What are you guys talking about?
On Android it says "any" not "every."
But yes, if you use multiple Maxed toons it should count as multiple runs per run.
Yesterday I did all the Gangland achievements. What should have been 500 runs total, was actually 250 because I used 2 gangland Eds, at least for half of it.
My current Raven's Alter grind team is:
100% Wins... full health.
Best time: 0:49
Avg. 1:05
>Soccer Ed- Inspiration/Sacred/Green/Cosmic w/special
>Wickerman lvl. 7- Ragnarok/Cosmic
>Wicker Wolf Evolved lvl. 8- Vipers/Cosmic
>Wicker Owl Evolved lvl. 8- Alchemy/Cosmic
I used W. Ghost and had nearly identical average times, but the fastest was w/ the above team.
Also, no crashing on Android.
I imagine the Grimoir frags will be rewarded in other challenges later this month, cuz grinding this dungeon for frags is NOT cheap on ironite.
