So, basically these guys are meant to be 1k Sons Terminators. I'm using a caveat similar to the special Terminators in Black Legion that you need to have a specific
HQ present to unlock 1 unit of them.
I've thought long and hard, and I think what they gain with Inferno Bolts and Fearless, they lose by not being able to access wargear upgrades, so the base cost of one of these Terminators will just be a Chaos Terminator + Mark of Tzeentch (Aura of Dark Glory is presented for fluff reasons only, and obviously doesn't stack with Terminator Armor invul). So question 1 is, do you think that's fair, overcosted, or undercosted?
Where I'm running into the most trouble is pointing up an Aspring Sorcerer instead of a Terminator Champion. I'm a bit at a loss here. If you got ideas, let me know!
Scourged Terminators
Counts as Chaos Terminators, except as noted below:
May not take Veterans of the Long War rule.
Gain Aura of Dark Glory and Inferno Bolts wargear.
Gain Slow and Purposeful and Fearless special rules.
Scourged Terminators must take the Mark of Tzeentch.
Swap Terminator Champion with Thousand Son Aspiring Sorcerer, except in Terminator Armor instead of Power Armor, and with a Combi-Bolter instead of a Boltgun.
The Scourged Terminator Aspiring Sorcerer has the Zealot special rule.
Scourged Terminators may not take wargear upgrades (the Scourged Terminator Aspiring Champion may take a Gift of Mutation and an Icon of Flame).
