So I (war cleric) and my friend (paladin) want to use [*warding bond*](https://www.dndbeyond.com/spells/warding-bond). It says:

> 
> [...] While the target is within 60 feet of you, it gains a +1 bonus to AC and saving throws, and it has resistance to all damage. Also, each time it takes damage, you take the same amount of damage. [...]
> 
> 
> 

So the questions are:

1. If I cast [*sanctuary*](https://www.dndbeyond.com/spells/sanctuary) on myself, does the enemy who attack my friend have to roll a saving throw first before it hits me because of *warding bond*? Or does *warding bond* nullify the *sanctuary* effect on me?
2. Is it okay to cast healing spells inside the *sanctuary*?
3. If I have the defensive duelist feat, can I use my reaction to nullify the attack I got from *warding bond*?
