There will be plenty of times while playing Carnevale when a character’s movement puts it in a place it could theoretically stand, but the miniature’s base prevents it because of terrain. For example, a character climbing to the top of a building that ends up on there, but not quite far enough to balance properly.
In these situations, remember the Golden Rule! It’s always best to allow your opponent to make these slightly riskier moves, and half an inch of movement doesn’t matter as much as performing an exciting feat, or as much as a lovingly painted miniature falling to the floor!
When climbing to the top of a building or Jumping a gap for example, if the character just about makes it but can’t be placed, simply Move the a minimum distance until they’re safe and sound. If this extra distance moves them into base contact with an enemy, so be it!
