13, any suggestion of how to defeat Champion type?
Another vote for red/white/blue combo (Galleon level 12) against Mithril!
kudos to everyone ... I had given up entering tournaments because I couldn't get past the 10th round. Since visiting these tournament threads I've finished 3 of the last 4. The last tournament was just too long for me.
I'm not sure whether they want more people to finish but I'm now entering tournaments and leveling up dragons for battles.
Jus spent 50 gold speeding up battles and in the end ultimating Mithril because my Toothy dragon can't fight... what a waste
Red-white-blue combo didn't work for me unfortunately, both Galleon lv15 and Fungi lv14 went down to Mithril.
For those still struggling with Mithril. He just fell to Diamond 15 on the 2nd try. Lost to Fungi 14 twice passion 15 Metal 15 and several Baby fires.
Just had a weird glitch:
Last battle, I fought with Rainbow Sentinel, I won without hustle, then my game resets, but the arena has a 1 hour timer, and my Rainbow Sentinel isn't exhausted, the Tournament isn't finished, and the prize-dragon isn't in my inventory.
Weird.
