You're welcome to test them, of course. I always appreciate feedback.
I made you an arrow rather like the explosive one, but with a concentrated acid in the ball rather than black powder.
There is also an arrow that creates a bright light and loud noise in order to disorient opponents. It should be good if you need to escape a situation.
And there's an arrow that explodes into shrapnel, rather than a traditional explosion, for better piercing damage.
