A spell which can work like 'Rapid Fire' in its duration and cool-down which allows a spell prepared under its effects to raise the duration of the spellup on other parties (if necessary) and if casting a hostile spell then the effects would be like a multiplied or concentrated exaggeration of the spell successful to harm a foe.

For example:

A 409 E-blast would focus more mana and power into the target but at a much higher mana cost, perhaps at a multiplier on a factor based on the predetermined level of power of the spell. So five E-blasts at once concentrate into the TARGET and if successful deliver a much more powerful blow.

A 414 on a player would be a maximum 4 hour cast at a higher mana consumption rate. If the casting wizard has the ranks and level to get a full four hours+ from a single cast, then the mana cost can be reduced on an inverse scale.

A bonus to Enchanting success odds!

For the minute, a chance of the field deflecting any incoming attacks,especially magical (perhaps making flares upon contact).

It would be really great if doing this to 902 or E-Blade could make the weapon characteristics much more advanced.

Maybe an option in the VERB used to deliver it, so like of it's actually INVOKED rather than cast or incanted or whatever else that it can be an energy ball spell which works as a Maneuver based attack sort of like bowling.
