Controls how all creatures attack or block
A rule for every creature in combat: creatures can't block (Bedlam, Falter), creatures with flying can't block yours (Bower Passage), all creatures attack or block each combat (Grand Melee), you choose who attacks and blocks (Master Warcraft), or players may attack only one neighbor (Pramikon). Limits on attacking you (Moat, Ghostly Prison) are role:player-protection.
