What do you think makes a good battlemap?
There isn’t a one size fits all set of rules, but I like:
- multiple exits and entrances. If the party needs to flee, or there are reinforcements, then they’re should be a few ways on and off the battlefield
- cover. A scattering of solid items to use as full or partial cover makes it easier for characters to move.
- multiple paths allow units to circle behind enemies.
What do you look for in maps?
When I play that type of scenario I avoid using a map. Mostly because I take hours to create a map (which is pretty frustrating), but also because it’s too restrictive. If the players ask about something clever, I want the latitude to include it. Your example of the secret passage is a great example of the later.
