I'm also stuck. I tried a lightning bolt, the lightning wand and a lightning bomb at prove your air mastery without effect.

Then in the dungeon there is a brass key I can't get In the wanderer heights there is a statue blocking the way and waiting for an item but I have no idea what to put there. I probably missed a hint. There is also a pedestal beside a closed gate with a sign "copseville". What do I need to put there? Tried a skull as I thought it maybe should read corpseville. Or it could be that I'm just missing an invitation letter for it.

I explored the western plantation: TThere is one donation chest where I tried to In the aged ambient woods I'm missing two orbs for the temple I think. I have the elemental stuff.

There is one puzzle where you have to put certain items into alcoves in the crypt of eternal slumber. I spoil what I tried Also in the crypt there is a force field blocking my way where I got the elemental symbols and I have no idea how to remove it.

There was other stuff but this is what I can remember right now. Thanks for a hint or two

Marten.

The issues you raised have now been fixed.

As it is open-world, there are two things I noticed when playing the mod:
1. The player is searching for keys wandering the various levels; or
2. The player has several keys and is looking for locks to use them.
You need to search the world as it is not linear. Swim, climb high, and look closely at the vegetation, especially in Wanderer Heights.
Keep an eye OFF the prize as the weapons, armour, and other bonuses sometimes disguise what you should be doing, or where you should be going.
I don't mean waste your time analyse every tree or area, but search generally.
I'm sorry that you're finding it frustrating.
I do not like mods that make the player stuck, which is why I changed both my mods to prevent this.

Read the previous reply for the item required to enter the Meditation Chamber.
Alright, no more clues for a bit

Thanks for all these hints. In conclusion what really got me stuck was that I didn't know how to get to

thx for the hints from me too !
finally I got the cursed skull and the brass key, that puzzle was really bad
not sure if that really helps me but I ll see
edit : still got that ornate key and no lock where it seems to fit in ...
edit 2 : still caught in wandering heights, where is that green gem ? and how am I supposed to disable the forcefield around the lever in the norteast, still carrying around that big bomb but it does not seem to do what it s description says

You're welcome, Banaora.

If you do not understand words or phrases, then I suggest looking them up.
There are other hints that are in languages other than English, designed benefit bi-lingual/multi-lingual players.

The hints are rarely cryptic. Players must spend time searching Wander Heights.
Look in the river, dig holes, kill enemies, pull switches, push buttons, look at buildings etc.

Marten,

finally I got the cursed skull and the brass key, that puzzle was really bad.

Why was the puzzle bad? I can't make puzzles any easier, because the mod wouldn't be a challenge.
My clues and puzzles are relatively simple in comparison to the main campaign or other mods.

thx very much !!!
that did the job, I was just stupid enough not to see that underwater section
that really helped me
mortar/pestle and rope can also be grabbed through the grate

I think I need a hint how to enter Fali, the safe haven. There are bars blocking my way and I'm guessing the last essence I need could be there. I have explored the forgotten sepulchre but have not found a way to open the gate to the teleporter. Maybe someone could tell me where to go looking to get access to the haven.

Read the note found in the treasure chest in Fali Safe Haven.

I must say, this map is very well done. Play it~ I'm loving it.
