5E House Rules

Inspiration: You can spend Inspiration after the roll to re-roll, but not for a crit fail. Have to take second roll. This is not advantage. You have to spend it before the roll for Advantage.

Illusion

1) If you have no reason to disbelieve an illusion, then you don't get to do it.

2) Physical interaction doesn't automatically reveal it is an illusion. You have to roll.

3) If you have a reason, disbelieve is a Bonus Action (rather than action). (Physical interaction would be a reason. That doesn't mean touch necessarily, just interacting. It can be someone else interacting you can see.)

4) If you have a strong reason to disbelieve, then roll with Advantage. (You're buddy tells you it's an illusion, arrows are flying through the brick wall, bard is attempting a second illusion, illusion is really out of place, you spend an Action rather than just a bonus).
