Gambler

You are given 5 chance points to start - increases of points by one happen every 3 levels

Use your points to add extra damage, increase hit modifiers, give advantage, whatever you see fit. However- each point has a 20% success rate, you can use more points to increase the success chance (2 points is a 40% success rate). On success, whatever the player declared in the moment of use will happen at the gm's discretion, on a fail however, roll a d4 to find out your consequence.

1 = exhaustion point

2 = trip and fall prone

3 = event happens to unintended target

4 =  1d6 psychic damage

5 = lose a possession

6 = the thing you wanted doesn't happen, that's all
