It may be worth including a section discussing the effects and costs of prayers.
The PC is only required to visit the pyramid and the maze for the first time during the specified level periods. Once the PC has visited those areas once, they may return at any level. This means that PCs should always have the opportunity to visit the pyramid, since they may simply enter at level 13, leave right away, and come back when they feel strong enough--even if that happens to be level 25.
On D50, I believe it is only necessary to kill the Balors on the level to ensure the gate remains closed.
[edit]: On a more extensive note, I would love to see the monster table include information such as which monsters see invisible, see in darkness, elemental resistances, and what types of slaying ammo they are vulnerable to.
