Glad you mentioned it and since no one is here to back you up, heres the Bloodstone quote from Slaves to Darkness:
Bloodstones are dark, red-veined rocks, about the size of a clenched fist, and slightly warm to the touch. They are given only to the most favoured of Khorne's Chaos Champions and allow their owner to call upon the aid of Khorne's daemonic minions. Each Bloodstone may only be used once as the Stone is destroyed by the summoning.
During any magic phase in which the Champion is in b2b contact with a Khornate Chaos Altar he may call upon the Blood God for daemonic assistance, crushing the Bloodstone above the Altar and releasing the daemonic blood it contains.
It goes on the say the bonuses one receives for causing wounds, killing wizards, or Slaaneshi followers. A roll on the chart determines which and how many daemons are summoned & if you control them or not & if the champion is drained of his blood, dead by turning into a drained shell. Any followers of other Chaos Gods die in the same manner if they attempt to use a Bloodstone.
So. I'm a firm believer that once GW creates cannon and then moves on; it stands until reputed in the future. Its this belief that allows me to walk proudly into the LA Battle Bunker with my buddy's Slayer Dwarf Army from the ol' SoC lists. Bloodstones seem like a cool modeling aspect to a Wargor as well (maybe even converted from
The only question now is: Are stable Elementals on the same level as Daemons? in terms of summoning/controlling/plane of existance/etc. And is there only one of each Elemental or can multiple exist, say in the same army? I know there must be some text out there, possibly talking about those from Araby?
