Keep in mind it's Dalamar's Lightning Lance, which is found in the Dragonlance Campaign Setting book. That one's still technically 1st party, while all the other Dragonlance books are 2nd party.
That's a different spell. Nytemare is talking about Thunderlance (Sorc/Wiz 4), from Spell Compendium pg 220. Also note that it has a fixed range (0 ft), so it's persistable with metamagic reducers.
Attacks vs normal (not touch) AC for 3d6 damage, is two-handable for 2:1 PA returns, strikes as a force effect (no energy resistance or DR), and gives you a 20' reach. Oh, and has a chance of dispelling certain magical protections.
I'm also a fan of Ice Axe, from Spell Compendium pg 118. Cleric 3, persistable, strikes vs touch AC, 2 handable, 2d12 + 1/2 CL damage.
