New battlescroll w/ points update is out. Notable changes:
1. Change to Coherency: single coherency is for units of up to six instead of five, double coherency for units of seven or more instead of six or more. This is a big buff for monstrous infantry units with unit size 3 and 1" reach, like Necropolis Stalkers, Crypt Horrors, and Crypt Flayers, as they can now more easily get all their attacks in even when reinforced to 6 models. Also obviously a boon to units with batch size 6, but I don't recall any such units in death factions off the top of my head. The coherency rule is especially important since...
2. Double Rank Attacking is Gone: where the galletian veteran season let battleline infantry fight in two ranks, and the galletian champion season provided a formation to let infantry units in general do so, neither the andtor ghb nor the battlescroll has such a rule. I was honestly expecting it to be worked into the battlescroll as an update to the core rules, but no. This is a BIG debuff to semi-elite melee units on 32mm bases with 1" reach, like Bladegheist Revenants and Dreadscythe Harridans. Thankfully most death factions have access to units with either reach (Grimghast Reapers) or small base sizes (grave guard, mortek guard, crypt ghouls), which can fight with all their models while maintaining double coherency even without a special fight-in-two-ranks rule.
3. Change to Look Out Sir: while double rank attacking didn't get folded into the core rules, the inability to target Galletian Veterans sort of did. Small Infantry heroes (No Mount, <10 wounds) cannot be targeted by missile weapons while they are within 3" of a friendly unit with 3 or more models unless they are within 12" of the firing unit. Companions do not count as mounts for this rule. So the protection wears off when the enemy gets close, but as long as you screen properly and don't shove them too far forward your support heroes shouldn't get sniped off the table in the first turn.
4. Changes to Soulblight Gravelords: units restored by endless legions on your opponents turn must be deployed more than 9" from enemy units. Units restored on your turn can still be deployed more than 3" from enemy units. Also zombies now need to be within 3" of the unit that killed them in order to explode. At first glance I find both of these changes to be reasonable, and I don't think they kill anything on their own - though there are points changes as well.
5. Points Changes: Nagash down 65 points to 900. Still at least 100 points overpriced imo, but some mad fools are sure to try him out at the new cost and maybe they'll show me wrong. For individual factions:
- Points decreases for a bunch of nighthaunt stuff, most notably -30 for Olynder, but oddly enough no changes for Bladegheists or Dreadscythes which both got a lot worse with the change to the seasonal rules.
- Few changes to FEC, though apparently some of their units are getting entirely new rules in the narrative campaign book.
- Lost of stuff up and down for Soulblight, some by a fair bit. Too much for me to have an overall take on at a glance.
- OBR absolutely decimated with points increases to everything that has been seeing use - Katakros, Arkhan, Boneshaper, Deathriders, Immortis Guard, and the shrieker. Not huge increases to any one thing, but the last OBR tournament army I saw would be hit with a colossal +170 points. Some decreases, including a hefty -30 to the harvester, but given its rule change even that might not be enough for it to see play, especially as Mortek Guard did not get a points decrease. Neither did the Crawlers. Morghasts are down 20 points, so maybe they'll see play, and you could probably put a list together around stalkers, but honestly I wouldn't be shocked if the army went from the top of the charts straight to the bottom based on these changes.
I'm not sure that I agree that the overall changes kill soulblight. Their book is very deep with a ton of builds and options, what lists work best might change, but I'll be surprised if they disappear completely. OBR might be out of contention until the next points update, or they might be able to make something work, but their current list is dead as a door nail, and that book is /not/ deep enough to easily shift gears. Can't really speak to FEC without seeing the new unit rules. Nighthaunt could probably put something together. Big hits to dreadscythes and bladegheists probably shift the subfaction preference towards emerald host and grieving legion. Particularly the host, with the curse putting enemy small casters on a timer.
We'll also have to consider the narrative campaign rules, which aren't out yet. FEC get a new hero and new rules for some of their units. Other Death armies get a new regiment of renown with a bunch of ghoul stuff, probably eating up a fair chunk of your points. Likely to be relevant for OBR in particular, as they're struggling pretty badly for points efficient bodies in faction, but without seeing the rules it's hard to say.
For those who struggle with lumineth, their shooting did get a pretty big nerf in that the subfaction that used to grant +1 shot at close range now grants +1 to hit & wound instead - still a big buff, but it doesn't help them score more natural 6s for mortal wounds.
