Glamour of Slaanesh is very poorly handled.First of all it is not described anyway as to what it does in any formal sense.
Slaanesh Titans state that they have Glamour and a -1 to be Hit and a 4+ Psy save because of it.
Altar of Slaanesh list Glamour on the stats table (pg 44) but not in its description on pg 13. Lists it on Pg 6 as having Hard to hit because it is a demon engine of Slaanesh.
Slaanesh Knights are the opposite - List Glamour in their description on pg 13 ( but only mentions it as giving Hard to Hit- the 4+ Psy save is mentioned on a sperate line before it mentions Glamour) but does not list it as Glamour on Stats table but lists Hard to hit and the psychic save as seperate abilities.
So what exactly does Glamour do?
This then needs to be listed under the Slaanesh Entry and then Glamour listed as the ability in both description and on Stats table.
Atm very confusing as to what exactly it does and can't tell from stats table and /or description who exactly has it.
Black Legion
The Obliterators are not listed in the description as being their special unit (pg 17)
Dreadclaw Assault Shuttle
Assault spelt wrong on pg 22
Daemon Princes
adding "That didn't hurt" to their abilities on pg 5
Sample Army lists pg 7 Change "Choad" to "Chaos" in Black legion list
Change "Thunderhawk" for "Dreadclaw assault shuttle" in same list.
Chaos Marine Veterans
Points cost has to be wrong. Same cost as Normal chaos marines but has 1 better morale and the infiltrate special ability.NightlordsFlavour text says they are "masters if stealth, able to infiltrate a position quickly and silently" - they do not have any extra access to infiltrating units - they get cheap Landspeeders and cheap fear causing assault marines.
The rest of the flavour text would support the additional fear option.
Should they have infiltrating units or perhaps more fear related effects?
These guys also get a +2vp bonus for wiping out enemy units with no drawback?

?

?

To put this in perspective Tyranids get awarded extra VPS for a unit for wiping them out equal to the VPs for breaking them (so effectively double) but get no VPs for objectives.
The Iron Hands marine army gets +1 VPs for wiping out enemy units but it says "To balance this out, some of the Iron Hands units give 150% of normal Victory Points to the enemy."
Nightlords need a drawback to balance their free VPs either extra VPs in return or an in game factor that may limit thier tactics on occasions (like "Nightlords units must charge broken units within their charge range" or whatever else we can come up with
Raptor MarinesWay to expensive at 250pts for 5
Assault marines are 250 for 6 with 3 rhinos and a 5+ armour save instead of a 6+ for the raptors
Raptors should be 200 pts at the most - may be slightly under at 150 but seem slightly too high still at 200
Warlord Titan Special card needs adding to standard chaos listSlannesh Magi should be HQ unitsPlague Marines
Blank Stat line - should it be Chaos Marine or Tac Marine based Stats with the improved armour save?This applies to a lot of the non imperial army lists but how you buy units for codex armies needs to be better explained.As I have posted in another thread the rules for buying units from separate Army lists are described quite clearly in the main rulebook.
With a literal reading of that it makes chaos codex armies in particular particular limited in their choices of support cards for codex companies.
IE Under a Blood thirster Demon I could only take Khorne related support cards (Engines, lesser demons) but not beastmen, Trolls, Chaos marines or similar.
Speaking to a couple of people they were of the understanding that codex armies could take support cards from the standard list under codex list company cards. Is this the case?
Think this is it for the moment.
P.S All chaos units are too expensive

or I could be a touch biased
