[color:"orange"]Act 2[/color] (game version 1.47)
lich cave statues (33 KB) - this file contains two sets of inventory files; the 'small statues' folder contains the 3 statues you need to place on the pentagrams in the lich cave, and the 'sapphire key' folder contains the key you should get once that is done.
The pentagrams can be difficult to see, but you can increase the gamma setting in the graphics options (crank it all the way up temporarily, if your monitor is too dark).
The statues should be movable until placed on a pentagram, so if you drop one (in that south east section of the cave) and can not move it again, you've probably hit a pentagram (assuming it is not stuck in a wall, or something). The 4 outer pentagrams form a rectangle, with one statue already placed in the top right corner (the key appears in a pentagram in the middle of the rectangle).
