Sacred Haven of Debauchery

It's difficult for a Warrior to properly develop this skill, as they have very few Spirit runes, and magic is also needed. It's not much better for a Mage.

Trading-3 only requires 6 Spirit runes. Considering training-1 (6, I think) and scouting-1 (1 rune), it's only 13 runes in total. 5 levels and "trophies on the road" are more than enough if you don't invest in anything that consumes a lot of Spirit. And there's no need to invest in anything that consumes a lot of Spirit, because after trading, you sell a diamond for 50k and buy maps, after which you can collect a lot of runes for everything you want and return to "restore order."

But not on "impossible" difficulty. Everything that brings additional income is a must-have there.

If "impossible" difficulty were truly impossible, you would think twice before investing in trophies or, for example, investing in reserves...

Why did you lie?

That's just how it seemed to me.
