I had a one-way gate and a haunch of meat of spare in "Uh oh, no loot bags…" i mean, i saved it with silver just because i had two things that i didn't need, putting them wherever meant to pass it with gold.
I had two endings but in both cases I help Malior, I collected the whole gems but then I realised the escape at left side so I climbed it up and it was too late. I also used floated over the altar but same ending, I'm now going to kill the evil.
