Item of forecasting (Sort of helmet, or similar item)
The idea is simple, it's like an intuition spell only that is not a general idea, its like playing for real without dangers.
When you activate this item, you have to control your power points, hit points, experience points, everything. Then you start playing, like normal game, but this items works like saving the game as videogames. You have X time to advance the game, being sure that you can't die or make a big mistake. At the end of that time, usually (we will see later the options) you come back at the place and situation where you were at the time of activating the item. You will remember everything, you can also with good memory draw a map, or remember specific details that can come important later in the game. The caster will be the only person with this info, probably other players had played this alternative reality, but they will have to play as if they don't know anything.
Note that caster is aware that he is in a forecast reality so he can risk more , because he knows that he can't die. If he dies while in forecast reality , everything will resume at the origin point no matter what, even mind-altering spells on caster.
Options recommended: Spell only once per day or week. Not more than five minuts of forecasting. Rolls can change this forecast reality and real game, so you will see and remember for example when you try to cross swiming a river that there are animals hidden, but maybe sometimes you roll enough to swimm and sometimes you will not. The caster will not gain any experience points, hits, or lose power points at the forecast reality.
Options for GM: If the forecast result satisfactory, GM can allow the players to accept this reality exactly, and don't force the players to repeat everything again.
Allow other players to remember what happened in the forecast reality in order to play it later. Some players will argue that they are true living and learning with this experience , but i will not allow them to earn the experience points.
it gives players a way of being succesful in difficult missions without powerful items.
Hope you liked.
