Spell Effect delay

Is there different times for a spells to take effect? Earlier tonight I was knocked of a very long fall by a moving trap I immediately cast levitate, but I still splatted on the floor even with the effect icon up, The next time it happened I used slow fall on the way down and it worked as it should allowing me to survive the fall. Does anyone know what the cast delay is for levitate to take effect? I usually just use it for platform transition so not casting it while falling which didn't seem to work.

That's strange. I remember jumping in a well and levitating midway without a problem. IIRC, it was instantaneous.

Why did I cast levitate after jumping in a well? Because while I was falling, I was still deciding whether to cast levitate or slow falling
