Si deals Cryo DMG and applies Artful Intent, Immobilization, and Cryo Infliction (or Heat Infliction if a Heat element operator is in Team Position 01) on the target. After a target with Artful Intent takes DMG, part of the DMG taken is recorded. When the duration of Artful Intent ends, it bursts and deals Fixed DMG equal to the DMG recorded. After casting the skill, Si's battle skill is temporarily changed to Initial Stroke.
Initial Stroke: Costs 15 SP. Si pulls an Inksoul from a target with Artful Intent. All DMG dealt and effects applied to the Inksoul will also be dealt to its host (the said target). The Inksoul lasts as long as the remaining duration of Artful Intent. After casting the skill, Si's battle skill is temporarily changed to Final Stroke.
Final Stroke: Costs no SP. Makes the Inksoul disappear early. When disappearing, the Inksoul will move to its host and trigger a burst like the ending burst of Artful Intent.
When dealing DMG or applying effects to both the Inksoul and the host, only 1 instance of the DMG or effect is dealt/applied. If the host is defeated during the Inksoul's duration, it will link to another enemy in combat and apply Artful Intent to it. This does not reset the duration of Artful Intent. If a target with Artful Intent is defeated without having its Inksoul drawn out of it, the defeated target will drop an Inksoul at its location.
