Ok, so here goes the final part. Effigy of Excess & some general stuff. Still not sure about some elements, but discussion & playtesting gotta start somewhere. 
First, army rule:
Number of Slaanesh
Six is the magical number of Slaanesh and his followers often form groups of six or multiplies of six in hope of pleasing their number this way.
At the start of each Cult’s player turn check which units consist of six or multiply of six models (including characters; multipart models, such as cavalry still count as one model). These units gain favour of Pleasure God until the next Cult’s player turn. Units with Mark of Slaanesh and Daemons can subtract one from their roll during break(/instability) tests. Unmarked units can subtract one from their roll during fear, terror and panic tests.
As mentioned earlier, I wanted to implement the idea of 6-ish units gaining an advantage, but at the same time I wanted to keep it small, not to break overall balance.
And now
EFFIGY OF EXCESS
First some theorizing, to show reasons behind my ideas. The general idea was that two of ‘component armies’ of SoC have something similar in fluff/function to EoE (Dark Elves – Cauldron of Blood; Warriors of Chaos – Chaos Warshrine), so I used those entries as a point of reference.
1.Slot- CoB is a character ‘mount’, while Chaos Warshrine is a rare choice. I believe EoE should be a character (specifically, Sorceress and/or Supreme Sorceress) upgrade like the former. That’s because of fluff reasons (Sorceresses are leaders & priestesses of the Cult, so it seems natural that one of them should overlook an Altar) as well as balance/variety reasons (with removing of big monsters, Cult characters have shortage of non-1W mounts).
I also kept at the back of my mind the option of making EoE both given limitations if it turns out powerfull enough to need that (so character upgrade taking additional rare choice).
2.Main Function – CoB main use are it’s Blessings – useful, controllable and long range. The long range is also useful to protect CoB from entering HtH combat (so does it’s Terror-causing), as while it’s much better in close combat than normal warmachines, it still has little chance against regular/elite CC-oriented unit.
Warshrine on the other hand, with it’s combined stat-line is extremely resilient, keeping it safe in CC. It’s blessings however are short-ranged and random, so they’re not as useful (unless you bring multiply Warshrines).
Now, with EoE, I wanted to keep randomness of blessings for fluff reasons, so even if given longer range it needs some other focus. Making it resilient would be against spirit of elven&slaaneshi armies, so I decided that the aim would be making it lethal in HtH, while still fragile.
3.Stat line & crew rules – for the function given above Warmachine-like treatment seems like a better choice than one combined profile. To give EoE both a chance in harsher CC and to keep in line with ‘Number of Slaanesh’, I decided to go against the usual route of two ‘crewman’ and instead make it five (for a total of six, including the Sorceress).
As it’s a small unit, that cannot be made bigger or given CG, I wanted to make it supreme-elite to compensate for that – a kind of ‘Devoted Chosen’. Therefore I gave them all Devoted Champion stats & Quickening Blood upgrade (the ASF was IMO needed to cover the fact, that this unit includes fragile spellcaster).
Other than that it follows ‘Attendants’ rule, like CoB.
4.‘Aura-type’ bonus - CoB makes Khainite units Stubborn in 12”, Warshrine gives Eye of Chaos rule to all Champions on the table. The second solution doesn’t IMO fit Cult’s army, but the first one seems appropriate, so I decided to keep it (only changing Khainite to units with MoS and Slaaneshi Daemons).
5.’Blessing-type’ bonus - As mentioned above, I wanted to keep basic randomness of the blessing. However, to make it a bit more controllable I decided to give it longer range and allow re-roll (re-roll only goes to units following ‘Number of Slaanesh’ rule to promote it a bit more).
Of course the original Eye of Chaos table isn’t always suitable for Slaanesh, so I decided to make ‘Eye of Slaanesh’ table instead. Other than it’s use in EoE I think Anointed should roll on it after challenge/monster victory (similar to WoC characters).
6. Ward save - Both CoB and Warshrine get 4+ Ward save, so I gave one to EoE crew also.
7. built-in’ crew saves/special rules - CoB gets EH, Frenzy, Khainite and Poisoned Attacks, Warshrine gets Will of Chaos and 4+ AS. In both cases it comes from the rules of crew (Hags in one case and – supposedly - Chaos Warriors in the other).
Following that, EoE has: EH, Mark of Slaanesh, Narcotic Fumes and Quickening Blood rules.
8. Other rules - Warshrine gets no other rules; CoB gets Magic Resistance (1) and Terror.
In case of EoE I think Terror cannot be justified – Slaanesh is a bit ‘friendlier’ god; still, it’s an otherworldy altar of Chaos God, so Fear would fit IMO. Looking at Warshrine removing even Fear is also an option, but I’m keeping it for now.
