got a few questions, can i attach a chaos lord to a chaos marine squad or termie squad and be able to attach/detach from that squad mid game? also if he's with the termie squad can he deepstrike with them? and will the attached squad have to be dedicated to the same god as the lord?
-thanks in advance
Sorry it took a while to get to this. There's a couple threads taking everyone;s focus right now ;-)
Yes, you can attach and detach an Independent Character from any squad, at any point during your Movement Phase. (See p50 'Characters' in the main rulebook)
If your Lord has Terminator Armour, then he may deepstrike as your Terminators do. And, assuming they;re both available on the same turn, he can deploy as part of their unit.
However, and this is important, you must roll for their availability separately. When you choose to deploy with Deep Strike, then you place the unit in Reserve. Every turn after the first you make a roll (based on the table on p85) to see if the unit is available. If it becomes available, it *must* be deployed.
So there is a chance that your Lord could come up before your Terminators, or vice versa.
For that reason, I prefer not to put ICs in deep-striking terminator squads.
And no, you do not have to have the same mark.
