How to make a sword that gives effect to player when hitting mob.

I'm pretty sure it can be solved using Procedures. Try exploring the coding blocks, and tell me if you can or can't find a way to do it.

yeah ... that is my problem too... anyone can't help us ?

I have made new procedure that when mob is killed with a chosen item in main hand it will give the player effect but for some reason if the item loses duration it will no longer give the player the effect. So if any of you know how to make the effect work even when the item loses duration please tell me. But this will work with item that does not lose duration.

just do when mobs hurt with tool

execute command /effect and the effect you want

Could you please show me a picture of the procedure? I tried multiple things with the execute command thing, but I cannot get it to work.

vanilla commands

for 1.14:

/effect give @p resistance 100 2

gives resistance II for 100 secs

I know vanilla commands ;D. I went to the tool procedures menu and picked "When mob is hit with tool" and added "execute command" procedure and added the "effect command", but in game when I hit something with it id does not give me any effect. I tried multiple ways to do it but nothing seems to work could you please make the procedure your self and post a screenshot It would be very helpful?
here are some ways i tried to do it but they didn't work: https://ctrlv.cz/XG3D

no

you first create a procedure. then you go to your sword menu and go to triggers. there you can put your procedure in *when living entity is hit with tool* hope this helped you I was searching for that for a bit of time xD
