For example, if an archer character enters a well lit room that is 100ft long, 25ft wide. The last 25ft of the room is completely filled with 24 zombies, one each square surrounding a Ghast.
Questions
1) Can the archer shoot the Ghast even if 4 zombies may be in front of him. Will the Ghast just receive a +4 to his AC
2) Could the Ghast decide to crouch / hide to prevent being hit by arrows.
3)Could the Ghast aim a spell at the archer, or would the 4 zombies in front block the spell attempt.
4) If the Ghast was behind Large creatures like an Ogre, would this make a difference
