OK here you are Infinity, my final(i hope) Masque rules:
A Harlequin band may choose a Masque to practice before the battle. These masques are taught to them by a Great Harlequin who has knowlage of the masque being taught.
If the Harlequin army is led by a Great Harlequin then you may select a masque to be taught to the band from the following list. Every Harlequin in the army must have the masque, not just single squads or models.
The masques are:
Masque of the Dark Veil at +3 pts/model.
The Great Harlequin uses his or her intimate knowledge of the webway to open a portal at a strategic location on the battlefield, allowing the Harlequins to leap upon their unsuspecting foes or snatch a vital objective before the enemy can reach it. The entire Harlequin army starts the battle in reserve. However, you may roll for units to turn up from the start of the first turn rather than the second turn, as shown on the following chart:
Turn 1 2 3 4+
D6 score to arrive 5+ 4+ 3+ 2+
Before you roll to see which units turn up the first turn, you must nominate a point on the battlefield to be the webway exit (mark it with a counter or coin if you like). Any units which turn up from reserve must move on from that point, rather than moving on from a table edge. You may move the webway exit by 2D6" at the start of each subsequent Harlequin turn (before rolling to see which units arrive).
Masque of the Last Laugh at +2pts/model
The Great Harlequin has trained his or her warriors to lash out at their enemies in their death throes, ensuring that they do not die alone. When a Harlequin is killed in an assault they may immediately make one attack against the model that killed them, resolved using the normal rules. The Harlequin can only ever make one attacks, regardless of how many they could normally make, and may make this attack even if they have already attacked that turn. Once the attack has been resolved the Harlequin model is removed as normal.
Note: This may not be taken by a HArlequin Wrathlord due to the fact that they are already dead.
Masque of the Laughing God at +1pt/model.
It is claimed that the patron of the Harlequins, the Laughing God, saves their souls from Chaos. When the Harlequins perform the Masque of the Laughing God, they call upon him to aid them against the daemons and warriors of the False God of Chaos. Through their ritual dances, they create protective auras of energy around themselves, disrupting the magicks that bind daemons to the real world. The Masque of the Laughing God means that a Chaos player who is summoning daemons to the battlefield cannot place any part of the template within 6" of a Harlequin model (before rolling the scatter dice). See Warhammer 40,000 or Codex: Chaos for more details of summoning daemons. The Masque of the Laughing God has no effect against Greater Daemons possessing models (see Codex: Chaos).
Masque of the Red Death at +2pts/model.
The Harlequins converge on a single point, taking it in turns to leap upon the enemy before withdrawing and allowing another troupe to attack. A Harlequin unit can choose to withdraw from an assault at the end of any assault phase (after all results have been worked out and any morale checks have been taken). The unit simply moves 2D6" away from the enemy unit. This move cannot be used to take the Harlequin unit into a fresh enemy. The enemy unit that the Harlequins have withdrawn from may make a consolidate move. This tactic is most effective when your units work in pairs; one unit charging, and then withdrawing from the fight in the opponent's assault phase, allowing the other unit to shoot and charge the enemy in your next turn.
Masque of the Shifting Shadows at +10pts/squad or Independent Character
The Harlequins dance and weave around each other, creating an ever-shifting miasma of colour. This serves to further confuse and entrance the enemy and makes it impossible to discern exactly how many warriors are attacking. When working out if one side outnumbers the other after an assault, the Harlequins are always considered as many as their opponents, regardless of the facts at hand. If the Harlequins are using Hallucinogen grenades they are counted as outnumbering their opponents 2:1. Note about points cost: Death Jesters pay 10pts per elites choice chosen, not per model, as they are effectively a squad.
