Sanctuary:
D6 x D6 % chance for a foe to ignore you during combat.
Example:
I roll a D6 two times. I roll a 3 and then a 6. 3 x 6 = 18%. The item I attach this to will give me a permanent 18% chance to be ignored by every foe that decides to attacked me. I use this crystal on my gloves. Now, as long as I wear them, my gloves will give me an 18% chance to avoid being attacked by any creature. I will check for this every turn from now on. I could get lucky and defeat one or more foes without even being attacked for the entire battle.
Value: 3 Gold per 1% chance.
