KI, you really need to upgrade the Lightning Strike charm. I don't mean make it go from +10% accuracy to +15% accuracy or +20% accuracy, but make it so it ONLY works for damage spells. I can't tell you how many times I've accidently used up the charm while putting up a blade or trap. Just saying, I think it should be changed.
Give it time, eventually, you will get to where you never even have to use this spell ever again.
Just be patient. Always remember, blade first, then put your accuracy spell on. No reason to change it, just keep in mind, it boosts accuracy on all storm spells.
