The S2 / S3 kill tracker kept only the last target of his attack, so the
true damage carried by that attack (卡西米尔 bond, 天马之枪) overwrote it and
a kill landed by that damage was not counted: S2 lost its "trait not reset"
in the 卡西米尔 lineup or with the 天马 set, and S3 never lowered the trait
bonus with the 天马 set. Track every enemy the current attack (or the mark
it set off) hit, cleared after the attack; reflect kills and marks set off
by other operators stay excluded (PRTS 备注).
