Wardens like lapis lazuli

It will be cool if the warden will like lapis lazuli. While it attacks you you can give him lapis lazuli, hopefully it will accept it as an apology gift and leave you alone. 

Giving a warden 1 lapis will have about 5% to calm the warden and lapis lazuli block will have about 20% to do it.

While the warden is calm it will not be hostile for a minute but if you will try to attack it it will get angry again.

The warden will also try to break and collect lapis, but unlikely to piglins lapis will not distract it while it attacks.

The warden's love to lapis might save you in warden situations and give you a reason to mine more lapis.
