By rights the Venom Staff can be used twice per second at the absolute maximum (the lowest that the use time can get is 27, there are 60 frames rendered per second in an optimal setup) bringing the mana cost to 50/sec. It's still lower overall than the Last Prism which is a whole 44% more mana-hungry.

The Last Prism has lower mana cost if you simply use it and immediately stop using it, however that is not its intended use. If both are used in the manner that they are intended, the Last Prism is more mana-expensive.
