100 GS achievement for beating the game and all secondary quests
~Complete the Prologue and all Secondary Quests~
*make sure you complete every quest before building the arc after the Treant Boss or else you will void the achievement and have to restart* Verified by commenters below
You can get the full completion in the prologue which is free. More achievements will be added in the future via paid DLC. There is 3 areas in this game, each having main and secondary quests.
All quests can be found on the map except for the chests needed to be found in the second and third area for secondary quests.
You can see their locations in my video below.
Area 2 chests @ 10:20
Area 3 chests @ 15:40
I go over how to kill the dark knights @ 9:10
This is my achievement walkthrough which is a run through of the game and achievements.
I show and tell you how to do everything needed for the full 1000 completion
