Stormborn Ride The Lightning

[Coridan]

So a question on how this works. First, the two relevant parts of rules

Thunderbolt:

Thunderbolt (Sp): At 9th level, you can command a stroke of lightning to strike from above in a 5-foot-radius cylinder 60 feet high. The thunderbolt inflicts 1d6 points of damage per sorcerer level; half of this damage is electricity and half is sonic. A Reflex save (DC 10 + 1/2 your sorcerer level + your Charisma modifier) halves this damage. Creatures failing their saves are deafened for 1 round. At 9th level, you can use this ability once per day, at 17th twice per day, and at 20th three times per day. This power has a range of 120 feet.

and

Ride the Lightning:

Ride the Lightning (Sp): At 15th level, as a full-round action you can become a living lightning bolt and move in a straight line up to 10 times your speed. You do not provoke attacks of opportunity while moving in this way. Creatures or objects in your path are affected as by your thunderbolt power. Creatures do not block your movement but solid barriers do unless they are reduced to 0 hit points. You can use this power once per day for a number of rounds equal to your sorcerer level.

So with Ride the Lightning as a full round action I can become a living lightning bolt, travel we'll say 300 feet and zap everyone in the way for 15d6 electric, and keep doing it for 15 rounds straight?

That's the gist! But it's worth noting that, line spells, while cool, rarely work more than once per combat. This one may almost be more useful as a transport trick than an attack spell.

I never thought about it before, but you could fry an army with that.

Assuming a base 30' speed with no modifiers (not sure they apply) that is at least 600' feet a round you move.

That is a lot of peasants or orcs you could kill each round.

Being an uberpowered version of Spring Attack that can deal (minimum) 15d6 for 15 rounds (225d6, an average of 787 damage) with little or no risk of being countered/damaged/stopped, and even less chance of having your target(s) flee, hardly you can say it's not good for attacking. You could storm a castle alone in 90 seconds.

Actually, for a base speed of 30 feet, that is a maximum of 300 feet.

"Up to 10 times your speed", doesn't matter if you make double movement, run or whatever. Besides, you couldn't do that, since this kind of movement is itself a full-round action.
