I’ve been preparing to clear dungeon.
Today I found that most of the building and troops in
high-level dunegons became elite-boosted.
Those levels become not penetrable!
Sad, mummies lv4, which were near grasp, are gone.
I think that it would be better to leave original duneons untouched and
make another high-level dungeon, which has troops, monsters and buildings with
elite-boosted, for high-level players.
