Dealing with screamer-star

So, I have played a few games against demons with a full unit of screamers and a bunch of other gribblies who are tricked out to have a 2+ inv save with a re-roll. As they have two wounds each, they're just impossible to shoot off the table. Anyway, someone pointed out a strategy that DE could use against this unit. I wanted to know if anyone had any experience with this.

Add torment grenade launchers on your vehicles. Give your haemonculi a Crucible of Malediction. When the screamers get close move up and use the torment grenade launcher to reduce their leadership to six and then spring the crucible. If they fail the leadership test then they're removed from play with no saves of any kind... You could even deep strike your vehicle into their ranks and spring the trap... Any thoughts? RB

The screamer star can only kill one unit a turn, and takes up 700-800 points of his army. A 2+ re-roll-able is the same as being invincible. Ignore it and focus on killing the rest of his army, run your troops outside of their transports for more saturation, and go to ground liberally. Wait until he either fails his grimoire, meaning they only have a 6++ (4+ cover if they turbo), or wait for a -1 to saves on the warpstorm table, or for him to fail casting forewarning. Also the herald with the grimoire doesn't benefit from the boost to his invulnerable save, meaning he only has a 5++ so it's possible to snipe him if the opportunity arises (precision shot/strike, wound allocation, barrage).

you handle it as the same way as people did harliestar and paliestar. The difference is that while theirs were constant 2+ re-rollables, screamerstar is only if they get the grimore off. Just google or search up tactics on how to deal with those two older variations of this same trick, and you will see some decent ideas.

If they're running Kairos The Flying Dude, kill him ASAP. There is only ONE grimoire. Venoms and kabalites are good at this, he's only 4++ T5 or 6 (like we care about T) flying dude. (He isn't the greatest threat here, but his presence alone gives Daemon player re-rolls... and guess what roll would he re-roll).

Wait until screamers fail their grimoire role and viola, they welcome lances and splinterfire with brand new 6+ invulnerable save. Usually this happens at turn3. Kite them and feed small units until that moment.

Screamer star can easily kill three units in one go if you are bunched together. So keep your distance and KNOW the multible assault rules.

Fatey will use its reroll for grounding test on your turn, but two guided (precienced) Venoms kill it from the air. Usually though Kairos is not in the screamer lists.

Usually I'd advocate killing the grimore first.
Usually it's on a DP and is well worth the killing in any case - and we kill DPs *really well* compared to most races, because, hey, even our mooks are a solid threat.

Then you can shoot up the Screamers.

The strategy you described will certainly cause them headaches...but suffers insomuch as it's not all that good against most armies, so I tend to suggest using alternate means. Most armies if given a single opposing unit to deal with can come up with a gnarly strategy to put a hut on it...but that strategy is rarely all that useful versus other opposing units, and is thus a weak strategy even if it works very well on a specific target.
