Before you start reading / using this solution you have to know this is more a preparation guide with tipps. There are no tricks or short cuts to skip parts of the level.
Indeed imo. is the run with Zoya much easier than with Amadeus or Pontius, because you have the bow and the hook. There shoud no real barriers or problems stop you.
This doesn't work in coop!
It can be helpful and recommendable to do this in your second playthrough after you collect all / as much as possible items from the chests / crates; collect all the / as much as possible green exp. bottles and use level select.
- Gem of Resurrection (found in Chapter 13 "Bramblestoke Village")
revives from death one time
- Health Vial (inventory) (found in Chapter 10 "Shadowthorn Thicket")
restore autom. 25 % health
- Blue Masterstone (found in Chapter 8 "Throne of the Lost King")
Increases number arrows by 1.
- Prism of Light (found in Chapter 10 "Shadowthorn Thicket")
25% more health and energy from checkpoints
You can also use others (which increase Health / Mana or damage protect) but this are the ones which make the most sense imo.
- Chapter 2 ( Academy Hallways) - Easy
In the beginning you automatically start as the magician (Amadeus). Just switch to Zoya, this first switch in the beginning won't affect the achievement.
If the "game helps" (the big game pad) not disappear from your screen just hit the back button to switch in and out your inventory.
In the very beginning you have to open a stone blocked passage with a stone fist. Just use your arrows to push the fist forward and into the wall.
After the part with the "shooting fireballs" you have to cross a wooden britch (destroyed by a falling rock after you reach the other side) to activate a switch on the ground (which will open the iron gate in the ground between the fireballs). To get back here shoot with an explosive arrow the wooden planks over the chepoint / blue orb. Now you can use your hook on the hanging stone to get back.
After you jumped over the big wooden water wheel (without water) use again an explosive arrow in the upper right edge to destroy the wooden planks and "free" the weight to open your way.
If you think that there are other parts in the chapter which are complicated and should also be explained by me please let me know.
