Thing from the Stars

"A shard of alien malignity!"

- The Ancestor

The Thing from the Stars is a large Eldritch miniboss from The Color of Madness DLC that can be found in whatever region it is patrolling for the week (this is visible on the map when embarking). It has a 50% chance to spawn in any of that region's dungeons (including bosses), and will appear as a fight in any hallway. It is a very powerful enemy, capable of inflicting massive stress damage, blight, and diseases all within a few rounds. As the Thing is attacked, its combat ability increases, granting incredible resistance to direct damage and even more offensive power.

Behavior
The Thing from the Stars has 2 actions per round, and an automatic action at the start of each round (but not when the battle starts) that triggers Return to the Stars, a skill that hits all party members with Stress damage. This attack also spawns a Crystalline Aberration and deals a small amount of damage to the Thing. This attack does not trigger bleed/blight damage on the Thing, but all other attacks do.

After using Return to the Stars at the start of the second round, the Thing receives a permanent buff for +80% PROT, +6 SPD, +40% DMG, and +13% CRIT when below 45% HP.

It can open the battle with any move, but Paralysing Shard, Weakening Shard, and Transfixing Shard all have a 1-turn cooldown, meaning it will never use them twice in one round.

The Thing has an unforgiving set of targeting biases, prioritizing heroes with the lowest stun resistance with Paralysing Shard and stressed heroes with Phase Gnaw.

Strategies
All of the Thing's attacks inflict significant stress damage, and with 3 actions per round, you are in far greater danger from Afflictions and accumulated stress than HP loss in this fight, especially in the first phase before its DMG buff is applied. In addition to causing massive stress, the Thing will regularly deliver powerful debuffs, stuns, and blight. Weakening Shard reduces all relevant resistances and Transfixing Shard reduces DMG and SPD.

The Thing has high accuracy on many of its attacks, with Return from the Stars being effectively undodgeable. Dodge-based strategies, such as utilizing an Antiquarian's Invigorating Vapours, or the Houndmaster's Guard Dog are likely to be ineffective. Similarly, Phase Gnaw, while it does much less damage than Vorpal Strike is actually armor piercing, rendering any PROT buffs from skills like the Leper's Withstand useless.

For the first phase, focus primarily on mitigating and preparing for high stress, and bringing the Thing down to its 45% HP threshold. Its damage in this phase isn't much to be worried about aside from the possibility of a crit from Vorpal Strike.

Arguably the biggest problem of a battle with the Thing is the possibility of contracting Sky Taint, a disease that grants +20% Stress and -20% Blight and Bleed Resist that can be obtained from the attack Phase Gnaw. If a hero gets Sky Taint early, it will dramatically lower their defensive ability as they build up even greater levels of stress and deal with a large vulnerability to the powerful blight from Phase Gnaw.

For the Thing's second phase, both blight and bleed damage are highly effective, due to its low resistances—you'll usually trigger all your damage within 1-2 rounds at most, though ensure you have enough chance to bypass resistances on higher levels. Note, however, that the Thing uses Return to the Stars at the start of each round, which will clear all damage over time effects. In order to get the most out of bleeds and blights the characters will have to have enough speed (and luck) to act before both of the Thing's turns; no damage will be applied from the damage-over-time effects if they are applied after the Thing's second action, as Return to the Stars does not trigger them.

Outside of blight/bleed damage, the Grave Robber's Pick to the Face or the Shieldbreaker's Pierce will both completely ignore the Thing's 80% PROT, allowing those heroes to deal full damage. Consider bringing them along if the Thing is patrolling a particular region.

The Thing will summon a Crystalline Aberration every turn with Return to the Stars, so you'll need to deal with it in good time to prevent it from exploding—it has very low HP and no dodge, so using a dedicated hero, preferably with AoE damage, is recommended to keep it destroyed. Aberrations have no resistance to blight, but you only get one turn to kill them, so ensure you can stack enough damage to finish them if using a blight-based strategy; the Plague Doctor's Noxious Blast, the highest-damage blight in the game, is the best option, as it will kill the Aberration even on Champion level.

It is worth mentioning that upon creation of the Crystalline Aberration, the Thing will take a small amount of damage and have a chance at causing party-wide stress. It is possible to stall out the fight until the Thing kills itself by using Return to the Stars, but be wary, as stalling for too long may result in multiple heroes receiving Sky Taint and massive stress for your party.

Debuffs, particularly PROT debuffs, are not very effective, as they wear off too quickly for prolonged damage-dealing using them.

It is also worth noting that if the Thing is stunned after using all of its actions for the turn, it will not use Return to the Stars at the beginning of the next round, allowing bleed and blight to stay for another round. However, as the Thing has high base Stun Resist, this is difficult to do multiple times in a row.

Loot
After defeating the Thing from the Stars, you will receive 15, 20, or 25 Comet Shards alongside a randomized amount of gold. There is additionally a chance the Thing will drop one of its unique Trinkets. The exact chance is 1/7 (~14%) on Veteran missions, and 1/5 (20%) on Champion. There is an equal chance the Thing will drop a Memory on death instead, which is otherwise only obtainable by defeating The Sleeper. Neither will drop on Apprentice missions, but you will still get shards.

Prismatic Quirks
Heroes who survive the battle with the Thing from the Stars may receive one of several new quirks after the mission is over. These quirks are unique; they can only be on one hero in your whole roster. Only one hero will receive a quirk on a given mission, and gaining more requires defeating the Thing once again. They are automatically locked, and the Sanitarium will only offer the option to remove them. Removing Prismatic quirks allows them to be obtained again the next time the Thing is defeated.

The following list is of the quirks in the order they can be obtained, and their effects:

Trivia

 * You can easily spot the Thing on the map with Scouting if you see two battles in a row in a hallway.
 * The Thing from the Stars is likely greatly inspired by John Carpenter's "The Thing" (1982) in that the Thing comes from outer space and it also assimilates biological aspects and traits from any lifeforms it encounters.
 * It may also be a reference to H.P. Lovecraft's "The Colour Out of Space." It can be seen to have incorporated the body parts of at least two small humans and a large farm animal, the same as were found in the farmstead well at the end of Lovecraft's story.
