As the Overlord, I often face the problem of how much and when to reveal information to the players.
For places with different Areas, I normally read out what's in the grey box of the Area but do I need to inform players of the different traps and stuff available? And if so, do I reveal right from the start or when the trap occurs?
For example,
(1) Road to Legend Dungeon #30
Do I let the players know that when they step in squares marked with 'X' they get webbed? Or do I wait till the first player steps into one before revealing it to them?
(2) Road to Legend Dungeon #12
Do I inform the players they have to end their movement on the throne? Or do I wait till they realise the master Giant does not unlock the rune-locked door and let them devise their own solution to opening the door?
These are just some examples of the issue of how much information to reveal to players and also the timing. Please help. Thanks.
