Divinvation
Main Skill/Stat involved ; Willpower
Any associated skills : Yes, the Inner Eye ability.
Inner Eye : Could be redone to provider better odds for these rolls and perhaps +1 usage for the event related rolls.
Example : Say small events allow for one use, a person with the Inner Eye can have two.
Abilities :
In Events - The ability to request a roll to see if your character can use their Divination skill to see a hint of what they are to do in the event or see ahead in the event slightly (Not the entire thing, but maybe the one or two small parts that are to come. The vision would not be accurate, and can be a complete falsification of what your character attempted to see. Can only be used a limited amount of time per event, the moderator's discretion determining that based on event length, or not at all if it wouldn;t apply.
Example : Say a character with the Inner Eye(Or without it) has a quest to find an item in the forest. Potentially there is a chance through using Divination to see where the item is, or a hint as to the right(or wrong) path to the item
Another ability is Divination provides a slight advantage (like the Sneakoscope item) sometimes if the player is going to be ambushed by revealing none/some/all of the enemies before their begin attacking. Not always, less likely that the event related ability but a smaller chance of it occuring. Would probably require two rolls, one to see if it occurs and the other for accuracy. May even be that extremely skilled Divination users could even be able to strike before the ambushers do if they foresaw it.
A more advanced ability idea is that characters who have extensively trained in the arts of Divination may be able to sometimes actively predict a enemy's attacks besides some exceptions such as the Unforgivable Curses and large Area of Effect spells such as Fiendfyre. Would only provide a +1 to evading attacks from the enemy for however long the ability lasts per usage. I would say it'd be hard to accquire as a adult and very difficult for students.
How to do the rolls :
Short summary :
Divination (successful vision) Requires a roll of 2 or less for non-Inner Eye, 4 or less for Inner Eye
Event :
Willpower/ division factor = accuracy . d100 roll, anything less than the accuracy is a successful vision, anything higher is a falsified vision, perhaps later degrees can be added in to how accurate/false the vision is.
Longer version :
As Inner Eye users have better stats for Divination(usually), say the average roll for one without the skill requires a roll of 2 or less to succeed on a d20, which is rather uncommon in rolling. I would suggest the Inner Eye skill adds +2 to that, making it 4 or less required to succeed in the vision.
Then for accuracy of the vision, as of now I think using the player's base willpower and dividing it by an even number before doing a d100 would be reasonable. Using Violeta's willpower of 83 for example :
83 divided by, let's say four for the example : 20.75, roughly 21. Then the mod does the d100 roll and if it comes up 21 or below, it's a accurate vision. If not, it's false. Of course mod discretion as to if a close roll may mean some degree of accuracy is up for discussion as well.
Now using the Inner eye ability.
83 divided by (for example) 2 to represent the Inner Eye ability, is 41.5 or 42 if you round up. Double the odds of a accurate vision.
Only problem I see with this for now is if a player reaches 200 willpower and has the Inner Eye, potentially could be a 100% accuracy while if using the example numbers, would be 400 for non-Inner Eye characters to reach 100% accuracy.
