Hey people,
in KR are some specials or "hidden objects". I will explain some of it:
Twin River Pass:
In the river are some fish jumping, try to click on one, and you got an achievement!
Silverroak outpost:
Repair the training hall for 100 and then buy up to 4 sylvan elf warriors (100 each).
Icewind pass:
Let's rain lava on the mysterious cave, it gets melted and buy the sasquatch for 500.
Stormcloud temple:
Hire the sunray sorcerer for 100. Hire up to 4 sorcerers, choose your target, and kill it.
I can't remember more, but if you know, post it here, please.
