The Gnasher model part can make Supporting Attacks even though it has Harnessed. The Goblin Rider model part cannot make Supporting Attacks. Gnasher Dashers gain Impact Hits with the following exception: instead of causing a number of hits per Charging model, a Charging unit of up to 5 Gnasher Dashers causes D3 hits to a single enemy unit in base contact with the unit's Front Facing, while a unit of 6 or more Gnasher Dashers inflicts 2D3 hits instead.
