My players are about 17th level rightnow. I plan to take them all the way to and through 30th level (Quicksilver Hourglass). To help get them there, I invented a this island. It's a typical lost island. No one returns, very dangerous, etc. Original I know. But, I'd like some assistance filling it with horrible things to challenge them, especially of the Epic quality. I'm hoping to land them on the island at or around 21-22 level. With that, I'm hoping to achieve 4-5 levels out of this "module." I'm using a huge map, The Dungeon Under the Mountain (level 1) pdf, I downloaded earlier today. So some epic style traps would be cool too.
The island is billed as something filled with powerful magic items and rare gems and cool treasures. Well, it is. But, primarily (because no one really knows) it's a dumping grounds for the gods. Bad ideas, goofy magic, messed up monsters. A place when you cast the banishment spell, some have been banished to. So... any ideas???
