Due to traumatic experiences, you now have the ability to see visions of the past, present, and future. Once per day, you must beat a WIS saving throw to avoid having a vision. The DC is moved up with more intense visions starting at a DC 6. When a vision occurs you will roll a D20 to determine which kind of vision it will be. It could range from seeing what the meal at the tavern will be to seeing a location of a needed item to uncovering secrets locked in the past. Visions can be forced with a DC 13 WIS save. However the more you force the visions the more likely you are to cause harm to yourself in a myriad of ways. Once you have had a vision, you will not experience another check until your next long rest unless forced. 

D20 for vision range. 
1-8: Visions of the past 
9-17: Visions of the present
18-20: Visions of the future

Forced Vision Punishments: 
1-3: Levels of exhaustion, escalating each time
4-6: Temporary scars (i.e. for 12 hours you cannot feel your extremities. Disadvantage on DEX checks and saves)
7+: Permanent scars( Roll a D20 on the lingering injury table.)
