Vault 87's Evolutionary Experimentation Program exposed subjects to an airborne version of FEV. Rapid physical enhancements accompanied sharp mental regression, and the oldest mutants would become almost feral.

Im Rahmen des Programms für evolutionäre Experimente in Vault 87 wurden Versuchspersonen einer über die Atemwege übertragenen Version des FEV ausgesetzt. Rasche körperliche Verbesserungen gingen mit einer starken geistigen Regression einher, und die ältesten Mutanten wurden fast zu Tieren.

Mutierende Biomasse

Kreaturen, die du kontrollierst, haben Basis-Stärke und -Widerstandskraft X/X bis zum Ende des Zuges.

El Programa de experimentación evolutiva del Refugio 87 expuso a los sujetos a una versión del VEF que se transmitía por el aire. Las rápidas mejoras físicas vinieron acompañadas por una regresión mental aguda. Los mutantes más ancianos se volvieron unos salvajes.

Mutación de la biomasa

Las criaturas que controlas tienen una fuerza y resistencia base de X/X hasta el final del turno.

Le programme d'expérience évolutive de l'Abri 87 exposa les sujets à une version aérosol du VEC. On constata une évolution physique fulgurante chez les sujets, accompagnée d'une régression mentale sévère, et les plus vieux mutants devinrent presque sauvages.

Mutation de biomasse

Les créatures que vous contrôlez ont une force et une endurance de base de X/X jusqu'à la fin du tour.

Il programma sperimentale sull'evoluzione del Vault 87 espose i soggetti a una versione a trasmissione aerea del VEF. Rapidi potenziamenti a livello fisico accompagnarono una spiccata regressione delle capacità cognitive, trasformando i mutanti più anziani in creature feroci.

Mutazione della Biomassa

Le creature che controlli hanno forza e costituzione base X/X fino alla fine del turno.

Vault 87の進化実験プログラムでは、被検体は空気感染するように改変された強制進化ウイルスにさらされた。筋肉の急速な増大と精神の著しい衰弱により、時間が経ったミュータントはほとんど野生化する。

生体材料の突然変異

ターン終了時まで、あなたがコントロールしているすべてのクリーチャーの基本のパワーとタフネスはＸ/Ｘになる。

87号避难所的进化实验计划，是让实验对象接触能通过空气传播的FEV病毒。结果他们体能快速增强，心智极度萎缩，就连最年长的变种人也变得无比凶残。

巨量突变

由你操控的生物之基础力量与防御力为X/X直到回合结束。

Biomass Mutation

Creatures you control have base power and toughness X/X until end of turn.

Fallout

Biomass Mutation overwrites any effects that set the power and/or toughness of a creature you control to a specific value. Effects that modify power and/or toughness but don't set them to a specific value (like the one created by Giant Growth), power/toughness changes from counters, and effects that switch a creature's power and toughness will continue to apply. For example, say you control a 1/1 creature that's getting +4/+2 from an Aura, has a +1/+1 counter on it, and is affected by an effect that switches its power and toughness. This creature is 4/6. If you cast Biomass Mutation with X equal to 4, the creature would become 7/9 (4/4, +4/+2 from the Aura, +1/+1 from the counter, then switch power and toughness).

Choosing 0 as the value for X will likely cause creatures you control to become 0/0 and be put into the graveyard.
