There are two rules that I have a hard time finding a straight answer for.

1. Do all monsters have 3 attack range? It feels weird that a zombie would have the same range as a hired gun...

2. Would a monster move past or away from an investigator? Such as, a monster moves to the character with the least clues but I'm sharing a space with the monster and I dont have the least clues.

1. Most monsters attacks require you to be in the same area as the target, the APP handles this stuff and explains how they target.

2. Yes; though obviously it only considers targets within its movement range to be valid options so it won't ignore lower rated targets for a better target it can't reach - so no kiting...lol
