I've got 4 evil elements & the masque. The last is in D'Soto's tower - where is this tower? Outside the main dungeon? There is a big building in the courtyard with 2 locked doors, but I don't see any way to get in.

Any help appreciated!

Look for stairs going up on the main level. Once you find these, ascend, the rest is easy.

You need to go into the castle.... to the plase where you got the Dildo like element from the horney vampire..... go to the room above, and there should b a lever. pull the lever to get outside.... and up to D'soto
