Weapon Blessing Questions.
 

I was just wondering a few things.
1. Which god's will double/tripple/etc. bless a weapon? (add the +1, +2, etc to the weapon)

2. Will a god still bless a weapon if you have used prepare weapon on it and iwd?

3. What are the max +'s a god will bless a weapon with?

2. Yes it will still be able to be enchanted
3. I tihnk its +2 but im not sure
