No. Chaos armies are not exempt from the main rule that the character with the highest Leadership value must be the General.

Yes they can. From Page 102 of the main Rulebook "Any unit within 12" of the General model may use the General's Leadership value instead of its own when making a Leadership-based test..." On page 29 of Hordes of Chaos while discussing Instability tests it states "Roll 2D6 and compare this to the daemons' Leadership value, with no combat resolution modifiers..." Nowhere in Hordes of Chaos does it state that the General's Ld value may not be used and in fact the specific wording used by the design team (as shown above) makes it clear that daemons may use the Ld value of the General for Instability tests.

No. Daemons don't get the benefit of the Battle Standard Bearer re-roll due to the instability test *not* being a break test (Instability test is made instead of a break test).

Yes.

No.

Slaanesh: 6; Nurgle: 7; Khorne: 8; Tzeentch: 9.

Yes.

Both units inflict and take damage. In the example of the Fanatic, the Screamers take D6 S5 hits and simultaneously each do a S3 hit on the Fanatic.

Chaos Warhounds have a unit strength of 2 each and as they are not classified as "Fast Cavalry" they do receive a rank bonus.

It is bound by the normal rules for shooting. If there is a unit which can be reached by both breath weapons, the Chaos Dragon cannot Divide Shots. Otherwise (i.e., no unit can be reached by both breath weapons) the Divide Shots rule applies and the breath weapons can attack different targets.

In Warhammer Chronicles 2004.

Yes they do. On page 40 of Hordes of Chaos change the wording "After that they are free to move as they like, and they count as a separate unit for the rest of the game" to "After that they are free to move as they like, and EACH counts as a separate unit for the rest of the game."

Yes.

Yes.

No.

No. Only a mortal character with the Chalice of Chaos (which makes him a daemon) may join a unit of daemons. Non-daemonic models may not join a daemonic unit.

Yes. A daemonic steed may be joined to a mortal unit, as long as the mortal chaos character riding the steed is alive.

At the end of the phase in which the mortal Chaos character is killed, the daemonic steed is separated from the mortal unit (you might like to place him 1" away to make sure this is clear). If the daemonic steed is involved in combat when the character is killed, place it so it remains in base to base contact with the enemy. In addition, remember to take a Slain Rider test and generate a Monster Reaction if the test is failed.

No.

Both. The rule states "Any unit in close combat with one or more models with a Cloud of Flies suffers a -1 modifier on rolls to hit."

Yes it can.

No.

No. He can still get other mortal magic items though.

No. Per the Errata printed in Warhammer Chronicles, the bearer can make a single re-roll of one or more dice rolled to cast or dispel each spell.

The attacking player rolls to hit and re-rolls misses. Then the defending player makes the attacker re-roll all successful attacks.

Yes.

Yes.

Yes it does.

Just a normal spawn (not that any spawn is really 'normal'!)

The character may ride on a Chaos Steed or a Daemon Steed, but may not ride a Chariot or a Dragon of Chaos.

Caster's choice.

The caster chooses which weapon to attack with. The Swordsmen will defend themselves as best they can though, so they would use their shields. However, if a unit was armed with halberd and shield, the caster may choose for them to attack with the halberd, so they could not use their shields to defend with, as they are using a two-handed weapon.

No they do not. None of the Tzeentch spells include the wording "This is a Fire attack and causes double damage against flammable targets" as pure flaming spells do. This was confirmed via the High Elf Q&A for Dragon Armour which states that models with Dragon Armour are NOT immune to Tzeentch spells.

They are placed against the skirmishing model closest to the caster.

Yes. If there is an enemy in their way, they must declare a charge against them following the normal turn sequence.

The thing affected by the spell is the unit's voluntary movements: all voluntary movement, including those that result from a spell or incantation, even charge declarations, have to be made in the direction given by the delusions spell. This includes the voluntary direction that Spawn and Pump Wagons move in. However, the affected unit is not Immune to Psychology, and all compulsory movement still obeys its own rules (compulsory charges, failed terror tests, etc.). The unit can still flee a charge, but will still be affected by the spell as soon as it regains its freedom of movement.

Yes.

No.

No.

In Warhammer Chronicles 2004.

The rule say that you treat the model as having a mundane hand weapon, so all other effects not dependant on the weapons are still there.

Yes, as they are still Warriors of Chaos.

In Archaon's Horde, the 0-1 restriction is removed. They still take up two Rare slots, however.

War machines cannot move and shoot. However, when the Hellcannon Rampages, it IS allowed to Spew Ichor, as noted in the special rules for the Hellcannon.

No.

No, only models that are explained as working as wizards - so Liche Priests will be affected, but Warrior Priests and Tomb Kings will not.

The Hellcannon is a war machine. However, for such an expensive model that can continue to cause damage after its crew has been destroyed (albeit sometimes to its own side), we decided that Victory Points should be awarded in a slightly different way than normal. If all the crewmen are destroyed, the enemy gets half the Victory Points for the unit. If the Hellcannon itself is destroyed, then the enemy gets the full Victory Points for the unit, even if the crewmen are still alive.

No!

The Hellcannon rules specify that it fires in exactly the same manner as a stone thrower with the only exceptions listed related to special affects of the hit. The stone thrower rules in the main rulebook specify that they do not need to see their specific target, but they MUST see that there are enemy in the direction they are firing. This is confirmed in the 2002 Annual War Machines article. Therefore, if the line of sight of the crew to enemy units is completely blocked by a friendly unit, then the Hellcannon may not fire.

The Hellcannon IS ALLOWED to Spew Ichor if it is engaged in close combat.

They do count as a Core unit in a Daemonic Legions list, though not as a True Core unit.

Yes. These are the five spells that he uses in battle.

No.

In both cases (Yellow Fire and the Blasted Standard), treat them in the same way as Diabolic Splendour.

Yellow Fire of Transformation has been rewritten for the Daemonic Legions as a way to cast Diabolic Splendour as a spell as noted in the Q&A (printed in White Dwarf) above. Diabolic Splendour only affects the Daemonic character to whom the gift has been given (Storm of Chaos page 27). Hence Yellow Fire, when successfully cast, will only affect the Daemonic caster. Also note that the effect of multiples of the same gift is not cumulative (Storm of Chaos page 27). Since Yellow Fire is effectively Diabolic Splendour as a spell, if the Daemonic character has Diabolic Splendour gift already, casting Yellow Fire will not increase his ward save past 4+. This also means that the Blasted Standard, when carried by a Daemonic Herald, will only affect the Herald and will have no effect on the unit he is attached to. Note that the Unholy Icon which gives the unit carrying it a 4+ ward save is not the Blasted Standard and rules for the Unholy Icon do not affect the way that the Blasted Standard works.

Yes.

The effects are not cumulative. Thus, a Herald with the Mark of Khorne and the Armour of Khorne will have a 4+ armour save.

Mounted Daemonettes, Changebringers, Plagueriders, Pleasureseekers, and Bloodcrushers are all cavalry and thus gain +1 to their Armour Save. Note that this is already included in the Bloodcrushers" 5+ Armour save.

No. Dogs of War / Regiments of Renown are not listed as an option in the Daemonic Legions army list. In addition, note that in the standard Hordes of Chaos book an army led by a Daemon may not hire Dogs of War (Regiments of Renown) units either.
