First, start with a life warrior.
Go into his inventory, and you will see he has a staff.
If you repetadely put the staff in his hand and put it back in his backpack, te defence will rise up.
Eg.
Take staf from hand, put in backpack
Take staff from backpack, put in hand
Take staff from hand, put in backpack.
You get the idea?
After about five minutes of this, you can get up to 500 defence points.
