Infernal Tetrad

The Daemon Princes of an Infernal Tetrad have the following benefits depending on how many of them are on the battlefield at the same time (the bonuses are cumulative):

No. of Models	Benefit(s)
4 Models	+1 T
3 Models	+1 S
2 Models	Re-roll failed To Hit rolls of 1
1 Model	No benefit

If your Warlord is chosen from this Formation, all of the models in the Infernal Tetrad also have that model's Warlord Trait, even if you chose to roll on one of the Warlord Trait tables in this book and they have a different daemonic alignment to your Warlord.
