Is there a reason this isn't a SimplePropertyExpression?
And I'd suggest adding hit block as well as attached block

Then I wouldn't be able to allow usage of at keyword here attached block *at* last shot arrow

I don't think that syntax is worth it. Personally, it doesn't even make much grammatical sense to me.
If it's the attached block at the arrow, what is it attached to? "attached" becomes a property of the block, rather than a relation between the block and the arrow.
I'd suggest just using the SimplePropertyExpression syntaxes, but I'm not sure if that's the majority opinion.

Either way, you can still use SimplePropertyExpression but with custom patterns.

Reviewing from the phone isn't easy but nice PR ⚡️

@AyhamAl-Ali Discard your requested changes? The expression's base class has been converted to SimplePropertyExpression. Although this kills multi-arrow projectile support in one line.

Just make the type plural.
