Re: what do people think of Epic-6?
Why does the level 15 rogue need challanging locks to pick? She's been there, done that, got the t-shirt (and the loot).
At the point of being a demigod, there shouldn't be any locks that give her trouble, and the lack of them helps keep her skill in perspective. She is a demigod, not some level 5 but with higher numbers. How can you feel like a demigod if nothing ever becomes easy?
At the point of being a demigod, she should be looking at becoming skilled in other things now that she has mastered locks.
To me this sounds like expectations are remaining static while the numbers grow. Sounds like you want the experience and difficulty to remain the same and to keep facing the same types of things despite refluffing them as different.
But really, trying to achieve that while leveling up to 20 is basically ignoring what those higher levels mean. Do you think Sauron faces challanging locks? Does he worry about the same things a bunch of level 1s worry about? Of course not!
Being high level doesn't mean facing more difficult versions of the same things, it means facing entirely new types of challanges. As such powerful beings everyone and their grandma looks to the PCs. Some with worship, some with fear, some see them as people to manipulate to achieve their own ends, others want to make them queens and kings, etc.
The challanges faced by high level characters should not be locks or tracking, it should be the need to be in many places at once, being targets of entire kingdoms, assasination attempts, etc. When you are a demigod, you are like Hercules, everyone recognizes your power and wants to either be touched by it or to influence how you use it.
You pass through town, people don't go "Hey look, adventurers!" rather they act much like Bilbo when Gandalf first came by offering adventure, people are amazed, honored, and/or terrified.
If you keep trying to make locks a challange to high level players, then the game has not advanced and thus has been eclipsed by the advancement of the characters.
