Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks How to Open Chest of the Source (Souce) King?

as subject, where is the key to open it?

I found the key ,it's in the hall of death...
the founding is fortunately..and a bit of troublesome
in a hidden place and your perception will reach at least 14,you must first think how to do to your perception

I used a scroll of magical unlock on one of the chests, i think that's the one you are talking about.

no no no ..the unlock scroll is near the lab the hidden place is in the west where there is steam cloud,in the end of the steam cloud there's the place you must have at least 14 perception, the door will disappear ,and you enter dig the tomb,the key is in the corpse of Cassandra

As I am backtracing some of the secrets I haven't found, I also have not opened the chest yet.
What laboratory do you mean? What "hall of death"?

Greets!

to enter the hall of death you may go to a place in phantom forest,where there has four invulnerable sentinels.
there'a a bar you can pull it,and will send dead ones to the hall of death.
so you shall kill one of your partner and send him to the hall,then give a teleport pyramid and teleport to him

Thank you very much!

I'm not described well...you can seek yourself...be sure you have more than 12 perception(the other 2 can drink potion)

i am still confused. where is this scroll of magical unlock? near lab in hidden place in the west? where is it exactly?

The scrolls are random drops from monsters and they have randomized locations, but there are a few scrolls which have a fixed location.
One is to be found at Hunter's Edge in the secret cellar where you gain access the the wizard's house.
The other can be found in the Temple Of Death, if your Perception is high enough.

Both are in the 3rd story area, the "Phantom Forest".

I hope that helps without spoilering too much.

Edit: some people found a scroll much earlier in the game, I don't know if I just missed it or it was rng.

You dont need to kill anyone to get down there

Just place a pyramid on the teleporter and send it down then teleport the group to it.

There is an Unlock Scroll in Ahru Lab

Note that the loot in that chest is only ~ lvl 10, so if you wait till you have the key for it, the content will be relatively useless.
If you don't have enough Magic Unlock scrolls, just craft them: Magic Inkpot and Quill + Blank Witchcraft Scroll (Crafting 2)

You **could** kill a companion but why do that instead of just placing a pyramid in one of the animal corpses already conveniently placed on the portal for you? Those were placed there precisely so you wouldn't have to kill somebody to get in so why not do that? Also at least three of those sentinels can be terminated via hidden switches.

Actually there are three chests in your armory at the end of time that as far as I can tell can only be opened with magic unlock scrolls so I really wouldn't waste that scroll on the source king's chest....just saying. Unless I'm mistaken and there are keys for the chests in the armory I'm not aware of.
