Armour that takes a share off physical hits, lifted from the tower-defense slice's content\td.ledger (Armoured) and its brute from content\creeps.ledger. Armour takes Armor / (Armor + 100), at its own stage, off a hit carrying Physical, carried by an ability tagged so or a host's deal naming it; a poison's passes whole. 150 lets 40% through.

make bt Brute
deal 10 to bt Physical
expect bt.Health = 86 from content: 10 x 100 / (150 + 100) = 4 off 90

deal 10 to bt Poison
expect bt.Health = 76 from content: no Physical tag, so the armour takes none: 86 - 10
