今天新发现的bug。亚砂2形态（狙击）会衍生一张回手的卡，在明光花瓶的最终战中，我对亚沙使用回手，不知道为什么，500血的清理者boss也被返回了我的手牌？（亚砂正常回我手里了）
明光效果给的亚砂，给了清理者一个雪球，场上还有3个伙伴是阿卡赛特、天音、克洛托
有截图，但不知道发哪儿（b的私信也是我发的，但当时手抖回车直接按下去了

This is a complex one.

The boss Asmodeus has Void Hearts, which must be healed to remove.

Asmodeus gives your team the status Berry, causing your team to deal healing instead of damage. When attacking, this can be seen on the character by their attack stat becoming negative.

The bomb status effect causes attacks that hit an enemy to deal plus 1 damage per stack.

When the boss Asmodeus is afflicted with Bomb, the additional bomb damage will bring the attack of Berry affected allies back to positive, making it deal normal damage again.

This makes Asmodeus largely invincible to builds using the bomb status, such as those using Colcher.
(though this is partly solved by Lucifer Cleansing the enemy team)

The same kind of effect also applies to Frost applied to allies with Berry, which applies -1 to attacks and causes the 'healing' of Berry allies to deal additional damage to void hearts.

Also, effects that give Temporary attack, such as using the character Asuna, will typically cause Asmodeus to lose no void hearts at all, no matter if the final attack is negative or not.

The enemy boss Data Cremator has the ability 'When hand destroyed apply self with it's attack effects'.

The Upgraded version of Asuna's soul card 'Sniping Readiness' has the effect 'Select and return an ally to hand'

Using Sniping Readiness will add Data Cremator to the player's hand.

This ruins the run, as the boss cannot be played from hand in order to kill it.

Edit: After restarting the game and loading the run, I was able to play the Data Cremator, on my side of the board. Currently attempting to kill it, 2 damage at a time.

Edit Edit: killing it on my side of the board was a victory!

The card 'Below The Moon' has the effect 'Apply: When kill gain Moon 1'.

The effect works perfectly, but the line 'When kill gain Moon 1' doesn't get added to the text of the targeted card.

When the enemy team is reduced to only having opened gear hearts, they die on activation.
When the boss enemy dies this way, further enemies do not proc, and don't die for the kill combo bonus.

Killing the Enemy boss 'The Beginning and End' with an attack card from hand (Scallion Sword) while Xi Lu is in her second from caused an exception:

This also occurs when killed by a companion that applies a status effect on hit.

The boss dies correctly if hit by an attack that does not apply a status effect.
