Dragons and Ents have bespoke movement, attack and vulnerability rules.
How it works
Dragons fly 24" or run 18", can land on a figure to crush it (saved on 5-6, the survivor then runs two moves), and are hurt by missiles: per hit roll 2d6, 11-12 kills, 9-10 turns it on the other side, 2-3 enrages it to breathe flame twice. Ents move 3" (6" charging); Sauron's figures coming within 6" of an Ent or Ent-controlled tree roll to survive (Orcs survive on 1-2, Men on 1-3); Ents are immune to death and morale in an Entwood.
For each hit by such a weapon, cast two dice; a roll of 11 or 12 will kill the dragon, a cast of 9 or 10 will drive the dragon to attack the other side on the next turn
