Metamagic rod, ectoplasmic works on what kinds of spells?


Rules Questions


The rod just states that the rod works like the feat.
The feat just states that the modified spell has full effect on incorporeal and ethereal creatures.

I'm pretty sure it will work with flame blade to make the flame blade work vs those creatures.

But what about magic fang / magic weapon? Does it only enable me to cast magic fang on an incorporeal creature or does let the enchanted creature hurt ghosts?

What about summon monster or summon swarm?


I just picked up this rod during Carrion Crown. I'm interested to see what ideas people might suggest. On the surface it seems generally situational.

Incorporeal creatures take half damage (50%) from magic weapons, spells, spell-like effects, and supernatural effects.

Corporeal spells and effects that do not cause damage only have a 50% chance of affecting an incorporeal creature.

An ectoplasmic spell has full effect against incorporeal or ethereal creatures.

If you cast magic fang on an incorporeal creature, normally you have a 50% chance for it to have no effect. If you cast ectoplasmic magic fang, it has full effect.

Summoned monsters would not be any different than normal. It's not the spell that's attacking the ghost, it's the celestial wolf or whatever.


What about a ectoplasmic barkskin?
Will it protect against incorporeals?


It will only work on spells that target that directly affect the creature, as the feat reads:
"Benefit: An ectoplasmic spell has full effect against incorporeal or ethereal creatures."

The magic weapon spell affects the weapon and not the target. The magic fang spell does the same thing. Simply having a magic weapon does not negate the incorporeal or ethereal conditions.

The Flame Blade is a little trickier as it is an energy attack that is treated like a touch attack. It is not really your hand attacking the target. I would rule that it would allow the spell to be used against incorporeal without the 1/2 damage (providing you hit) and against ethereal as if non-ethereal. Usually it takes a force spell to affect ethereal targets.

I would say no to the SM and SS as it is not the spell that attacks, but the creatures. The thought of an ectoplasmic swarm is cool however.......

Ectoplasmic barkskin will affect an incorporeal creature 100% of the time, giving it the +X bonus to natural armor. It will NOT have any different affect if you cast it on yourself (in other words, casting an ectoplasmic barkskin on a corporeal creature will have the exact same effect as a normal version of the spell.)

"An incorporeal creature’s attacks pass through (ignore) natural armor, armor, and shields, although deflection bonuses and force effects (such as mage armor) work normally against it."

This means that even if you were to cast an Ectoplasmic version of barkskin on yourself, you're still getting a bonus to natural armor, which incorporeal creatures can ignore.
