Awakening of Evil

What specifically caused the difficulty? )

I'll write it down now.

It's just that if you don't use Furies at the beginning, almost all battles either result in significant losses or you have to avoid fighting altogether.))
For example, the dolmen and the chest were guarded by 2 packs of Ghost Horde units.
And the Temple had 2 Zealots and 2 packs of Horde Shamans (both the 1st and 2nd forms).
