Hey, does anyone know how much endurance and strength it takes to be able to join Grushk under the waterfall?
What did you do to get the green gems for the nightmare creature?
If you talked to Roushk/Othra, then you should “Give back” the one remaining green gem that was not taken by the nightmare creature.
I didn’t take the other route (where you steal the gems), so I don’t know yet how it impacts this part.
