For strong psyker abilities and good invulnerable saves, go with Tzeentch. For durability go with Nurgle. If you want speed, go with Slaanesh and if you want better close combat abilities, go with Khorne. Each has it's pluses and minuses. A Tzeentch Terminator Sorcerer with the Sigil of Corruption has a 2+ armour save and 3+ invulnerable. A Nurgle Sorcerer on a bike would have a toughness of 6. A Slaanesh Sorcerer has a better initiative and is best used in conjunction with Noise Marines. The Slaanesh Psyker powers really buff up sonic weapons depending on the power. A Chaos Khorne Lord on a Juggernaut with proper wargear is one of the best valued hard hitting units in the game.hey, basically i need help, i have the Chaos army from Dark vengence and a chaos terminator sorceror and i dont know which god to pick, i believe khorne is out as he dont do the sorcerer thing but as i'm new im open to your thoughts.
