Additional information
  • Avalanche Breaker will prematurely end if Rosa is disabled or affected by Necrosis Damage while it is active, or all targets leave the map.
  • If the target moves out of her range during the skill e.g. because they are immune to Bind, she will keep attacking them for the duration of the skill.

Description
Chernobog.
Natalya curled up her legs to cover them with the plastic sheet. She already knew how to get a little warmth while sleeping alone, and how to avoid being discovered by other refugees or the Reunion Movement. It wasn't actually time to sleep, but she was too tired. In hopes of getting Lada a little soup with flavor for her fever, Sonya grabbed half a leather belt off another group of refugees. And, of course, they didn't let her go easy. They chased Sonya all the way back to their hiding place. The commotion woke the already weak and drowsy Natalya. She used the huge weapon she had been carrying on her back for the first time.
A few days ago, they dragged it out of a burnt-out ruin, and after inspecting the remaining parts, despair yet again cast its shadow on their hearts–it was practically unusable. Natalya describes it as a former siege weapon, now abandoned. Several eyes looked it over only to fall into silence.
But Natalya still found a few almost-usable cloth straps and fixed the huge device to her shoulder. Anna and Sonya said nothing, they just clutched their own handy weapons tightly and walked on in silence. Natalya followed.
The massive weapon now rested across the bottom of Lada's neck, covered with a layer of found fabric, making it just a little bit softer. It didn't actually fire anything that could cause any real damage in the recent scuffle, but Natalya stood in front of a few already-broken refugees, and snapped off a component of unknown function–the weapon worked strangely, a mixture of thick black smoke and flames gushed out, igniting the debris next to it. The fire drove off the refugees who were pursuing Sonya, meaning they lost their own hiding place.
Several hands tugged at the plastic sheet in the corner. Anna coughed weakly, trying to muffle the sound in her throat. Sonya stared into space with her eyes wide open, not allowing herself to sleep. The flickering flames in the distance reflected on their faces. The feverish Lada suddenly clenched her fists and woke up from her sleep, muttering and grabbing the small pot next to her, preparing to rush out.
Anna skillfully placed her hand over Lada's forehead, and Sonya pressed down the corner of the plastic sheet to prevent the wind from coming in. Through the gap in the sheet, they saw the dark night sky, glittering stars, and Natalya, still cowering alone nearby. Lada murmured and reached out to her, and after grabbing her equally pale hand, she quieted down and slowly fell back asleep.
The next day, Natalya felt an unfamiliar warmth beside her. When she woke up, she saw a small, yellow, dirty star-shaped plush toy hanging off her weapon, swaying back and forth. Lada wrinkled her nose and laughed.

Rhodes Island.
"Please wait a moment, Sonya. I'm not ready yet."
"Ugh, you suck, Natalya."
"Listen, you're a logistics operator, and you're the one who applied for a replacement weapon. How did I end up being the one pushing you through the process?"
"Because I suddenly realized that I've gotten used to it."
"You've never even fired the thing. The last time you tried, the pile of scrap almost exploded on you."
"I know how maximally utilize its functions."
"You told us it was a military siege weapon."
"Well, I like its color."
"Ugh, are you screwing with me? Do you wanna use it or not?"
The white-haired girl laughed. She fiddled with a dirty, tattered, star-shaped plush toy behind her back and remembered the night when she huddled with her companions for warmth.
"I've changed my mind. I don't want to replace it. To me, Sonya, it's more than just a weapon."

Description
娜塔莉娅缓慢而仔细地收拾着行囊。
距离正式离舰还有一小段时间。她的东西不多，衣物、书籍、信件。武器与保养套装早已另外打包，会先行送上载具。女孩检视着已经在睡梦中盘点过无数遍的行李，突然伸出手去，从针线包中掏出一枚扁扁的圆片。
“这是？”
疑惑很快就变成了恍然大悟。一枚毛毡徽章，刺着自治团的徽记。这还能是什么呢？


“这不是索尼娅的徽章吗？”
早露打开真理的储物柜，想像往常一样从里面取出茶具，却发现了一旁多出来的小圆片。借着光线，她认出这是属于凛冬的那枚，也是她们试做的第一枚自治团徽章。
“哦，这个。她说自己可能会在战斗中把它弄丢或弄坏，就寄放在我这里了。”
“什么呀，还真像索尼娅会做的事。”
“嗯？”
“把心留在故土的战士，因为不再害怕，所以在战场上所向披靡。这和索尼娅把徽章留在朋友的身边，是一个道理吧？”
“我倒觉得她没想这么多，也许只是怕麻烦。”
早露笑了起来。征得真理同意，她把徽章拿出来端详，发现表面的确已经开始起球，背面也明显弯折了。受到托付的人做过一些修复的努力，但似乎都以失败告终。
“安娜，把索尼娅的徽章交给我来修复吧。”
被叫到名字的女孩只是点了点头。茶泡好了，聚会的人却还没到齐。真理端起茶壶，把滚烫的茶汤均分到五个人的杯盏之中。


毛毡制品难以恢复如初，直接重做一个却也有违“修复”的承诺。更换材质呢？那就必须给所有人都重做，是需要大家一起讨论的问题。
顺着往下一想，她很快就知道了为什么这枚受损的徽章会被搁置至今。而在这临行前的时间里，似乎也没有空余去完整实施任何一个方案，现在能做的是——


“索尼娅，你在吗？”
娜塔莉娅推门进去，看到敞开的行李箱和丢了一地的衣物。房间的主人正在翻箱倒柜地找着什么，听到开门的声音也没有回头。
“你在找这个吗？”高个的女孩轻轻问。
索尼娅回过头去，看到来人手中的毛毡徽章，皱了皱眉，没有否认，也没有承认：“怎么在你那里？”
“这个嘛......我想再做一批自治团的徽章，这次不用毛毡，做得更坚固、更耐磨一些。冬将军觉得怎么样？”
“那就叫上大伙一起商量，你拿着我的做什么？”
“先问问你的意见。”
“我觉得毛毡的就挺好，至少轻便。要重做的话，我也没意见。不过——”
“什么？”
“既然要做，那就再多做几个吧。备用，或者万一有新人加入......
“总觉得回去之后，还会有很多事发生。”
