I was reading these forums about a week ago and someone wanted a way to get to Prince easier.
Start here.
Face east and start jumping.
Once you're here turn around and jump down.
From here, follow the arrows and go up the path.
Keep going until you end up here.
Climb on top of the spike and you should be in Netherspace.
Once you're in Netherspace face west and start climbing the mountain.
Once you're here you can jump to Prince.
Tada. You're done.
You can get past Prince as long as you wait for him to Pat away from the door. If you're trying to solo chess there will still be stealth seeing mobs so you'll have to haul ass to get past them.
I hope this isn't a repost, anyways; Enjoy.
