The plot needs 1.21 jigawatts (3.5)

Is there a source of electricity damage greater than an Elder Storm Elemental's Thunder and Lightning Ability (24d6 electricity damage)? It has to be a single burst of damage. Bonus points if it can be found from a monster instead of a spell or an optimized NPC, as my campaign setting is a "monsterverse".

[Eldest]

Yes. (http://www.d20srd.org/srd/monsters/dragonTrue.htm#blueDragon) Bonus points if you stack metabreath feats.

[TiaC]

Oceanus dragons can get to the same damage as the blue.

I assume epic magic is out?

[Fouredged Sword]

Yeah, a great wyrm silver dragon with maximize breath will do 192 damage, no roll, apply lingering and it deals an extra 96 the next round. The elemental deals 84 average, 144 max

Use Song of the Dead to turn any spell into a necromancy spell, and Reserves of Strength to remove the level cap from a spell. Cast a (Rod of) Maximized, Energy Substituted, Empowered, Song of the Dead, Reserves of Strength, Greater Fireburst for 50d10+1,000 electricity damage, average 1,275.

Doesn't Reserves of Strength only go up to +3, though?

What I linked only uses it for +1 caster level, but it still removes all level caps from whatever spell it's used on.

[Kazyan]

So it looks like big ol' dragons are a good choice. Anything else feasible?


I assume epic magic is out?

Indeed, but epic monsters are not.

Thought I'm a fan of your tricks, this is not plausible for my campaign setting. There are exactly 64 characters of level 17 or higher on the Material Plane, and they are generalist city-defenders. That's a lot of electricity damage, though.

ECL 12: Human Spellthief 1/ Warmage 1/ Wizard (Evoker) 3/ Ultimate Magus 7.
Two flaws, doesn't matter which ones. No class variants or alternate class features are required.
Master Spellthief, Theurgic Specialist, Reserves of Strength, Energy Substitution: Electricity, Empower Spell, Twin Spell, Metamagic School Focus: Evocation, Versatile Spellcaster, and Arcane Thesis: Greater Fireburst.
Ring of Arcane Might, Orange Prism Ioun Stone, Metamagic Rod of Maximize.

Spellcasting capability: Spellthief 1, Warmage 8, Wizard 7.
Caster Level: Master Spellthief (1+8+7)=16; Arcane Spell Power +3, Items +2, Total 21 for each of three classes.
Theurgic Specialist caster level for Greater Fireburst: 21+21+21 = 63, +2 for Arcane Thesis, +1 for Reserves of Strength = 66 Total

Greater Fireburst, cast via Warmage, spending two 4th level spell slots via Versatile Spellcaster:
Greater Fireburst: 5th level spell
Metamagic Rod of Maximize: +0 metamagic cost
Energy Substitution: Electric: +0 metamagic cost
Empower Spell: +2 metamagic cost
Twin Spell: +4 metamagic cost
Metamagic School Focus: -2 metamagic cost
Arcane Thesis: -4 metamagic cost
Total: 5th level spell slot (two 4th with Versatile Spellcaster)

Damage is 66d10+1320 + Int bonus electric, average 1683 + Int bonus.

Houseruled natural lightning. It does ∞d[DM] damage.

I prefer the lazy route.
