Duplicate items glitch:
Get two or more of
the same magic scrolls and press X on them twice. Go to whichever item
you want to duplicate and drop it. You must have one of the items on
you for it to work.
Evidence chest location:
In Shivering Isles, south
of Madgod's Beet, is a cave called Corpserot passage. At the very
beginning of the cave is the Evidence Chest in both Mania and Dementia.
Free deadric at all levels:
all bound armor spells and use the duplication glitch. Summon the bound
armor on your body. Get attacked by an animal and kill it. Repair the
bound deadric and you can then drop it. When the spells wear off
collect the armor. The deadric armor will weigh nothing. This also
works with bound weapons.
