Final answer:
Omen's From the Shadows ability in VALORANT has around 1.5 seconds of channeling plus a 0.5 seconds vulnerability upon arrival, totaling approximately 2 seconds of cast time.
Step-by-step explanation:
The Total Cast Time for Omens' From the Shadows (X) ability in the game VALORANT consists of a brief channel period before teleporting and a brief delay upon arrival at the teleport location. The initial cast is nearly instantaneous, but there is a channeling time reported to be around 1.5 seconds. Upon arrival, Omen is also vulnerable for a short duration - usually around 0.5 seconds - before being able to move or use weapons. It is essential for players to seek cover or ensure it is safe before using this ability, as Omen can be killed during the teleportation's brief vulnerable phase.
