I'm now on the Lodric-Level. I gathered the 2 gems opened the door and tried to kill him; impossible, as he's stuck at firing magic balls and raising his minions (where I get to use the swords power with 999dmg). Anywho, I guess I'm still missing something of the game, so I tried the door on the right side but this is like the secret on level 2(?) where I guess I need the bow.
So this is where I'm stuck.
I've found the "green stamina orb thing" (trap puzzle). I still have the aforementioned bow-secret to do. I still have to get to the left side of where you first encounter a Skeleton (on level 3)
Other then that: I've been "everywhere". What am I missing? Where do I find the bow?
