If it is a standard action to place Evil Eye and a move action to Cackle in order to extend the duration of Evil Eye by one round could you:
Use Evil Eye and the Cackle immediately after to cause the Evil Eye to have a minimum duration of 2 rounds?
The idea being that you could use Evil Eye to lower a foe's saves, If the foe passes they would return to normal before your next turn BUT if you Cackle and extend the duration you could Evil Eye on your next turn and since they have the penalty to saves you have a better chance of getting the GOOD duration?
I feel like RAW this is a viable strategy.
