This was mentioned for a short time in the wishlist thread, however I don't think that it went into enough detail for the subject and I would like to make it a finished product so that it can be used with friends.
The Court of the Young King would allow for Exarchs of different aspects to be taken together in one unit.
General ideas of mechanics are that the Exarchs could still purchase their powers as normal and that they would apply to the whole squad if the buff functions in that way. The major problems with this idea are that some aspects just wouldn't mesh with the others in any way what so ever such as shining spears and dark reapers and that some of the Exarchs best equipment would become obsolete when they join and so make them far less likely to be chosen such as the other Fast Attack aspects.
To fix this, we would have to merge the Fast Attack special movement rules into one set. This would be "The model may move as if equipped with a jump pack, before or after it shoots, or may choose to increase its movement to 18" in lieu of shooting. If the unit assaults, it may only move as if equipped with a jump pack that turn."
After this, The Fast Attack Exarchs need to be able to work with the others, so rather than crippling the Fast Exarchs, we would make it so that when one of the Fast Exarchs is chosen, they recieve the option to equip the rest of the squad with a piece of equipment that allows them to travel at the same speed, whether this is a pair of wings, a warp-jump generator, or a jet-bike, This would make the entire unit follow the rules outlined above. This ability would be very expensive.
Next, there is the Dark Reaper, which suffers from being stationary and long ranged. To make it able to function in this group, we would allow it to make its weapon assault (regardless of what that weapon may be) for another 10 points.
Finally, there is the Fire Dragon, The Fire Dragon is unique in that it would be uninterested in the normal prey that this unit would seek out, and so would be far less likely to be chosen, To fix this, we would allow ANY model in the unit to fire at separate targets. The unit would still be forced to assault a single target and it would have to be one that was shot during the shooting phase as per 40k rules.
The rule juggling section is finished, on to statistics.
Fluff states that the Court of the Young King is composed of the deadliest Exarchs available. Exarchs are already one-man armies in their own right, so the deadliest would be monstrous, to represent this we would increase every Exarchs WS and BS by 1 so that they would all be above the Average Exarch.
Other than this, the Exarchs would all have the standard Exarch stat line.
Here is what it would look like
Court of the Young King
May be taken only if an Avatar is fielded. Does not count towards FOC.
Squad size: 3-10 Exarchs
Exarch: 28 points (no exceptions, Cost for wargear, rules, and movement options are added onto this figure.)
WS X+1 BS X+1 S X T X I X W X A X LD X Sv X+
Fleet
May purchase Powers correlating with its aspect for the original price, powers affect the entire unit.
May purchase wargear correlating with its aspect for the original price.
Comes with wargear possessed by an aspect warrior of their aspect.
Wargear that affects movement will be considered obsolete, however an Exarch with movement enhancing wargear is allowed the option to outfit the entire squad with wargear to keep them up to speed for 20 points a model. Note: This is only possible due to the Exarchs extreme skill at navigating with his device and is capable of guiding the entire group with them.
If the unit is outfitted in this way they follow the Court Special Movement rules shown below.
May choose shooting targets separately from unit however must assault with the unit and may only assault a unit that was fired upon by at least one member of the squad.
No Aspect may have more than two Exarchs representing it in the Court of the Young King. (This is not council of the Banshee or council of the Spider)
*Dark Reaper Exarchs may upgrade their weapons to assault for an additional 10 points.
Court Special Movement- The unit may move as if equipped with a jump pack before or after it shoots, or may choose to increase its movement to 18" in lieu of shooting. If the unit assaults, it may only move as if equipped with a jump pack that turn.
So, what we have here, is a unit that has a ton of special rules for itself, and can cost upwards of 500 points, easily making it one of the most expensive units in the game. This squad can be geared out to be all purpose (anti-tank, anti-mech, anti-horde) and transport itself across the field without a transport (shadowstrike or Movement wargear deepstriking) and will hit like a train. However this unit has nowhere near the survivability of terminators or the seer council and can be annihilated in one turn of concentrated fire. This is a unit that from the fluff would genuinely deserve the title of deathstar, and pays through the nose for it.
Any suggestions are welcome however if all you are going to do is say it is crap please do not comment.
