At the start of each friendly turn, a model riding a Manticore must pass a Leadership test to control its mount. If the test is failed, the Manticore and its rider are subject to Frenzy until the start of their next turn. Also, should a Manticore's rider be slain, the Manticore is automatically affected by the 'Raaargh!' Monster Reaction result, with no Leadership test or D6 roll.
