How to play as Shaco
Use Two-Shiv Poison (E) to trigger Shroud of Darkness (W) before committing Jack In The Box (W) fear; otherwise Nocturne can block the key control spell.
Do not count on Hallucinate (R) to end an already attached Unspeakable Horror (E) tether; use Deceive (Q) early to leave its range or wait out the fear before re-engaging. (Unverified: no source confirms this note.)
Shroud of Darkness (W) blocks one Shaco spell, while Unspeakable Horror (E) can fear Shaco if he stays within tether range long enough.
How to play as Nocturne
Save Shroud of Darkness (W) for Shaco's box fear or Two-Shiv Poison (E), then keep Unspeakable Horror (E) tethered through the duel. (Unverified: no source confirms this note.)
