Editing Paragon Path (section)

===Resourceful Magician===
This path doubles down on your arcane fundamentals, requiring a bard to multiclass in any other arcane class. ''Greater Study'' acts as the improvement to any of your multiclass feats (Wizards now get all their cantrips, Sorcerers gain Resist 5 to one element whenever their bloodied and can use wands for their powers, Swordmages gain Swordbond and can use light and heavy blades as wands and vice versa,  Warlock gains Eldritch Blast as an at-will), ''Undaunted Action'' uses an AP to attack one extra target with a power that misses all other targets, and ''Diverse Study'' cuts your feat bloat by allowing you to swap out bard powers with multiclass powers whenever you get new powers. Twinned Spell is your saving throw, allowing you to use a missed attack once more. Spontaneous Action gives everyone a free move. Resourceful Trick is a versatile move, hitting one or two damage (with the power scaling being rather minor), variable typed damage, and a multitude of effects: sliding 2, pushing/pulling 4, dazing, or swapping places.

Considering that all the other arcane classes either use Cha or Int as main stats, you'd probably have a good shot with any of them as lead-ins, with cunning bards getting the most from wizards and swordmages.
