Currently working out how rules work with hill and leaderpoints and cover requires checking at least 3 places in the rulebook and deriving how it works, rather than a single rule.
I’ve come up with this to keep it clear in my head - does this look thorough?
“If an attacker is shooting at a unit that has its leaderpoint on a hill, and the target unit is not on the hill, and more than 50% of the line of sight to the facing being attacked passes over that hill, the target unit has cover unless the attacker is 3 units of height taller than the hill the target’s leader point is on.”
