Action Points rules:
You get 3+Level/Story
These can be used to:
1. Add 1d6 to any 1d20 roll (limit 1 per roll)
2. Avoid 5 HP damage (can use multiple dice, eg 2 AP avoids 10 HP damage).
3. Turn any 1 attack that would normally kill your character into non-lethal damage, essentially dropping the character to 0 HP instead. eg. you get hit for 40 HP of damage but have 10 HP. Spent 1 AP to drop to 0 instead of -30.
