Deploy-timed skills run the normal duration lifecycle: one charge on deployment, a duration bar, a real end, again on the next deployment (#109)

宴 S2, 斯卡蒂 S2, 野鬃 S1, 砾 S1 / S2, 伊内丝 S3, 缄默德克萨斯 S1–S3 and 耀骑士临光 S2 used a separate timed buff while the skill stayed active; equipment and bond effects that read the skill state now see it end. 伊内丝's first sentry placement starts no skill. Contributed by @Sukvii.
