Given the greater health of enemies, and the higher ranks having even more same element resist compared to lower rank enemies, it is about time we have prism blades, to help s upport those with spells that are multi hit, such as damage over time spells and myth's double hits. Death ice myth and fire all have at least two spells that do damage over time or hit twice in a row. The method of filling up a deck with prism traps is just messy for these spells and schools. It would be a much more efficient to have prism blades, which will act like attack blades and work over the duration of the spells attack.
While the thought came to me that this would be a good thing, I think it would remove some the the deck building skills you develop for fighting your own school, and therefore make the game different.
Most of the time it isn't the MOBs you are worried about, it is the boss, so just toss the spell, boosting to overcome the resistances, then settle in on the bosses.
The problem does become much easier in CL once you start to crit, as the crit boost is usually much higher than what the MOBs reduce.
The problem with a Prism Blade is that blades get triggered first. The spell would be converted to the opposite school BEFORE it hit the school trap, thus leaving the trap alone. Also, if the Prism blade were triggered first, it would convert to the opposite school, preventing a school blade from also triggering.
I'd like cross-prisms. For example: Fire wizards get a prism that turns firedamage into ice damage. Wouldn't it be nice if you had also a prism that turns firedamage into stormdamage?

The same logic applies to traps and prisms. Depending on when the prism is placed along with the trap, the prism might not pick up your desired trap. Not much to really worry about if you can time your cast properly.
