Topic: Help me name this 80s coin op arcade game

I can't figure this out but would love to try finding its name. It's a medieval style game I think main character held a sword but I'm not sure. It's a side scroller and I remember at the very beginning there were two waterfalls you had to jump over; I remember spending all my quarters falling into those falls. More experienced players progressed into castles where rope swings and strategy tasks existed. I remember diagonal slides in the castles where you would slowly slip into a fall, pit, or maybe lava if you didn't time your jumps. Something reminds me of spikes and rope climbs as well. Definitely not pitfall.

I remember the game around the mid 80s and a couple games down was the classic 'tandy' version of Star Wars. This game always had a line of waiters in front of it.

The last I saw the game was in the very early 90s where it still held some popularity. I was able to jump the waterfalls at the beginning much more precisely then.

The game was 8, maybe 16 bit graphics at most. Not golden axe. Definately not dragons layer. It was not Conan or Dark Castle, and I don't think it made it to a console so it was arcade only.

Thoughts?

Black Dragon?

Sounds like Rastan to me.

Arcades in the late 80's/early 90's were an unforgettable experience.

Rastan. That's it! Thank you.
