Rragar's Menagerie

There's actually a bug on the second floor. In the dungeon you find a Boss Key, needed for the Boss Lock inside there. But if you want to proceed by clicking on the Boss Lock with the Boss Key, it asks you for a Dungeon Key.

The end bosses are: Hidesplitter, and Rragar, when defeated (both, start with rragar, as he has resuurection chant!) they spawn a Hidesplitter's chestit drops:
 * Hidesplitter's Daggers
 * Hidesplitter's Shield
