Wear heavy armor without sufficient strength:
If you have the Bless spell and an Ylside armor, you can put it on them even if you 
are in the 10th level of Strength. Use the Bless spell (your level of magic is 
important at this point) and put on the armor and weapons. When the spell ends, 
you can still wear the armor. 

Bonus items:
After breaking out of your cell, kill the Goblin and walk to the table. Look at the 
pile of garbage in the corner. Take the bone on the left (in the pile of vegetables) 
and use it on the chair ten times to get new items in your inventory.
