Purple And Blue

Please help, I'm lost in the point where i'm supposed to follow the hints to the cave.

 

What quest are you talking about?

 

Read the signs in the cellar carefully!
Please, I didn't make it THAT hard...

 

So i got pretty far (thats what i think), then at the parkour my frames just started freezing for 5 seconds, every 5 seconds, please tell me I'm getting close to it being over ;-;

 

im stuck at the msterious cave part

 

This quest is said hard for a reason. Its hard to do

 

Yeah, the signs say that there's a button in the tree that when you press it'll open up a secret cave/area. However I can't find a tree, and each sign has an X y or z highlighted. I have to check that out again...

In the bottom of the middle island are three buttons which when pressed open up a secret passageway (I figured that's what was meant to happen?) and then if I try to enter it refuses, and has some red writing (can't remember specifics)

 

...
False cave.
There is a cave close to the lake.
Find the button on the tree, enter, find the helmet...

 

I give you an hint: You gonna need a LOT of potions

 

Ye, the parkour is Bs

 

Figured it out after posting yeaterday

 

i cant get in the wizards basement....

 

After defeating the Gryndilin chief, i had to uncast the spell using Nedlom's instructions.
So I used the item which was dropped by chief on enchantment table in a building next to Nedlom.
It created purple particles, showing the way to a room upstairs.
The problem is that i don't know what to do next...
