Note that the Dragonlance War Mage has been greatly nerfed. It was the most powerful arcane PrC around. Now it is only very, very powerful.
5 levels to get:
+3 untyped bonus damage per die of damage (!!!)
Cha bonus to defelection AC for 3 allies
2 Metamagic feats of choice
It was simply insane.
Go for Dalamar's Lighning Lance. An empowered version of this spell will do:
13d6+39 (untyped, no save) and 45d6+135 (electricity, Fort. for half)
Even if the target makes all the saves, it is still in for some 200 points of damage - from a 6th level spell slot! It is one of the most blatantly overpowered combos available, without any questionable metamagic feats/rules/lenient DMs.
Hint: You should boost your Con for the erratum version!
