Thanks. I have just discovered another larvae, the first one on the second row. I found the correct workshop (in the yellow area with the lifts) and picked up another ghost. I also found where to put the heart. So far no game breaking bugs and although I've looked at the descriptions for all the objects I've collected I'm still not sure if I'm looking for specific words or reading the clues and working out a new word.
Okay, nice to see your progression !
The clues are specific words written in the larvae language (which is our alphabet but mixed with oghamic design). You can find words written in the larvae language in the descriptions, and they correspond to some puzzles. There is much more objects than puzzle, so you have to find the good ones. On each door of the tombs, there is an object drawn ( à jar, a hammer, etc) which is related to the object that you have to find to have the good word.
I've returned 4 ghosts to the correct locations. I have two locked tombs, but I think they might both need the missing larvae I don't have. It's on the middle row on the right.
The two doors I have left are the one that looks like scissors and the one with the deer / stag head. I think the clues are the copper mirror and the relic, but I'm not 100%. I've been everywhere multiple times and talked to all the ghosts I can. I also found two doors with multiple larvae places, but no clue image.
I have one blue spinning circle on my staff and I can't see any of the others.
Did you go back to the manual : If you find objects or unlock part of the game, some clues have to appear, and especially the words for the locked doors. We work together with Playtiles to provide extra clues in the manual for this kind of situations.
I can't reboot the game from my location (christmas thing, you may know), but I think that you miss the U/V larvae. So you have to pass the trial of Llwyn, it's located in the red aera, close to the tomb where you find the armlet, behind the door with a fox head on its pediment. It's a 3 larvae puzzle, but the answers are engraved in dedicated rooms near the door's area (there is an animation on each room when you enter).
Thanks for all your help. 6 ghosts have been returned. I have opened all the doors in the hub except for the one at the very start and I've gained to ability to read all the text. I just need to work out how to unlock the start door. I've read 3 pieces of text on the wall but still not sure what to do.
