Moon runes and Barrel escape. Haven't made it to the end of 5 Armies, so not sure of that one. Very cool in moon runes, except don't stack it with Smaug multiball because can't score off ramps because of diverter.

Good point on the Smaug stacking, I’ll keep that in mind.
This diverter is one thing that Keith could code in a bit more. Maybe even a mode where you need to get the ball down the wireforms, and the ring button will change the position of the diverter. You need to pay attention to it’s position, hit the button (or not) and make your shot accordingly. Final wizard mode maybe?

How does moon runes work? I haven't been able to find it in any of the rulesheets...

It’s just a mode. Shoot the ramps. The diverted sends the ball back at your flippers back down the ramps. 5 or six shots completes the mode if I’m remembering correctly.

Also my favorite 4 star mode, where you have to defeat Bolg's right hand man...er, orc. You hit the ramp and it tries to make you drain by throwing it back down in your face. It isn't used often.

Edit: oh shit, I see this is a two year old post that got resurrected. Somehow doubt op has been wondering about this for 2 years.