No reason for MR on EoE, but I think it would fit nicely the Cult’s Daemon Summoning rule to grant 1 additional Summoning Point for including Effigy in the army.
9. Cost - That’s where it gets tricky. I tried to calculate the costs of both CoB and Warshrine by regular means (that is, compare how much similar rules/stats cost on other entries/items), but it turned out that this way CoB should cost about twice it current cost and Warshrine should cost 10 pts more + whatever the cost of it’s blessing should be.
So I decided to compare rules of CoB and EoE (as these two have more in common) and check how much that speculative part-by-part cost of both would differ. What I came up with was 25 pts higher cost in case of EoE, though not taking into account lesser usefulness of it’s blessings. So I decided that 10 pts of real cost (the one in the army list, not the speculative part-by-part cost I was speaking about above) cost more than CoB would be ok.
Ok, so that’s enough of theorizing, here are the rules themselves:
EFFIGY OF EXCESS - 120 pts
may be taken by Supreme Sorceress or Sorceress instead of a mount. Takes additional rare slot.
Devoted Champion (or maybe Chosen Devoted instead?)
M WS BS S T W I A Ld
5__5_ 4_ 3 3_1 6 3_8
Special Rules:
Eternal Hatred, Mark of Slaanesh, War Machine, Fear, Narcotic Fumes*, Quickening Blood*
*see Devoted entry
Attendants – The Sorceress, the five Devoted Champions and Effigy of Excess itself are treated as a unit, though they are deployed at the same time as characters. The attendants form the first rank, with the Effigy model placed behind them in second rank. All shooting and other ranged attacks against Effigy of Excess are resolved using War Machine rules. Effigy gives its attendants a 4+ ward save and itself cannot be damaged – ignore any hits allocated against it. If its attendants are killed it is removed immediately.
Glory of SlaaneshAt the beginning of his own turn (after all Psychology tests are taken), the Cult player may pick a single friendly unit within 24”. The unit may immediately roll on the Eye of Slaanesh table – note the effect generated down on your army roster. A unit under effect of Number of Slaanesh rule can re-roll the first result, but in that case the second result must be kept. At the beginning of subsequent turns, the Cult’s player may choose to roll again to get a more desirable result or choose another unit within 24” to be blessed. In both cases it will negate previously generated effects. Note that if there are multiple Effigies present, a unit can reap several rewards in this manner during a single turn.
Altar of Slaanesh – All units with Mark of Slaanesh and Slaaneshi Daemons within 12” of Effigy of Excess become Stubborn.
*Battle Standard Bearer – One Sorceress overlooking Effigy of Excess or one Master in the army may carry the Battle Standard for +25 pts. If a Hero is carrying the Batle Standard, he can have a magic banner (no points limit), but if he carries a magic banner he cannot carry any other magic items.
THE EYE OF SLAANESH table (most gift names not created yet, so I’m only giving effects)
2D6 Roll – Gift of the Pleasure God
2 - Stupidity for the rest of the game
3 – Initiative 10 and gains Always Strikes First
4 – enemy units in base-to-base contact get -1 Ld modifier
5 - +1 Attack
6 - +1 Movement
7 – No effect
8 – Poisoned Attacks
9 - +1 Ld
10 – Fear; if the unit already caused fear, it now causes Terror
11 – 5+ ward save
12 – Stubborn & 4+ ward save
VARIANTS & IDEAS
1. Not sure about order of bonuses in EoS table, it may change
2. I considered allowing also Supreme Sorceress with EoE to be BSB. Fits well fluffwise, but not sure about it rule-wise.
3. I also considered giving EoE War Machine rules - the main difference is it its current version it's allowed to charge. If given regular War Machine restrictions (making it more similar to CoB), I think we can remove ‘takes additional rare slot’ part.
4. As mentioned above, I’ve also considered removing Fear, though probably only if playtesting shows it’s needed.
5. The cost is also subject to change; as I already wrote, it was hard to establish on paper.
6. This version of EoE means Sorceress is likely to end up in CC. So I think including some protective item in Slaaneshi Magic Items would be nice (though nothing powerfull – I was thinking of something like ‘enemy must pass Ld test to attack bearer; otherwise they must allocate their attacks against other models in b-t-b contact’ or something similar)
7. As noted before, I think Anointed should roll on the Eye of Slaanesh table after slaining an opponent in a challenge or a monster.
Ok, so that’s all, unless I missed something there are rules for every entry now. Waiting for comments (especially from you, Kyrel & MA – if you’re still here ). Also, anyone interested in playtesting this version of the list – let me know, I’ll send you a compiled set of rules as soon as I make it (should be in about 2-3 weeks).
[Edit: changed the rules of EoE a bit; also included cost I forgot to write the last time (though it could be deduced from comments).]
