Divinity: Original Sin - Enhanced Edition

This achievement is unmissable and part of the main story.

It is apparently possible to skip almost this entire part, as I describe in the spoiler below.



The difficulty ramps up a lot in the end game and it has the potential to be enormously frustrating. I'm going to include a number of links to the resources I used to figure out how to get through it along with some commentary that I hope is helpful.

Once you enter the Source Temple you'll quickly learn the shortcut you were promised isn't going to work out for you. There will be no combat for this entire section, but there are a number of situations where having high perception (I buffed mine to 14 to be safe, but from what I understand, 9 will be enough-if anyone can confirm, that would be great). You will potentially be hit by poison and fire damage unexpectedly, so this would be a good time to swap to gear with perception, health, +Con and fire/poison resists.

The puzzle will also require you to navigate through areas blocked off by bars or grates. This can be achieved by throwing a teleportation pyramid through (aided by telekinesis), but a scoundrel with Cloak and Dagger or an Aerothurge with Teleport will make it a lot easier.

You'll also need to have located a total of 12 star and blood stones (our of 17 in the game). I kept all the inert stones over the course of the game as well as blood stones and had 9 inert stones (activated star and used blood stones) and 3 unused bloodstones. You shouldn't need to have the inert stones, they're just a count of how many areas you've unlocked in the Homestead. If you haven't unlocked all of them (the Temple is the last), you can use unused bloodstones to activate more rooms. If you still don't have enough, below is a list of locations put together by the Wikia that shows where you can find them. There is supposedly one in the entrance area, but I wasn't able to find it, even with high perception.

If you're unsure, continue through the temple entrance to the path that will be revealed on your map but is blocked off by rocks. Find a switch near the rocks to remove them and continue on. You'll come to a door that will either confirm that your memories are complete (you've unlocked enough of the Homestead) or that you're not yet whole and need to find/use more stones.

The actual puzzles that form the Trial of Ascension are quite difficult. You get some guidance from the developers in the form of a few books found in the library at the far end of the level, but they're pretty obscure. I'll put hints to the three most frustrating parts in spoilers below, but for a complete walkthrough, Youtube user Watchwithwaddy (https://www.youtube.com/channel/UCHEokFJkMX8eB8XIS8CQl-Q) did a great job going through the whole thing. I've linked his video below.

This really isn't too bad and the solution is explained in the books found in the library, but details are in the spoiler below.
