When Bursting a fragile backline target after transforming into Shadow Assassin

1. EEngage→
2. RUntargetable inside target→
3. RRecast→
4. QDash→
5. AutocancelWeave→
6. WFinish

Tip Shadow Assassin R has increased cast and exit range, and Kayn is untargetable inside the target for up to 2.5 seconds. This is not blanket invulnerability—existing effects may remain—so use the window to avoid a key spell and refresh the passive cooldown. Recast early to exit in the chosen direction, chain W → Q → basic attack, and identify a wall for E afterward.

When Extended Darkin all-in against a bruiser or tank, sustaining through R

1. QEngage→
2. AutocancelWeave→
3. WKnock up→
4. RHeal

Tip In Darkin form, Q deals damage based on the target's maximum health and W knocks enemies up. After trading with Q-W, enter the target with R when healing is needed; emerging restores health based on the target's maximum health and buys time for the next Q and W while avoiding key abilities.

When Safe pre-transform poke in lane or jungle before disengaging

1. WPoke→
2. QChase→
3. EEscape

Tip W's 90% slow decays over 1.5 seconds, so Q in immediately and connect both of its damage instances. After the trade, enter nearby terrain with E for speed and its first-entry heal, but remember champion combat causes E to end early.

When Darkin surprise engage using Flash to land the knock-up

1. EApproach→
2. FlashFlash→
3. WKnock up→
4. QDamage→
5. AutocancelWeave→
6. RFinish

Tip W's knock-up requires Darkin form. Approach with E, Flash to close the gap and land an unexpected W, then Q → basic attack → R to finish.
