Same WIZ cost, etc.
The basic shift is that 'you get a feeling'. Is that feeling always right? No way, Jose.
Player - 'Will I die if I go into this dungeon?'
GM - 'You get a queasy feeling and feel it is not going to be a picnic in the park.'
GM - 'You feel good about this, on top of you game, you know nothing is certain but you feel you can march and overcome anything you might meet if you stay sharp and keep your wits about you and have a slice of luck!'
The GM secretly rolls either 1d12 or 2d6 (rolling a total of 4, no DARO, gives the same 1 in 12 chance) - if 1 (or 4 for 2d6) comes up, the GM feeds a misleading feeling with no hint of that to the player.
Player - 'Will anyone be a higher level than me in this dungeon?' (The player is L6.)
GM - rolls 4 - 'You feel that you are going to be the top dog and anyone in their right mind would run from you all the way back to their mummy.' (GM knows there is a L10 wizard down there, just waiting.)
