Guide to unlocks (Archers/Stages) - SPOILERS

Stages

You'll get it randomly when selecting stages ... Randomly (using the round random button) in versus mode.

Finish King's Court (boss) in any difficulty in quest mode to unlock

Play Versus (2-4) on Sacred Ground - It requires that you've played every single classic (non-unlockable) maps at least once before.

When you have unlocked the other 3 levels, go to Archives and to the last page. There will be a clue to solve. You must input 3 directions for each stage. You can get clues about those directions in the each stage in the background and decoration of the level.

Right - Up - Left --- Right - Right - Down --- Down - Up - Down

Trial Hidden Treasure

If you get in Towerforge 2 via Trial mod, you'll see a breakable block on the ground. Break it with bomb arrow and get past the secret wall. There will be a "clue" about where to get the 7 triangles. You will find them in 7 differents trial stages, well hidden. You don't have to actually beat the trials to collect them

Sacred Ground 2

Right above where you start there is a platform with a lit and one unlit brasero. Light the unlit one with a flaming arrow trough the lit on to spawn the chest.

Twilight Spire 2

Right above where your start, there is a platform. Go on it, and the chest will spawn (use dash to reach it)

Backfire 3

Go down the hill, climb the left wall and there will be a fake wall to get trough to reach the chest.

Thornwood 3

Get to the platform where the left most dummy is (above your head) and get past the left fake wall. Cross the bridge and get past another fake wall left to reach the chest.

King's Court 1

It's hidden under the blue block (fake floor). Rush it before it spawn, or just shoot and arrow to prevent it from spawning.

Sunken City 3

Go to the lowest part of the map (like a hole in the ground with 2 dummies), then get past the right fake wall.

Moonstone 3

Get the bombs arrow, then break one of the glasses (those glasses one you can't get past, but you can shoot arrow trough) by shooting a bomb arrow INSIDE the glass. The bomb has to stick to a wall while it's in the glass to break it. Then go o the previously "unreachable" area, the fake wall is in the ceilling you'll have to do a bit of climbing.

Go back to the Master and see what happens ... (Towerforge 2)
