[solved] Need 3 Skill Challenges for Tomb of Abysthor

[Obergnom]

Hi there,

for my current Tomb of Abysthor Campaign, I need three skill challenges, to lock the players out of certain parts of the dungeon, until they are high enough in level:

A Brass Door secured by evil clerics with the help of magic as well as a very complicated lock. WIthout the prober key, they should not be able to pass this before they reach level 6.

An underground stream in a cavern with a lake. They should not be able to swim through or reach the other side before they reach level 8.

A corridor with a powerfull evil rune, summoning a guardian if they get to close. At the end of the corridor there is a door. This challenge should not be overcome before they reach level 6.

I'm currently at a complete loss how to achieve this...
