Don’t miss all the daily updates, including new Warhammer 40k rules detachments for Grotmas Calendar 2025 that started with Capt. Titus and the 500 worlds.
The snow is falling, the grots are rowdy, and Da Red Gobbo has raided Santa’s workshop again. Yup, the Warhammer Grotmas Calendar is back for 2025, and we even got new 40k rules!
And yes, Captain Titus kicked the whole thing off, but despite some of the early hype, things sort of crawled along until they started dropping new Warhammer 40k rules updates.
Let’s break down the new Grotmas Calendar 2025 day by day.
Grotmas Calendar 2025 Overview
Updated on December 8th, 2025, by Rob Baer with the latest Grotmas Calendar drop from GW.
GW kicked off the Grotmas calendar 2025 by promising a proper party for both Warhammer 40k and Age of Sigmar players. They teased fresh daily drops like rules, painting guides, early fiction, and whatever chaos Da Red Gobbo refuses to leak.
Grotmas Calendar 2025 Reality Check
Then reality showed up, and the Grotmas Calendar did not exactly stick the landing. Folks expected the old Advent energy where real rules dropped, and everyone mashed refresh like it was Hobby Christmas morning.
Instead, we got AI art slop and posts that felt like standard Warhammer Community leftovers dressed in green.
Warhammer Grotmas Calendar Course Correction
Things finally turned around on Day 5 with actual Warhammer 40k updates, and the Warhammer Grotmas calendar finally woke up. Once GW stopped phoning it in, the event picked up some speed. Now the run toward Grotmas Day at least feels worth watching.
Grotmas Calendar 40k Rules Rumors
Looks like the rumor mill is cooking again, and this batch actually has some teeth. A couple of these detachments are already confirmed, and the rest line up a little too neatly with recent design trends to ignore.
From Emperor’s Children strutting in with their Court of the Phoenician to Space Wolves chasing fresh glory with a new saga, the spread hints at big shake-ups across Marines, Chaos, Guard, and Aeldari.
2025 Grotmas Calendar Updates By Day
December 8th: Aeldari/Harlequins Detachment
The Serpent’s Brood gives Harlequins a wild mix of extra hits, redeploy tricks, and movement shenanigans that make your army feel uncatchable. Your bikes, boats, and Troupes all hit harder while dancing in and out of danger, backed up by strats that let you advance, charge, bounce away, or even leave the table entirely. It is the strongest the clowns have looked in 10th.
December 7th: Blood Angels Detachment
If you are running a pile of Death Company and want a detachment that rewards you for getting wild on the tabletop, this one is your flavor. The whole theme leans into the Red Thirst and Black Rage, so your units hit harder, crack more armor, and even get juicier bonuses when they are battle shocked.
December 6th: Chaos Space Marines Detachment
The new Chaos Space Marine Nightmare Hunt Detachment has enhancements that stack more ways to trigger Battle shock, slip units back into reserve, or sneak jump leaders into Warp Talons for extra mobility and early board reach. Stratagems pile on more tests and give strong rewards against shaken units, from better hits and wounds to Advance and Charge or Fall Back tricks that set up nasty follow-up plays.
December 5th: Astra Miliatrum Detachement
If you like your Guard tough enough to chew gravel and still bark Orders, the new Grizzled Veterans Detachment is your new toy. Re-roll 1s To Hit into anything on the board means your guns stay hot even when the dice try to betray you, and the boosted version against targets on objectives lets you re-roll 1s To Hit and Wound.
December 4th: A Bone-Chilling Nighthaunt Story
If you want a spooky little stocking stuffer, today’s Grotmas Calendar drops a Nighthaunt story that hits decently hard.
December 3rd: Space Marine Painting Guides
From the Dark Angels’ “mysterious on purpose” armor to the Salamanders’ scorched green vibe, there is a guide to make every Legion pop on the tabletop. If you want your Loyalists looking sharp enough to make Horus squint, this little rundown is worth a peek.
December 2nd: New Helsmiths Goodies
The Grotmas Calendar dropped a fresh batch of Helsmiths of Hashut content, and yes, the whole thing reads like an AI got locked in a forge and told to “sound grumpy and metal.” The big takeaway is simple: the faction finally gets its Scourge of Ghyran rules,
December 1st: The Emperor Protects… and So Does Captain Titus
Day one of the Grotmas calendar dropped a banger of a Warhammer 40k short story. General Strayk and his Guardsmen are barely holding it together as Tyranids tear their world apart, until a single name cuts through the static: Captain Titus. Yep, that Ultramarine.
The Red Gobbo Might Be Wearing AI Art, and It Is Hilarious
Let’s talk about those goggles in the Grotmas Calendar preview. Or, more accurately, the two sets of goggles on the Red Gobbo’s hat in GW’s promo.
Either this grot is rolling into Grotmas with a double dose of night vision, or someone hit “Generate Again” on an AI art prompt and didn’t notice the extra eyeballs.
Very festive, but maybe also very cursed. Very, please don’t tell the Inquisition, especially since no previous miniatures or art sport a double set.
Final Thoughts on Grotmas Calendar 2025
The Grotmas Calendar 2025 edition is chaotic, festive, and probably held together with hot glue and grot magic. Captain Titus showing up on day one is a strong hook for Warhammer 40k fans, and after that, things are sure to keep getting spicy.
Just keep an eye on the art, because if the Red Gobbo sprouts a third set of goggles, we may need to call the Ordo Xenos.
Until then, let’s enjoy the ride. Grotmas has begun.

Disgusting to think that shilling for a company like that is a thing. That is a VERY disappointing grotmass so far and it does not hold to last year’s at all.
Oh yeah its a big dissappointment like most things GW did this year, yet they are a $6B company now. Not sure how time or money works anymore honestly lol.
