I finally managed to reach Diamond tier, then Diamond 2, then 1, and I’m very close of reaching “Mithril” tier.
How I did it? I was lucky enough to get a “Major Shield Rune” that gives 20% defense bonus for my troops, for seven days. And I also trained more Tier 3 troops.
So, I revisited all the locations from “Clearing the High Pass”, this time using all my Tier 3 troops (around 15k), “Scorpions” and “Elven Warriors” until 99.900k troops.
Hero level 203.
And I got around 22-27k score for all locations. I even got 40k score on a location from the first map from “Clearing the High Pass”.
If you have any tips, please leave in the comments.
