Welcome to Librarium Online!
I recently played against a Lizardman player who had the Mark of Tepok (adds one dispel dice mark) on two figthing characters.
I was wondering if this was allowed, similar to Marks of Chaos. Or if these marks are just like magic equipment and are one per army.
In the standard lizardman army list, Oldbloods are allowed 3 blessings, Scar-vets are allowed 2, skink priests and skink chiefs are allowed the blessing of Sotek and the Blessed Mark of the Old Ones. The Blessed Mark is only allowable one per army. Saurus troopers are allowed to have blessings, but one blessing makes them a special choice and two makes them rare.
So it is indeed possible that you fought two characters that had the same blessing.
Yes, a Blessed Spawning can be taken multiple times in the same army - in fact, there are armies in which almost every model bears the Blessed Spawning of a particular Old One (or Sotek).
The only exception is the Blessed Mark of the Old Ones. Only one of these Marks may be included in an army.
Also, Lizardman characters can take varying numbers of Blessed Spawnings: Skinks can take one, Scar-Veterans two and Olbloods a whopping 3! The Blessed Mark of the Old Ones counts against the Spawning cap, so if you give a Skink character the Blessed Mark, it may not have a Blessed Spawning. The cost Blessed Spawnings and the Blessed Mark DOES NOT come out of the character's/unit's magic item allowance.
Also, Saurus units move to Special if they have one Blessed Spawning, and to Rare if they have two Blessed Spawnings. Units cannot bear the Blessed Mark of the Old Ones.
If the player has a Sacred Host, EVERY character apart from a Slann and every Saurus Warrior/Skink Skirmisher unit has to have the patron's Blessed Spawning, and this single Spawning doesn't affect the unit's Core/Spec/Rare status. If a unit of Saurus in a Sacred Host has two Spawnings, it counts as a Special choice. The Spawnings in a Sacred Host aren't free: They have to be paid for and take the appropriate Spawning slot from the character/unit. In the Sacred Hosts of Huanchi and Tzunki, Skinks do not have to take the patron's Blessed Spawning.
There. Hope that helps ^^ (and sorry if it's a bit long)
