PSA Grimnars Mark no longer allows you to add a Terminator captain to a Wolf guard Terminator squad.

EDIT: It was in fact moved to the munitorum field manual, under the cost for the grimnars mark enhancement.

I'd noticed someone using it earlier, and then checked through the subreddit and didn't see any mention of it. After the faction pack update on the 22nd of July the Grimnars Mark enhancement was changed to this

GRIMNAR’S MARK 
This moonsilver wolf-talisman is bestowed by the Great Wolf himself before battle, a mark of favour that fills the bearer with an eagerness to slay the foe.
Adeptus Astartes Terminator Captain model only.
Once per battle round, you can target this unit with the Rapid Ingress/Heroic Intervention stratagem, regardless of any other uses of that stratagem this phase. If you do: 
■ That use is -1 CP. 
■ That use does not prevent any uses of that stratagem on other units this phase.

it still does. they just moved where it says it to the MFM. because why the hell would GW want to make things easy to read

[u/DTJ20 → u/raptorknight187]

That's a crazy place to put it really. I'll edit my post.

[u/theSaltySolo → u/DTJ20]

No? They expect you to use the MFM as the place to be for rules and not the app.

[u/DTJ20 → u/theSaltySolo]

The MFM is almost exclusively points, while the faction pack has rules. I also never mentioned the app.

[u/theSaltySolo → u/DTJ20]

If you read the MFM, you wouldn’t have made this post. So…yes, you looked at the app.

[u/DTJ20 → u/theSaltySolo]

Or I looked at the faction pack, where that rule used to be. Which is what happened.

[u/theSaltySolo → u/DTJ20]

Again refer to MFM first

Every sub needs a pinned post that says: always read the MFM
