Hey, im up to the part where you have to put the pebble on the gravestone... im doing it but it just says "it fits perfectly, but nothing happens" Why is this what else do i have to do. Thanks

I had that same problem too. It was because i was wearing something i couldn't wear in the temple. Check your clothing

You can't have any weapons, armor, or runes.

Thanks now im stuck again.... i gotr to the very very last bit i put all the runes on the pillars and necklace on the statue... but when i do that the room floods and i end up near the house... how am i meant to use the urn on the chalice? thanks...

INSTEAD of clicking take-treasure, just use the urn with the chalice.
