Hi,

I am trying to do level kelvintaph burgler but I keep getting an error message saying that paladin.canCast is not a function.

I am not sure why this isn’t working as I’ve used this before so it should do.

Any ideas?

Man thanks,

The code I’m using is below the screen shot

I don’t have BS4 now but when I did, I didn’t pass `paladin` as a second parameter in the if-statement. Try removing it.

All these return a list, if you want to try to do something like `attack()` or `canCast` while using them as a parameter, it will throw an error.  
You must put a [0] to turn it into one enemy.

I was being an idiot. I thought that because there was just 1 paladin it would return a single item. But it’s still an array.

I haven’t tried your solution out yet but I’m sure you’re right

I did the same thing for witch and chieftain. Normally after doing a find I’ll loop through with a for next and don’t usually think of finding a single one at a time.
