When have we ever learned any lessons before? When have we ever learned that particular lesson even?

A few thoughts: do we have enough in our stash of lab supplies for me to make something using this scale we picked up that would give me an enhanced arcane connection to the dragon, either as in scrying or allowing touch spells at range, possible discounts for single use or keyed to particular spell. Failing that, is there enough for me to make a grenade of touch of idiocy?
