Rules clarification...on Maegan's card it says all units at range 1 - "red rune" from the defender...

Does that mean the range is only whatever the red runes are at the time (one per red rune, 0, 2 or 4)?

Does that mean from range 1 OR whatever the red runes are (1, 2 or 4)?

Does that mean 1 including the red runes (1,3,5)?

Thanks for the insight.

1-0 is always at minimum 1. So within ranges 1,2, and 4 respectively are all possible. Remember anything within 1 is also 'at 1'
