The description for Mindshackle Scarabs on page 81 states, "... If the [3D6 Leadership] test is failed, the victim strikes out at his allies. Instead of attacking normally, he inflicts D3 hits on his own unit when it is his turn to attack. ...".
For example, the infected victim is a Nemesis Dreadknight. (The Nemesis Dreadknight is an example of a Monstrous Creature which only exists in an unit of one. One could substitute the Nemesis Dreadknight with the last Guardsman in an unit.) Does the Nemesis Dreadknight attack itself in close combat? I feel like I am overreaching if my answer is yes, so I have to say no. However, the Nemesis Dreadknight still does not get to attack normally after failing the 3D6 Leadership test, that is, the Nemesis Dreadknight does not make any attacks in close combat on test failure.
For example, two Lords each with Mindshackle Scarabs are in base contact only with one Assault Terminator of a five-Terminator unit. Does the Assault Terminator have to make two 3D6 Leadership tests for infection? If the Assault Terminator fails both, then does the Assault Terminator make one set of D3 attacks, or make two sets of D3 attacks, against the other Terminators in the unit? My answer is yes that the Assault Terminator has to make two 3D6 Leadership tests for infection. However, I feel like I am overreaching if my answer is two sets of D3 attacks on the failure of both tests, so I have to say one set of D3 attacks. Thus, the selected target of multiple Mindshackle Scarabs has to make a 3D6 Leadership test for each selection, but only incurs one set of D3 attacks regardless of the number of failed tests. This is my interpretation to be fair with vague/incomplete rules.
The description for Mindshackle Scarabs on page 81 starts with, "At the start of the Assault phase, after assault moves have been made, but before any blows are struck, ...", and ends with, "If he is still alive, the victim returns to normal once all blows in that round of combat have been struck."
Does the test and effect of the Mindshackle Scarabs repeat each Assault phase with the carrier of the Mindshackle Scarabs in base contact with the enemy, even though no "assault move" has occured in the Assault phase? My answer is yes, because the rules only describe a point in game time using using game events as the boundaries, and do not state an "assault move" as the game event necessary for the trigger of Mindshackle Scarabs.
