Lightning based blaster build?

[Psyren]

Scribe Wizard's perks beside the damage type permutation make the Scribe Wizard a better Lighnting Blaster than Draconic Sorcerer?

Surprising claim.

While the damage type manipulation is indeed the biggest advantage of a Scribes Wizard for a lightning build, the other points Ludic raised do matter too. Many blasting spells, and most lightning spells in particular, rely on precise positioning to be most effective - Lightning Bolt is a line, Dragon's Breath is a cone, Shocking Grasp is touch, Chain Lightning rewards you for picking the primary target with the most visible secondary targets in proximity, Witch Bolt needs you to remain within walking distance of the enemy etc. Scribes letting you pick targets from and originate your attack spells from a point you yourself are not standing in is a concrete benefit this subclass brings to lightning build.

Which is not to say these are the spells you'll be using most of the time anyway, as thanks to Scribes your lightning build has far higher-damage spells to bring to the table - things like Heat Metal, Spike Growth, Fireball and Wall of Fire all allowed to be Awakened into being lightning spells is of course the primary benefit. But if you are forced to use actual printed lightning spells, you can use them more effectively than most wizards, even including Evokers in many cases.
